A retailer in New York is comparing two natural diamonds for the same engagement-ring client.

Both are one carat.

Both are G colour.

Both are certified.

Both look clean to the naked eye.

Yet one is priced noticeably higher.

The difference is Clarity.

One diamond is VVS2. The other is VS2.

To the customer, the distinction is not immediately visible. Under ordinary viewing conditions, both appear clean. The retailer therefore faces one of the most important questions in diamond selling:

If the customer cannot see the difference, when is it worth paying for the higher Clarity grade?

That is where Clarity becomes more than a laboratory specification.

For professional buyers, Clarity affects:

pricing,

inventory positioning,

customer perception,

and value.

But the most profitable Clarity strategy is not simply:

buy the highest grade possible.

It is understanding what the grade actually means, what type of inclusion created it, where that inclusion sits, whether it is visible face-up and whether moving to a higher grade produces a meaningful visual benefit.

For Dalila Diamonds, this creates a useful B2B sourcing role. A retailer requesting a natural diamond should not only be able to specify:

VS2

or

SI1.

They should be able to ask for:

an eye-clean VS2 with no distracting central dark inclusion

or:

an SI1 where the grade-setting inclusion is discreet and does not compromise transparency or durability.

That is the difference between buying a label and selecting an actual diamond.

Quick Answer: What Are Diamond Clarity Grades?

Diamond Clarity grades describe the presence, size, number, position, nature and visibility of internal characteristics called inclusions and external characteristics called blemishes.

The commonly used GIA Clarity scale runs from:

Flawless (FL)

through

Internally Flawless (IF)

VVS1 and VVS2

VS1 and VS2

SI1 and SI2

to

Included categories I1, I2 and I3.

Higher grades indicate fewer or less significant clarity characteristics under standard grading conditions.

But for retailers, the most important practical question is often:

Is the diamond visually clean enough for the customer?

That is why VS2 and carefully selected SI1 diamonds can sometimes offer stronger value than much higher Clarity grades.

What Does Diamond Clarity Actually Measure?

Natural diamonds form under extreme conditions inside the Earth.

During that growth process, they can develop internal characteristics.

These are called:

inclusions.

Characteristics occurring on the surface are generally called:

blemishes.

Clarity grading evaluates how significant those features are.

The grade does not simply count inclusions.

A single inclusion can be more important than several smaller ones depending on:

its size,

its location,

its type,

its relief,

and how easy it is to see.

That is why two diamonds with the same Clarity grade may look different.

This distinction matters because customers often use the word:

imperfection

for everything.

Professional retailers should be more precise.

The Full Diamond Clarity Scale

The Clarity scale can be understood as a progression from extremely rare stones with no visible clarity characteristics under standard magnification to diamonds whose inclusions are more obvious.

GradeFull NameGeneral InterpretationFLFlawlessNo inclusions or blemishes visible under standard grading conditionsIFInternally FlawlessNo inclusions visible; only minor surface blemishes may be presentVVS1Very Very Slightly Included 1Minute inclusions, extremely difficult to detectVVS2Very Very Slightly Included 2Minute inclusions, still very difficult to detectVS1Very Slightly Included 1Minor inclusions, difficult to somewhat easier to detect under magnificationVS2Very Slightly Included 2Minor inclusions visible under magnificationSI1Slightly Included 1Noticeable inclusions under magnification; may still be eye-cleanSI2Slightly Included 2More obvious inclusions; eye-clean examples are less commonI1Included 1Inclusions may be visible without magnificationI2Included 2Inclusions generally more obviousI3Included 3Significant inclusions may affect appearance or durability

The Clarity scale is technical.

Retail buying is commercial.

Those two viewpoints need to work together.

Flawless Diamonds: Technically Exceptional, Commercially Specific

Flawless diamonds occupy the top of the Clarity scale.

They are rare.

They are also expensive.

For collectors, very high-net-worth clients or buyers specifically seeking exceptional laboratory specifications, FL can carry prestige.

But for the majority of engagement-ring customers, paying the premium for Flawless does not necessarily create a visible benefit compared with:

VVS,

VS,

or even a carefully selected SI stone.

