How We Value Your Diamond
The 4 Cs — What Determines Your Diamond’s Value
Every diamond is evaluated on four internationally recognized criteria. Our GIA-trained gemologists assess all four in front of you — no black box, no guesswork.
Cut The most important factor. Determines how light travels through the stone — from Excellent to Poor. Ideal/Excellent cuts maximize brilliance and command the highest prices.
Color Graded D (colorless) to Z (light yellow). D–F are most valuable. Fancy colored diamonds — pink, blue, yellow — are evaluated separately and can carry extraordinary premiums.
Clarity Measures internal inclusions and surface blemishes on a scale from FL (Flawless) to I3. Eye-clean SI1/SI2 stones are the sweet spot for value. FL/IF stones carry significant premiums.
Carat Weight measured in carats (1ct = 0.2g). Value increases non-linearly — a 2ct stone is worth more than 2x a 1ct stone of equal quality. Magic sizes (1ct, 2ct, 3ct) command premiums.
What We Buy
Every Type of Diamond. Any Size, Any Condition.
From a modest quarter-carat to a museum-quality 10+ carat stone, we evaluate and purchase all diamonds with the same professional care.

Signed designer pieces (Cartier, Tiffany, Van Cleef) evaluated for brand premium. 📈 Fancy Colored Diamonds Pink, blue, yellow, green, red. Natural fancy colored diamonds can be extraordinarily valuable — we assess origin and intensity. 🌟 Rare & Large Stones 3ct, 5ct, 10ct and beyond. D color, flawless, exceptional makes. We have buyers for significant individual stones. 💣 Diamond Parcel Lots Multiple stones, mixed sizes and qualities. Melee diamonds, calibrated rounds, trade parcels. Any quantity welcome.

“I brought in my ex’s engagement ring not sure what to expect. The gemologist took time to explain the grading, showed me exactly what they were looking at, and gave me an offer well above what I got quoted online. No pressure, professional, and I walked out with cash. Highly recommend.”

The Diamond Selling Guide
What You Need to Know Before Selling a Diamond in NYC
Selling a diamond is fundamentally different from selling gold or silver. Precious metals have a universal spot price — a gram of 14k gold has the same value everywhere. Diamonds do not. Each stone is unique, graded on multiple subjective and objective criteria, and valued based on current buyer demand in a market that shifts constantly.
Does a GIA Certificate Help?
Significantly. A GIA (Gemological Institute of America) grading report is the most trusted and widely recognized diamond certificate in the world. Certified stones are easier to value accurately and easier to resell, which means buyers will pay more for them. If you have a GIA certificate, bring it — it will improve your offer. If you don’t have one, we grade the stone ourselves and make an offer based on our professional assessment.
How Do Diamond Prices Compare to Retail?
Retail jewelry stores mark up diamonds substantially — 50% to 100% or more above wholesale value is common. When you sell back to a buyer, you are selling at wholesale, not retail. This is true everywhere, not just at our office. The key is finding a buyer who pays the highest possible wholesale price, which requires expertise and current market knowledge — both of which we have.
What About Fancy Colored Diamonds?
Natural fancy colored diamonds — pink, blue, green, orange, red — are among the rarest objects on Earth and can be extraordinarily valuable far beyond what white diamonds command. A 1ct natural pink diamond can be worth 10-50x a comparable white diamond. We have expertise in fancy colored stones and connections to specialized buyers for significant pieces.
Should I Get an Appraisal Before Selling?
A retail appraisal (the number your insurance company uses) reflects replacement cost at retail prices — typically 2-3x what you would actually receive when selling. It is not an accurate guide to resale value. We provide our own professional evaluation at no charge, and we are happy to walk you through our grading so you understand exactly what your diamond is worth in today’s actual market.
Selling an Engagement Ring After a Breakup or Divorce
This is one of the most common situations we handle. We treat every client with complete privacy and discretion. There is no judgment, no awkward questions — just a professional, honest evaluation and a fair cash offer. Most people are surprised by how straightforward and fast the process is. Many walk in uncertain and walk out relieved.
FAQ
Common Questions About Selling Diamonds in NYC
No — a certificate is not required. We grade the stone ourselves. However, a GIA certificate does improve your offer because it confirms the grading and makes the stone easier to resell. Bring it if you have it.
Our GIA-trained gemologist evaluates cut quality, color grade (D–Z scale), clarity grade (FL to I3), and carat weight — all in front of you. We explain every factor and show you what we’re seeing. No black box.
No buyer anywhere pays retail value for a used diamond. Retail represents the store’s markup over wholesale cost. We pay the highest possible wholesale price, which is the true resale market value of your stone.
Yes, but lab-grown diamonds have significantly lower resale value than natural diamonds due to rapidly declining production costs. We buy them but at lower prices than natural stones of comparable grade.
Same day. Accept the offer and receive cash immediately. Most evaluations take 10–15 minutes for standard pieces. Larger or more complex stones may take slightly longer for thorough assessment.
Yes. We assess the diamond and the metal setting separately and pay for both. A platinum or 18k gold engagement ring setting has meaningful scrap metal value in addition to the diamond.
