Frequently Asked Questions

How do I determine the value of my diamond before selling it in NYC?
The value of your diamond depends on multiple factors known as the 4 Cs—cut, color, clarity, and carat weight. In NYC, where the diamond market is vast and competitive, additional aspects such as certification (like GIA), fluorescence, and market demand are also considered. It’s highly recommended to have your diamond appraised by a professional gemologist who can provide a fair market estimate. Reputable buyers will evaluate your stone transparently and may even offer to verify it against official grading standards.
Is it safe to sell diamonds in New York City?
Yes, NYC is one of the safest and most active places in the world to sell diamonds, especially in renowned areas like the Diamond District. However, safety largely depends on whom you choose to sell to. Legitimate diamond buyers in the city will offer secure transactions, proper paperwork, and verifiable credentials. Avoid cash-only operations without contracts or appraisals. For peace of mind, always read reviews and check licenses before proceeding.
Do I need a GIA or AGS certificate to sell my diamond?
While a certificate from GIA, AGS, or other recognized institutions adds credibility and can help you secure a better price, it is not absolutely necessary. Many buyers in NYC accept uncertified diamonds and conduct their own assessments. However, without a certificate, the evaluation becomes subjective, and the final offer may be slightly lower. If you’re unsure, some buyers offer in-house grading or may suggest sending the stone for certification before finalizing the sale.
What types of diamonds are in highest demand among NYC buyers?
Round brilliant cut diamonds generally remain in highest demand due to their classic appeal and brilliance. Stones ranging from 1 to 2 carats, with decent color (G-H) and clarity (VS1-VS2), tend to sell the fastest. Fancy shapes like ovals and cushions are also becoming more popular. Regardless of shape, certified diamonds with minimal inclusions and strong light performance typically attract the best offers from NYC buyers.
Can I sell a chipped or damaged diamond in NYC?
Yes, even chipped or damaged diamonds have value, especially in NYC’s secondary market. While you might not receive the same price as an intact stone, many buyers consider the resale potential or the diamond's suitability for re-cutting. Be upfront about any flaws and consult a buyer who has experience dealing with estate or recycled diamonds—they can still make you a fair offer based on the stone’s salvageable qualities.