The retailer therefore needs to identify whether the client is buying:

technical rarity

or

visible beauty.

Those are not always the same goal.

FL vs IF

Flawless and Internally Flawless diamonds are extremely close in market positioning.

The distinction is mainly that an IF diamond may have minor surface blemishes while lacking internal inclusions visible under standard grading conditions.

For most retail customers, the visual difference between:

FL

and

IF

will not be perceptible without magnification.

Therefore this category usually sells on:

rarity,

prestige,

and technical specification.

VVS Clarity: Premium Without Flawless Pricing

VVS1 and VVS2 diamonds contain minute clarity characteristics that are extremely difficult to see under magnification.

For premium natural-diamond buyers, VVS offers:

very high Clarity,

strong grading appeal,

and a meaningful luxury positioning

without necessarily reaching the price of FL or IF.

But again, a customer viewing the diamond normally may see no practical difference between:

VVS2

and

VS1.

That is why retailers should be careful about framing VVS as:

“more beautiful.”

It is:

a higher Clarity grade.

That is different.

For customers who want:

very high specifications

but do not require:

Flawless,

VVS2 can often provide a strong compromise.

VS Clarity: The Commercial Sweet Spot

For many retailers, VS1 and VS2 represent one of the strongest commercial Clarity ranges.

Why?

Because the inclusions are usually:

minor,

difficult to see without magnification,

and often irrelevant to normal face-up viewing.

At the same time, pricing can be meaningfully lower than VVS.

That creates the exact balance many engagement-ring customers want:

high apparent quality

without paying for microscopic rarity they cannot see.

VS1 vs VS2

VS1

Usually offers a very high probability of appearing clean under ordinary viewing.

VS2

Often offers similar visual cleanliness but at a more efficient price.

For a retailer building core inventory, VS2 can be especially useful.

But only if the actual inclusion is acceptable.

Why VS2 Is Not Automatically Eye-Clean

This is important.

Retailers sometimes say:

“VS2 is always eye-clean.”

That is too broad.

Most VS2 natural diamonds may look clean to many customers under normal conditions, but visibility depends on:

stone size,

shape,

inclusion type,

inclusion position,

and viewing distance.

A 0.70 ct Round Brilliant VS2 may be extremely easy to sell as eye-clean.

A 4 ct Emerald Cut VS2 with a dark central inclusion may require more careful evaluation.

The grade alone does not decide.

SI1: Where Professional Buying Can Create Strong Value

SI1 is one of the most interesting Clarity categories for experienced buyers.

Some SI1 diamonds contain inclusions that are:

visible under magnification

but

very difficult to see face-up without it.

Others are visibly included.

That variation creates both:

risk

and

opportunity.

A retailer who simply filters:

SI1 = bad

may miss excellent value.

A retailer who buys every SI1 without inspection may create inventory problems.

Professional sourcing sits between those extremes.

Example: Three SI1 Diamonds

Diamond A

1.00 ct Round

small feather near edge.

Appears clean face-up.

Diamond B

1.00 ct Round

dark crystal under centre.

Visible without magnification.

Diamond C

1.00 ct Round

cloud-related characteristics creating slightly reduced transparency.

All three may share the same broad SI1 label.

Their retail appeal is completely different.

SI1 vs VS2

This is one of the most commercially important Clarity comparisons.

FactorVS2SI1Technical gradeHigherLowerEye-clean probabilityHigherMore variablePriceHigherOften lowerInspection needModerateHighValue opportunityStrongPotentially excellentBest forCore inventoryCarefully selected value inventory

If an SI1 is:

eye-clean,

transparent,

durable,

and well cut,

it can sometimes produce an exceptional retail proposition.

SI2: Much More Selective

SI2 requires substantially more caution.

Some SI2 stones may still be suitable for certain:

small diamonds,

multi-stone jewellery,

or price-sensitive applications.

But for centre stones, especially larger ones, inclusions are more likely to be visible.

This does not make SI2 universally unsuitable.

It means:

visual inspection becomes essential.

Included Diamonds: I1, I2 and I3

Included diamonds contain clarity characteristics that are more obvious.

Depending on severity, they may affect:

appearance,

transparency,

or durability.

These grades can still have commercial uses.

