Frequently Asked Questions

Is New York a good city to sell diamonds in?
Absolutely. As the diamond capital of the U.S., New York offers a dense network of professional buyers, GIA-certified gemologists, and resale opportunities, especially within the Diamond District. This environment ensures better prices, transparent appraisals, and fast transactions.
What factors affect how much I can sell my diamond for?
The main factors are the 4 Cs—carat, cut, color, and clarity—as well as certification status (like GIA), market demand, and whether it’s a loose stone or set in jewelry. Buyers may also assess the brand or designer value if it’s part of a luxury piece.
Can I sell a diamond that’s been in my family for generations?
Yes, estate and vintage diamonds often carry historical or collectible value, especially if they feature antique cuts or are from well-known eras or brands. New York buyers experienced in estate jewelry can evaluate such pieces accordingly.
Will I get paid immediately for my diamond in New York?
Yes, most buyers offer same-day payments via cash, cheque, or wire transfer. After evaluation, if you accept the offer, payment is processed right away, and a receipt or documentation is provided for your records.
Should I clean my diamond before selling?
A clean diamond looks more brilliant and can present better under inspection. Gently clean it using mild soap and water, or let the buyer clean it before appraisal. While it won’t change the grading, it may help in getting a better offer.
