About Our Diamond Buying Process
Diamonds are the most subjective of the items we buy — two stones can look identical to the naked eye but have very different values based on cut quality, color grade, clarity, and carat weight. At The Precious Metals Group, our gemologists use professional loupe magnification, color comparison stones, and electronic testers to evaluate every stone carefully and arrive at a fair market offer.
We're located in the Diamond District — the center of the diamond trade in the United States — which means we have direct access to the market and can offer strong prices that reflect current diamond market conditions, not retail store buyback rates.
Have a GIA or AGS certificate? Bring it — it's helpful and can support a stronger offer. Don't have paperwork? That's fine too. We evaluate every stone independently and explain our assessment to you so you understand exactly what you have.

This is the most common question we get, and it deserves an honest answer. When you buy a diamond ring from a retailer, you're paying retail price — which includes the store's markup, overhead, and profit margin. When you sell, you're selling at secondary market value, which is lower. This is true across all luxury goods — it's not specific to diamonds or to us. What we offer reflects what the stone is genuinely worth in today's market, not what a retailer charged to sell it.
Yes. A GIA certificate provides independent verification of the stone's grades (cut, color, clarity, carat) and confirms it's a natural diamond. This gives us and you a reliable reference point and can support a stronger offer. If you have a GIA cert, bring it. If you don't, we evaluate the stone ourselves — it just takes a bit more time.
Yes. You don't need to have the stone removed before coming in. We can evaluate diamonds while they're set and make an offer on the full piece — diamond plus the metal (gold, platinum, etc.). We'll tell you the breakdown so you understand what each component contributes to the offer.
We buy diamonds of all sizes — from small accent stones to large center stones. Smaller diamonds (under 0.5 carat) have less individual value but still contribute to the total offer, especially in larger jewelry pieces with multiple stones. We don't have a minimum size requirement.
Very common. We see this every week. People come in after a divorce, an estate, or simply because they have a ring they'll never wear again and would rather have cash. There's no awkwardness here — we've helped hundreds of people in exactly that situation and we handle every transaction with complete discretion and professionalism.