Examples include:

lower-priced jewellery,

certain melee applications,

or clients prioritising size over microscopic cleanliness.

But retailers should be particularly careful with:

durability-related inclusions.

A visibly included diamond is not simply:

a cheaper version of a clean one.

The actual inclusion structure matters.

What Does “Eye-Clean” Mean?

Eye-clean is one of the most useful retail concepts in diamond buying.

But it is not a formal Clarity grade.

A retailer should therefore define it consistently.

For example:

No inclusion readily visible face-up to a person with normal vision at approximately 20–30 cm under normal viewing conditions.

Another business might use a different internal standard.

What matters is consistency.

Eye-Clean Is Not Universal

A diamond might be eye-clean:

face-up

but not:

from the side.

It may be eye-clean:

at 30 cm

but not:

at 10 cm.

A retailer should therefore avoid saying:

“completely flawless to the naked eye.”

unless that claim has actually been evaluated according to a clear standard.

Why Eye-Clean Matters More Than Microscopic Perfection for Many Buyers

Most customers do not wear their engagement rings with:

10× magnification.

They experience the diamond:

across a dinner table,

in daylight,

in office lighting,

in photographs,

and on the hand.

That makes visible cleanliness commercially important.

A perfectly eye-clean VS2 may produce the same normal-viewing experience as a VVS1 while allowing the customer to allocate budget toward:

Carat,

Cut,

Colour,

or setting.

That is where Clarity strategy becomes valuable.

Clarity and Price

Clarity can influence diamond pricing significantly.

As the grade improves, the supply of qualifying natural diamonds becomes smaller.

But the visual improvement does not always rise at the same rate as price.

The difference between:

SI1 and VS1

may be clearly visible in one pair of stones.

In another comparison, it may be extremely subtle without magnification.

The same is true between:

VS1 and VVS1.

This is why professional buying should focus on:

visual consequence per unit of price.

Example Clarity Price Logic

Consider three hypothetical one-carat Round Brilliants.

OptionClarityFace-Up AppearancePricing PositionAVVS2Eye-cleanPremiumBVS2Eye-cleanBalancedCSI1Eye-cleanValue

If all three look equally clean to the customer, the buying decision shifts toward:

rarity,

certificate preference,

and budget.

There is no universal reason every customer should choose A.

Clarity Is Not a Profit Margin Trick

The original draft framed lower Clarity partly as a way to maximise retailer margin.

That needs refinement.

Retailers should not recommend a lower grade merely because it creates more margin.

The correct goal is:

find the Clarity level that gives the customer the best balance of visible quality, technical specification and price.

Profitability comes from:

good sourcing,

transparent positioning,

and efficient inventory.

Not from hiding grade differences.

Types of Diamond Inclusions

Common clarity characteristics include:

crystals,

feathers,

clouds,

needles,

pinpoints,

and cavities.

Their commercial importance varies substantially.

Crystal

A crystal is a mineral inclusion trapped inside the diamond.

It may appear:

colourless,

dark,

or coloured.

A tiny pale crystal near the edge may be nearly irrelevant visually.

A black crystal under the table may be much more obvious.

Feather

A feather is an internal break or fracture-like clarity characteristic.

Many feathers are small and harmless.

Larger feathers near:

the girdle

or

surface

deserve additional durability consideration.

A retailer should not automatically reject every diamond containing a feather.

The size and location matter.

Cloud

A cloud is a group of tiny pinpoints.

Small clouds may have little visual effect.

More extensive clouds can sometimes influence transparency.

This is why comments such as:

“clarity grade based on clouds that are not shown”

deserve careful review when evaluating the actual stone.

Pinpoint

A pinpoint is a very small inclusion.

Single pinpoints often have minimal practical impact.

Groups of pinpoints may form a cloud.

Needle

A needle is a thin elongated inclusion.

Like most clarity characteristics, its significance depends on:

size,

location,

and visibility.

Inclusion Type Comparison

InclusionMain Retail ConcernCrystalVisibilityFeatherVisibility + possible durabilityCloudPotential transparency impactPinpointUsually minor unless numerousNeedleVisibilityCavitySurface/durability considerationNaturalOften near girdle; review placement

The grade alone does not tell the retailer which of these characteristics created it.

