About Sell Diamonds NYC

NYC's Original Diamond Buyer

Sell Diamonds NYC was founded in the New York Diamond District — the world's most concentrated diamond marketplace — over three decades ago. We have built our reputation on one principle: pay sellers exactly what their diamonds are worth, every single time.

Unlike pawn shops, jewelry chains, or online mail-in services, we are specialists. Our buyers hold GIA-recognized credentials and have evaluated thousands of diamonds across every grade, shape, and origin. We don't guess — we assess.

We also buy gold, silver, platinum, estate jewelry, and luxury watches, making us the single most convenient destination to liquidate a fine jewelry collection in New York.
