A client sits in a quiet showroom in London, reviewing a selection of diamonds under soft lighting. Several brilliant cuts sparkle intensely, throwing flashes of light across the table. But then something different appears—quieter, more refined, almost architectural in its presence.

It doesn’t sparkle in the same way. It reflects.

“I like this one,” the client says, pointing to an emerald cut. “It feels… cleaner.”

For jewelry retailers and bespoke designers across the US and Europe, this reaction is becoming more common. In a market long dominated by brilliance and sparkle, a new appreciation is emerging for restraint, clarity, and precision.

This is the return of step-cut diamonds—specifically emerald and Asscher cuts. These shapes are not driven by trend cycles alone; they are rooted in design history, craftsmanship, and a different definition of beauty.

What Are Step-Cut Diamonds?

Step-cut diamonds differ fundamentally from brilliant-cut diamonds in how they are faceted.

Instead of the triangular facets designed to maximize sparkle, step cuts feature long, rectangular facets arranged in parallel lines. These facets create a reflective effect often described as a hall-of-mirrors appearance.

The two most recognized step-cut shapes are:

• Emerald cut

• Asscher cut

Both emphasize clarity and symmetry over intense brilliance. They do not attempt to overwhelm with sparkle—instead, they reveal the internal structure of the diamond in a more transparent way.

 Why Emerald Cut Diamonds Are Back in Demand

Emerald cut diamonds have seen a strong resurgence in 2026, particularly among design-conscious buyers and high-end clientele.

Part of this appeal comes from their association with elegance and understatement. Unlike round or brilliant cuts, emerald cuts do not rely on excessive sparkle to make an impression. Their beauty lies in proportion, balance, and clarity.

They also carry a strong connection to Art Deco design, a style that continues to influence modern jewelry. Clean lines, geometric forms, and architectural precision all align with current design trends, making emerald cuts feel both vintage and contemporary at the same time.

This combination makes them particularly attractive to clients who want something timeless but not predictable.

The Asscher Cut — Precision in Symmetry

The Asscher cut shares many characteristics with the emerald cut but introduces a more square shape and a deeper pavilion. This creates a more concentrated visual effect, often described as more “layered” compared to the elongated emerald cut.

One of the defining features of the Asscher cut is its symmetry. When properly cut, it produces a balanced, almost hypnotic pattern of reflections that draws the eye inward.

For retailers, Asscher cuts appeal to clients who appreciate precision and detail. They are less common than emerald cuts, which adds to their exclusivity.

Why Clarity Matters More in Step Cuts

One of the most important differences between step-cut and brilliant-cut diamonds is how they handle inclusions.

Because step cuts have large, open facets, they do not hide imperfections as effectively. In brilliant cuts, the intense sparkle can mask minor inclusions, making them less noticeable.

In step cuts, however, the transparency of the design means that inclusions are more visible.

This is why clarity becomes more critical. Retailers often prioritize higher clarity grades when sourcing emerald and Asscher diamonds to ensure a clean, refined appearance.

For trade professionals, this is not about chasing perfection—it is about maintaining the visual integrity of the stone.

 The Role of Color in Step-Cut Diamonds

Color also plays a more prominent role in step-cut diamonds.

Because of their open facet structure, any hint of color can be more noticeable compared to brilliant cuts. This means that higher color grades are often preferred, particularly in white metal settings.

However, this does not mean lower color grades should be avoided entirely. In certain designs, especially those using yellow or rose gold, slightly warmer tones can complement the overall aesthetic.

For wholesale buyers, the key is understanding how color interacts with both the cut and the final setting.

Light Performance — Subtle, Not Flashy

Step-cut diamonds do not produce the same level of sparkle as brilliant cuts, and that is intentional.

Instead of focusing on fire and scintillation, they emphasize:

• Broad flashes of light

• Clean reflections

• Depth and structure

This creates a more understated form of beauty that appeals to clients who prefer refinement over intensity.

For retailers, this requires a shift in how diamonds are presented. The selling point is not how much a diamond sparkles, but how it reflects light in a controlled and elegant way.

Sourcing Challenges in Step-Cut Diamonds

Sourcing high-quality emerald and Asscher diamonds can be more challenging than sourcing round diamonds.

Because these shapes require precise proportions and high clarity, there is less room for compromise. Stones that do not meet these standards can appear flat or lifeless.

Additionally, supply is more limited, particularly for larger stones with strong specifications.

For wholesale buyers, this makes trusted sourcing relationships essential. It also creates an opportunity to differentiate inventory by offering stones that are harder to find.

Step-Cut Diamonds in High-End Jewelry

Emerald and Asscher cuts are often associated with high-end and bespoke jewelry.

They are frequently used in:

• Solitaire engagement rings

• Art Deco-inspired designs

• Minimalist settings that emphasize the stone itself

Their clean lines and structured appearance make them ideal for clients who value design as much as the diamond itself.

High-profile figures like Beyoncé and Amal Clooney have also contributed to their visibility, reinforcing their association with sophistication and modern luxury.

Inventory Strategy for Retailers

For retailers, step-cut diamonds should be positioned as a premium, design-led category.

Rather than carrying large volumes, it is often more effective to:

• Stock carefully selected high-quality stones

• Focus on clarity and proportion

• Pair with strong design storytelling

This approach aligns with the expectations of clients who are drawn to these shapes.

Conclusion

Their resurgence in 2026 reflects a broader shift in the market, where customers are increasingly drawn to designs that feel intentional and distinctive.