Inclusion Location Matters

Imagine two VS2 diamonds.

Diamond A

Small inclusion hidden near the girdle.

Diamond B

Dark inclusion directly beneath the table.

Both have the same grade.

Diamond A may be much easier to sell.

This is why inclusion position is one of the most important factors beyond the Clarity label.

Can a Prong Hide an Inclusion?

Sometimes.

An edge inclusion may become less visible after setting.

But retailers should be careful not to use prongs to:

conceal a durability problem.

A jeweller should review whether the inclusion is appropriate for that setting before deliberately positioning metal over it.

Clarity Plot: Read It, but Do Not Stop There

Many grading reports include a clarity plot showing the approximate type and location of clarity characteristics.

This can help the retailer understand:

where the inclusions are

and

what kind they are.

But a plot is not a photographic representation.

The apparent size of a plotted symbol does not always equal:

how obvious the characteristic will look in the actual stone.

Use the plot as:

a map.

Then inspect the diamond.

Comments Section

The comments area of a grading report can contain important information.

Examples might include:

additional clouds not shown,

surface graining,

internal graining,

or laser inscriptions.

Retailers should review comments rather than looking only at:

Carat,

Colour,

Clarity,

and Cut.

Clarity and Diamond Shape

Different shapes reveal inclusions differently.

A Round Brilliant uses many facets and significant scintillation, which can make some inclusions less obvious.

An Emerald Cut has large open step facets.

That makes internal characteristics easier to see.

Therefore:

VS2 in Round

and

VS2 in Emerald

do not always create the same face-up experience.

Clarity by Shape

ShapeClarity SensitivityRound BrilliantMore forgivingOvalRelatively forgiving, but central inclusions matterPearSimilar to OvalMarquiseSimilar to other brilliant fancy shapesCushionDepends heavily on facet styleRadiantCan hide inclusions wellEmeraldHigh visibilityAsscherHigh visibilityHeartShape and central area need inspection

This is why one Clarity strategy should not be applied to every shape.

Round Brilliant Clarity Strategy

For many Round engagement-ring clients:

VS2

or

selected SI1

can provide excellent visual value.

Premium buyers may choose:

VS1,

VVS2,

or higher.

The correct choice depends on:

budget

and

whether the specification itself has emotional importance.

Oval Clarity Strategy

Ovals can sometimes disguise inclusions through their brilliant-style faceting.

However, the buyer should examine:

the centre,

bow-tie area,

and inclusion placement.

A central dark inclusion can combine poorly with a strong bow-tie.

Emerald Cut Clarity Strategy

Emerald Cuts require more scrutiny.

Their broad step facets provide a clearer view into the stone.

That can make inclusions easier to identify.

Retailers often prioritise:

VS1,

VS2,

or higher

for significant Emerald Cuts, depending on the actual stone.

But even then:

a beautiful eye-clean VS2 may be preferable to paying for unnecessary VVS Clarity.

Asscher Clarity Strategy

Asscher Cuts behave similarly to Emerald Cuts in that their open step pattern can expose inclusions.

A clean centre becomes particularly valuable.

For larger Asscher diamonds, high-quality video or physical inspection is strongly recommended.

Clarity and Carat Weight

As Carat increases, inclusions can become easier to see simply because the diamond itself is larger.

For example:

a tiny crystal may be nearly invisible in a 0.50 ct stone.

At 3 ct, similar clarity characteristics can be easier to locate.

Therefore Clarity strategy should become more selective as size increases.

Practical Clarity by Carat

CaratCommon Retail ApproachUnder 1 ctVS2 / selected SI1 can work well1–2 ctVS2 remains strong; inspect SI12–3 ctInclusion location increasingly important3 ct+Strong visual review essential

These are sourcing tendencies, not hard rules.

Clarity and Cut

A common claim is:

“Better Cut hides inclusions.”

That needs nuance.

Strong Cut can create more:

brightness,

scintillation,

and visual activity,

which may make some inclusions less noticeable under normal viewing.

But Cut does not remove an inclusion.

A dark crystal beneath the table can remain visible even in an Excellent Cut diamond.

