Where Trust Shines, And Quality Sparkles
SYD — Sell Your Diamond
SELL YOUR DIAMOND IN ANTWERP
Receive a confidential preliminary estimate for a loose natural diamond, diamond ring or eligible diamond jewellery. Submit the details you know, upload clear photographs and add the grading-report number if one is available. Our Antwerp team will review the information and explain the next step before any physical handover is arranged.
A preliminary estimate is based on the information supplied online. A final offer can only be made after the diamond or jewellery has been physically examined and its details verified.
SELL YOUR DIAMOND IN ANTWERP
You can submit your natural diamond or diamond jewellery directly to an experienced diamond buyer in Antwerp. Begin by sharing the carat weight, shape, colour, clarity, grading report and photographs you have. After an initial review, eligible items can proceed to a private in-person assessment or, where available, an approved secure collection.
The final selling price depends on the diamond itself—not simply the original receipt, an insurance replacement figure or a generic online calculator. The diamond’s identity, 4Cs, proportions, fluorescence, condition, documentation and current secondary-market demand all affect the offer.
The service is designed for private sellers, families, collectors and trade contacts who want an informed review of:
If the item has no grading report, is mounted, contains coloured gemstones, has been treated or may be laboratory-grown, provide that information in the form. The team can confirm whether it is suitable for further assessment before you arrange a visit or shipment.
FIVE CLEAR STEPS
Step 1
Complete the short estimate form with the information you know. Useful details include the item type, diamond shape, carat weight, colour, clarity, measurements, fluorescence and whether the stone is loose or mounted.
You do not need to guess missing grades. If you are unsure, select “unknown” and upload clear photographs instead.
Step 2
Upload a face-up photograph, a side view and a clear image or PDF of any GIA, IGI or HRD report. You can also enter the report number so the document can be checked against the information supplied.
Photographs help with the first review, but they cannot establish a final grade, confirm every treatment or replace physical examination.
Step 3
The submitted details are reviewed to establish whether the diamond fits the service and what information is still needed. You will then receive guidance on the next step and, where possible, a preliminary estimate range.
This stage should be described as an estimate rather than a binding offer because photography, mounting and incomplete documentation can conceal characteristics that affect value.
Step 4
Eligible diamonds can be examined during a private appointment in Antwerp. Depending on the item, location and insurance eligibility, a secure collection may also be arranged after the preliminary review.
Do not send a diamond or jewellery until the collection method, insurance limits, packaging requirements, identity checks and return terms have been confirmed in writing.
Step 5
After physical verification, you receive a clear final offer based on the assessed diamond, its documentation, condition and current market demand. The offer should also explain whether the metal or additional stones have been included.
If you accept, payment is made by secure bank transfer after the required ownership, identity and banking checks are completed. The precise payment timing should be stated in the final offer.
A professional diamond evaluation considers more than carat weight.
WHAT AFFECTS YOUR OFFER?
The evaluator must establish whether the stone is natural or laboratory-grown and identify any known colour or clarity treatments. These characteristics can materially change market value.
Carat is the diamond’s weight. Measurements show its actual length, width and depth and help identify whether weight is distributed attractively or hidden below the setting.
Colour and clarity are checked against recognised grading standards. Inclusion type, position, visibility and possible durability concerns can matter beyond the headline grade.
Shape affects market demand, while cut quality, proportions, polish and symmetry influence appearance. Fancy shapes also require visual checks for outline, bow tie, dark areas and face-up spread.
Fluorescence may influence marketability depending on its strength, colour and effect on appearance. Transparency, haziness and light performance are also assessed directly.
A GIA, IGI or HRD report can support identification and provide an established description of the stone. The report number, measurements and any laser inscription should correspond with the submitted diamond.
Chips, abrasions, damage, previous repolishing, loose settings and wear may affect the assessment. For mounted jewellery, the metal, craftsmanship and additional stones may be considered separately.
An insurance replacement value, original retail price and current selling value answer different questions. GIA’s consumer guidance explains that fair-market assessment considers quality, availability and local desirability. The final offer therefore reflects the current market for the specific item, not simply what it originally cost.
EXPERT PHYSICAL REVIEW
Antwerp is a major centre for natural-diamond expertise and trade. A direct assessment gives the evaluator access to current market information and allows the diamond to be examined as an individual stone rather than valued from a photograph or generic price chart alone.
With Dalila Diamonds, the process is designed around:
No responsible buyer can determine a final diamond value from one photograph. The purpose of the online form is to establish a useful starting point and avoid unnecessary travel or shipping before the item has been reviewed.
Providing complete information can make the initial review faster. Prepare:
Clean only with a safe, gentle method before taking photographs. Do not remove a stone from its setting or attempt to test it at home.
You can still submit an enquiry when a grading report is missing. Choose “No report” or “Unknown”, upload the best photographs available and explain what you know about the item.
The team can then decide whether the diamond is suitable for physical evaluation and whether an independent laboratory report or other verification may be useful. Not every uncertified item will necessarily be eligible for purchase.
VISIT OR REQUEST COLLECTION
Sellers who can visit Antwerp may arrange a private assessment at Dalila Diamonds, Hoveniersstraat 30, 2018 Antwerp, Belgium. Appointment confirmation should be required before arrival so the appropriate specialist and equipment are available.
For sellers elsewhere in Europe, collection availability should be confirmed after the initial review. Insurance limits, courier identity, packaging, ownership documents, delivery tracking and return conditions must be provided in writing before the item leaves the seller’s control.
You can submit the diamond to an experienced Antwerp buyer for a preliminary review followed by physical evaluation. Compare the process, documentation, insurance terms and final written offer before accepting a sale.
Yes, eligible natural-diamond rings can be submitted for review. The diamond and the setting may be assessed separately so you understand what has been included in the final offer.
Loose natural diamonds can be submitted with their carat weight, shape, grades, measurements, photographs and grading-report details. Acceptance depends on physical verification and current buying requirements.
You may submit an enquiry without a certificate. Upload clear photographs and select “No report” or “Unknown”. The team will confirm whether physical evaluation or additional documentation is needed.
Yes, GIA, IGI and HRD report details can be included with the submission. The report number and diamond characteristics are checked during evaluation.
The assessment considers natural origin, treatments, carat, colour, clarity, shape, cut quality, fluorescence, transparency, condition, documentation and current secondary-market demand.
The current service offers a free initial estimate based on submitted information. The estimate is not a binding final offer and remains subject to physical examination.
An in-person private evaluation is available in Antwerp. Depending on the item, seller location and insurance eligibility, an approved secure collection may be available after preliminary review.
When a collection is approved, the courier, insurance limit, packaging process, tracking and return terms should be confirmed in writing before the item is released.
Payment timing is confirmed with the final offer. After acceptance and completion of required identity, ownership and banking checks, payment is made by secure bank transfer.
An insurance valuation estimates replacement cost, while a buyer’s offer reflects the item’s current secondary-market demand, condition and resale route. They are different valuation purposes and should not be expected to match.
Upload a sharp face-up image, a side view, the complete jewellery item and close-ups of any damage or markings. Use neutral daylight and a plain background without applying filters.
Submit the information you know and upload clear photographs of the diamond, jewellery and grading report. The first review will determine whether the item is suitable and explain the safest next step.
Do not ship or hand over a diamond until the evaluation method, insurance, identification requirements and written terms have been confirmed.
