Introducing Origins

A diamond with
nothing to hide.

Our Story

Over a century in the heart of the diamond world.

Four generations of one family at the center of New York's diamond trade. The Exchange was established in 1979 — but the relationships, the knowledge, and the standard of trust go back to 1917.

1917

A family enters the diamond trade

The founding generation of our family establishes itself in New York's emerging diamond district, building relationships with cutters, traders, and manufacturers that would span four generations and over a century.

1979

The New York Diamond Exchange is established

The New York Diamond Exchange is formally founded — and immediately makes history by becoming the first company to publish diamond prices for public use, as noted in The Wall Street Transcript. A market that had always been opaque was opened to everyone.

1980s

The press takes notice

The New York Diamond Exchange is quoted in the NY Times, The Wall Street Journal, USA Today, and the New York Post — becoming the trusted public voice on diamond valuation, market pricing, and consumer transparency.

Today

In the entire history of The New York Diamond Exchange, no complaint has ever been filed against us. Not one. That record is the result of a commitment to transparency, personal service, and fair dealing that has defined this family from the very beginning.

about The New York Diamond Exchange.

We are located on 47th Street in New York City — in the heart of the Diamond District. Our office operates by appointment only, and we proudly serve customers across the entire United States. You don't need to be in New York to receive New York market prices. We've worked with clients from Chicago, Los Angeles, Miami, Seattle, San Francisco, and everywhere in between through our secure insured mail service.

Start with a phone call or our online inquiry form. We'll discuss your item and give you a preliminary estimate. New York area customers can schedule a private appointment — our gemologist evaluates your piece while you wait, and we make a cash offer on the spot. Payment is immediate. Out-of-state customers can ship jewelry to us insured; we complete evaluation within one business day and make a written offer within two. Payment is made by check or Federal Wire transfer. All transactions are completely confidential — we never share your information.

We buy loose diamonds (0.70 carats and above), diamond engagement rings, diamond jewelry, and estate jewelry of all periods — including Georgian, Victorian, Art Nouveau, and Art Deco. We pay premium prices for designer pieces from Tiffany, Cartier, Harry Winston, and Van Cleef & Arpels. We also purchase gemstones, signature pieces, and entire estate collections. Whether you're an individual, bank, trust, or attorney, we're able to assist. If you're not sure whether we'd be interested in a piece, just ask — there's no obligation.

A local jeweler can only offer you what their local market will support. We are positioned at the center of the world's largest and most liquid diamond market — New York's 47th Street Diamond District. Our daily contact with manufacturers, traders, and international buyers means your diamond gets exposure to the widest possible pool of demand. This translates directly into a higher offer for you. We've been operating this way since 1979, and our family's 107+ years of industry relationships are the reason we can consistently offer more than local markets.

Yes — we sell only GIA-certified diamonds. The GIA (Gemological Institute of America) grading report gives you an objective, independent assessment of your diamond's cut, color, clarity, and carat weight. We also provide a co-certification by EGL or IGI at no additional cost to independently verify the GIA grading. Every diamond we recommend to a customer is personally inspected by our team before we send it — which is why over 99.9% of customers keep their diamonds.

We offer a 7-day unconditional return guarantee — in writing. When you receive your diamond, you have seven days to inspect it in your own home and compare it to the GIA certificate. If for any reason you are not satisfied, return it within seven days for a full refund, no questions asked. This guarantee has been in place for over 24 years. Our 99.9%+ keep rate is a direct result of our personal inspection process — we only recommend diamonds we would be proud to own ourselves.

Origins is the lab-grown diamond brand of The New York Diamond Exchange. Origins diamonds are created in a controlled environment and are physically, chemically, and optically identical to mined diamonds — the same carbon crystal structure, the same fire and brilliance, graded by the same GIA standards. The difference is what's not in the equation: no land disturbed, no communities displaced, and a clear chain-of-custody from creation to certification. Origins diamonds are also significantly lower in price per carat than comparable mined stones — because the true cost of mining is no longer baked in.

The New York Diamond Exchange was formally established in 1979 — and in that same year, we became the first company in the United States to publish diamond prices for public use, a milestone noted in The Wall Street Transcript and cited in The New York Times, The Wall Street Journal, USA Today, and the New York Post. The family behind The New York Diamond Exchange has been continuously active in the New York diamond industry since 1917 — over 107 years of unbroken presence in the same market. In the entire history of The New York Diamond Exchange, no complaint has ever been filed against us. That record exists because we have always operated the same way: transparently, personally, and with the buyer's or seller's best interest genuinely in mind.