Therefore:

Cut and Clarity interact visually,

but one does not replace the other.

Clarity and Colour

Clarity and Colour are separate grading characteristics.

A higher Clarity grade does not make a diamond:

whiter.

A higher Colour grade does not make a diamond:

cleaner.

Retailers should avoid combining them into one vague concept of:

“quality.”

Instead, explain the trade-offs separately.

VS2 vs VVS2: What Should the Customer Buy?

If both stones appear identical without magnification, the decision becomes:

does the customer value the premium Clarity specification?

Some do.

They may want:

VVS

because the report itself matters.

Others prefer to put that money toward:

larger Carat,

higher Colour,

or a more elaborate setting.

Neither is wrong.

The retailer's role is to clarify the trade-off.

VS1 vs VS2

For many customers, these can be especially difficult to distinguish visually.

VS1 provides:

a higher technical Clarity grade.

VS2 often provides:

excellent visible cleanliness at lower cost.

This makes VS2 one of the most important categories for commercial engagement-ring stock.

VVS vs SI: Is the Premium Worth It?

Sometimes.

But not always.

A VVS2 may be the right choice for:

a collector,

a private client demanding high specs,

or a premium brand positioning.

A clean SI1 may be stronger for:

a value-focused customer

who prioritises:

Carat and appearance.

This is why selling only one Clarity band limits a retailer's ability to serve different client priorities.

A Better Clarity Inventory Strategy

Instead of stocking:

only VVS

or

only SI,

build clear tiers.

Premium

VVS2–VS1.

Core

VS1–VS2.

Value

Selected eye-clean SI1.

This gives customers meaningful choices.

Example Retail Clarity Ladder

TierExamplePremiumG VVS2BalancedG VS2ValueG SI1, eye-cleanSize-priorityH SI1 with strong Cut

Now the retailer can explain why each diamond exists in the assortment.

Clarity Strategy for High-End Retailers

A luxury brand may decide that:

VS1

is the lowest core Clarity it wants to present.

That can be valid if the brand's positioning requires it.

But it should be a deliberate merchandising choice.

Not a claim that:

anything below VS1 is poor quality.

A carefully selected VS2 or SI1 can still be beautiful.

Clarity Strategy for Value-Led Retailers

A value-focused store may work more heavily with:

VS2

and

SI1.

The key is quality control.

A lower Clarity strategy only works if:

the retailer rejects weak stones.

Otherwise:

the category becomes associated with visible inclusions instead of value.

Clarity Strategy for Bespoke Retailers

Bespoke jewellers have more flexibility.

Rather than carrying deep inventory, they can source according to:

client budget,

Carat,

shape,

and Clarity tolerance.

For one customer:

VVS2.

For another:

eye-clean SI1.

The appropriate answer can change with every commission.

Clarity in Matched Pairs

For earrings, both diamonds should not necessarily have identical microscopic inclusion patterns.

They should match visually.

Example:

Diamond A:

0.50 G VS2.

Diamond B:

0.51 G VS1.

If they:

match in diameter,

Colour,

Cut,

and face-up appearance,

they may make a stronger pair than two VS2 stones with poor dimensional matching.

Clarity in Tennis Bracelets

Individual stones in a tennis bracelet are much smaller.

Customers do not evaluate each diamond under magnification.

The priorities shift toward:

matching,

sparkle,

overall Colour consistency,

and clean visual appearance across the line.

Extremely high Clarity grades may not provide meaningful retail benefit in many tennis-bracelet applications.

Clarity in Halo and Pavé Jewellery

The same applies to small accent diamonds.

A halo may use:

small calibrated stones.

The visual effect depends on:

uniformity,

Cut,

and matching.

High microscopic Clarity may matter less than:

overall consistency.

Does Clarity Affect Sparkle?

Clarity itself does not create sparkle.

Cut is the primary driver of:

brightness,

fire,

and scintillation.

However, severe inclusions or reduced transparency can interfere with visual performance.

Therefore a heavily included diamond can look less lively.

But moving from:

VS2

to

VVS1

does not automatically make a well-cut diamond sparkle more.

Does Clarity Affect Durability?

Sometimes.

Most ordinary inclusions do not create a durability concern.

But certain larger features—especially fractures reaching vulnerable areas—deserve professional evaluation.

Retailers should not alarm customers by saying:

“feathers mean diamonds can break.”

Most feathers do not create that outcome.

The actual inclusion needs context.

Does Clarity Affect Resale Value?

Clarity can influence resale desirability and pricing.

But resale value depends on much more than:

Clarity alone.

It also depends on:

Carat,

Colour,

Cut,

shape,

certification,

market conditions,

and current buyer demand.

Retailers should avoid promising that a VVS diamond:

will hold value better

without context.

Higher Clarity Is Not Automatically a Better Investment

A 1 ct D VVS1 may be technically rarer than:

a 1 ct G VS2.

But the better resale outcome depends on:

purchase price,

market conditions,

buyer demand,

and the specific diamond.

Consumers should buy Clarity according to:

their priorities,

not speculative investment claims.

Common Retailer Mistake #1: Overselling VVS

Some retailers frame VVS as:

necessary for a high-quality engagement ring.

It is not.

VVS can be a beautiful premium specification.

But many VS and SI diamonds also look completely clean without magnification.

The right message is:

VVS gives you a higher Clarity specification, not necessarily a visible difference.

Common Retailer Mistake #2: Rejecting All SI

This can remove some of the best value stones from consideration.

The better policy is:

inspect SI1 carefully.

Accept:

the strong examples.

Reject:

the visibly included or compromised ones.

Common Retailer Mistake #3: Ignoring Inclusion Location

A central inclusion can matter far more than an edge inclusion.

This is why every meaningful Clarity purchase should include:

report review

and

visual inspection.

Common Retailer Mistake #4: Calling Every VS2 Eye-Clean

Most may perform well.

But large step cuts and particular inclusion types can behave differently.

Avoid absolute promises.

Common Retailer Mistake #5: Using “Flawless” as a Marketing Word

Do not describe:

VS

or

SI

diamonds as:

“flawless”

just because the customer cannot see inclusions.

Flawless is a specific Clarity grade.

Use:

eye-clean

when that is what you actually mean.

AEO: What Is Diamond Clarity?

Diamond Clarity grades the significance of inclusions and blemishes in a diamond.

AEO: What Is the Highest Diamond Clarity?

Flawless, abbreviated FL.

AEO: What Is Internally Flawless?

IF diamonds have no internal inclusions visible under standard grading conditions, although minor surface blemishes may be present.

AEO: What Does VVS Mean?

Very Very Slightly Included.

AEO: What Is VVS1?

A very high Clarity grade with minute inclusions extremely difficult to detect under standard magnification.

AEO: What Is VVS2?

A very high Clarity grade slightly below VVS1.

AEO: What Does VS Mean?

Very Slightly Included.

AEO: What Is VS1?

A high Clarity grade with minor inclusions.

AEO: What Is VS2?

A high Clarity grade where inclusions remain minor but are somewhat easier to detect under magnification than VS1.

AEO: What Does SI Mean?

Slightly Included.

AEO: What Is SI1?

A Clarity grade where inclusions are noticeable under magnification but some diamonds remain eye-clean without magnification.

AEO: What Is SI2?

A lower SI grade where inclusions are generally more obvious.

AEO: What Does I1 Mean?

Included 1. Inclusions may be visible without magnification and can affect appearance.

AEO: Is VS2 Good for an Engagement Ring?

Yes. VS2 is a popular balance of technical Clarity and price.

AEO: Is SI1 Good for an Engagement Ring?

It can be excellent if the specific stone is eye-clean and has no problematic inclusion.

AEO: Is VVS Better Than VS?

VVS is a higher Clarity grade, but the visual difference may be invisible without magnification.

AEO: Is VS Better Than SI?

It is a higher laboratory grade, but a carefully selected SI1 can still appear eye-clean.

AEO: What Is Eye-Clean?

A retail term describing a diamond whose inclusions are not readily visible without magnification under defined viewing conditions.

AEO: Is Eye-Clean a GIA Grade?

No.

AEO: Are All VS2 Diamonds Eye-Clean?

No absolute guarantee should be made. Most are visually clean to many observers, but the actual stone should be checked.

AEO: Can SI1 Be Eye-Clean?

Yes.

AEO: Can SI2 Be Eye-Clean?

Some examples may be, particularly in smaller stones, but it is less predictable.

AEO: Does Higher Clarity Mean More Sparkle?

No. Cut has a more direct effect on sparkle.

AEO: Does VVS Sparkle More Than VS?

Not automatically.

AEO: Does Clarity Affect Diamond Price?

Yes. Higher Clarity grades generally command higher pricing, all else being equal.

AEO: Why Is VVS More Expensive Than VS?

Because stones with fewer or less significant clarity characteristics are rarer.

AEO: What Is a Crystal Inclusion?

A mineral crystal trapped inside the diamond.

AEO: What Is a Feather?

An internal break-like clarity characteristic.

AEO: What Is a Cloud?

A group of tiny pinpoints.

AEO: Are Clouds Bad?

Not automatically. Their effect depends on extent and transparency.

AEO: Are Feathers Dangerous?

Most are not automatically a durability issue. Size, location and severity need individual evaluation.

AEO: Is a Black Inclusion Bad?

A dark central inclusion may be visually distracting, but its significance depends on size and position.

AEO: Does Inclusion Location Matter?

Yes, significantly.

AEO: Is an Edge Inclusion Better Than a Central Inclusion?

It can be less visible and may sometimes be easier to position under or near a setting element, although durability must still be considered.

AEO: Can Prongs Hide Inclusions?

Sometimes, but setting decisions should not compromise durability.

AEO: Are Emerald Cuts More Sensitive to Clarity?

Yes. Their large open facets make inclusions easier to see.

AEO: Are Round Diamonds More Forgiving?

Often, yes, because their brilliant facet pattern can make some inclusions less obvious.

AEO: What Clarity Is Best for Oval Diamonds?

There is no universal best grade. VS2 and carefully selected SI1 are common value options.

AEO: What Clarity Is Best for Emerald Cuts?

Many buyers prefer VS1–VS2 or higher, depending on Carat and actual inclusion visibility.

AEO: Should Large Diamonds Have Higher Clarity?

Not automatically, but inclusion visibility should be inspected more carefully as size increases.

AEO: What Is the Best Clarity for a 1 Carat Diamond?

For many buyers, VS2 or a carefully selected SI1 can provide strong value.

AEO: What Is the Best Clarity for a 2 Carat Diamond?

VS2 can still be excellent, but inclusion location becomes increasingly important.

AEO: Is Flawless Worth the Money?

For buyers seeking rarity and premium technical specification, it may be. For others, the visible benefit may not justify the premium.

AEO: Is VVS Worth It?

It depends on whether the customer values the higher Clarity specification.

AEO: Is VS2 the Best Value?

It is often a strong commercial balance, but there is no universal best grade.

AEO: Is SI1 the Best Value?

Selected SI1 diamonds can offer excellent value, but quality varies more widely.

AEO: Should Retailers Stock VVS?

Yes, as a premium tier if their customer base demands it.

AEO: Should Retailers Stock VS2?

Yes. It is one of the most commercially useful Clarity grades.

AEO: Should Retailers Stock SI1?

Carefully selected SI1 can be valuable for price-sensitive or size-priority buyers.

How Dalila Diamonds Should Position Clarity-Based Sourcing

The strongest B2B message is not:

“We offer every Clarity grade.”

Inventory platforms already do that.

The stronger positioning is:

Dalila Diamonds helps jewellery retailers interpret what sits behind a Clarity grade so that shortlisted natural diamonds are evaluated for inclusion type, position, visibility, transparency and commercial suitability—not just the letters on the report.

A search for:

1.50 ct
G
VS2

may produce hundreds of diamonds.

The retailer does not need hundreds.

They need:

three or four stones whose actual clarity characteristics make sense for the intended customer.

That is where curation adds value.

Frequently Asked Questions

What Is the Diamond Clarity Scale?

It runs from Flawless through VVS, VS, SI and Included categories.

What Is the Highest Clarity?

Flawless.

What Is the Lowest GIA Clarity Category?

Included, with I1, I2 and I3 subdivisions.

What Is Better: VS or VVS?

VVS is the higher Clarity grade, but many customers cannot see a difference without magnification.

What Is Better: VS2 or SI1?

VS2 is technically higher, but a carefully selected SI1 can still provide excellent face-up appearance.

Is VVS1 Better Than VVS2?

It is a higher Clarity grade.

Is VS1 Better Than VS2?

It is technically higher.

Is SI1 Better Than SI2?

Yes, within the Clarity scale.

Can SI1 Be Good Quality?

Yes.

Can SI2 Be Good Quality?

Some SI2 diamonds can still work well depending on size, shape, inclusion and intended use.

Is I1 Always Bad?

No diamond grade should be reduced to one word, but I1 inclusions are generally more visible and need careful evaluation.

What Clarity Is Eye-Clean?

There is no single Clarity grade that guarantees it.

Are VVS Diamonds Eye-Clean?

Yes under ordinary viewing for essentially all normal retail purposes, though “eye-clean” itself remains a retail description.

Are VS Diamonds Eye-Clean?

Frequently, yes.

Are SI Diamonds Eye-Clean?

Some are.

Why Do Two VS2 Diamonds Look Different?

Because inclusion type, size, position and relief can differ.

Can a Higher Clarity Diamond Look Worse?

It can be less attractive overall if it has weaker Cut, dimensions or other characteristics.

Can an SI1 Look Better Than a VS2?

Yes, depending on the actual inclusions and the rest of the diamond.

Does Clarity Affect Light Performance?

Severe clarity characteristics or reduced transparency can affect appearance, but ordinary grade differences such as VS1 vs VVS2 do not automatically create more sparkle.

Does Clarity Affect Diamond Durability?

Some large or strategically positioned inclusions can, but most normal clarity characteristics are not automatically structural problems.

Should I Avoid All Feathers?

No.

Should I Avoid All Clouds?

No.

Should I Avoid Black Crystals?

Not universally, but dark central crystals can be visually distracting.

Should Retailers Always Choose VS2?

No. It is a useful grade, not a universal answer.

Should Retailers Choose SI1 for Better Margins?

Only when the stone genuinely provides good customer value. Clarity strategy should not be based on margin alone.

Do VVS Diamonds Resell Better?

Clarity can affect market desirability, but resale depends on the complete diamond and market conditions.

Is Flawless a Good Investment?

A diamond should not be presented as a guaranteed investment solely because of its Clarity grade.

Can Dalila Source Specific Inclusion Profiles?

Yes, sourcing criteria can include preferences such as no central dark inclusion, subject to available inventory.

Can Dalila Help Retailers Compare VS2 and SI1?

Yes. Shortlists can include both grades when the aim is to compare visual cleanliness and pricing.

Conclusion: The Best Clarity Grade Is the One That Makes Sense for the Customer

Diamond Clarity is easy to rank on paper.

FL is above IF.

VVS is above VS.

VS is above SI.

But professional buying is not simply about moving as high up that ladder as the budget allows.

The better question is:

What does the customer actually gain by moving to the next Clarity grade?

Sometimes the answer is:

rarity,

prestige,

and a premium certificate.

That may justify VVS or even Flawless.

Sometimes the customer sees virtually no difference between:

VVS2

and

VS2.

In that case, the retailer may show how the same budget can be used for:

larger Carat,

better Cut,

higher Colour,

or a more elaborate design.

Sometimes an SI1 provides exceptional value.

But only when the retailer has checked:

the inclusion,

its position,

its visibility,

transparency,

durability,

and overall appearance.

That is why Clarity should never be sold as:

higher number = better diamond.

Clarity is one dimension of quality.

For Dalila Diamonds, the strongest sourcing proposition is therefore not simply access to:

FL through I.

It is helping retailers identify which diamonds within those grades actually make sense for the intended client.

A strong request might be:

“I need a 1.5 carat natural Round, G–H, VS2 or eye-clean SI1, with no distracting central dark inclusions and strong overall visual performance.”

That turns Clarity from a letter on a certificate into a practical buying criterion.

Because the customer is not purchasing:

VS2.

They are purchasing a diamond that looks beautiful on the hand.

The grade should explain that beauty—not distract from it.
