Cash for Diamonds in Boston
Diamonds are worth real money when the buyer actually knows stones. At LBC Pawn, diamonds are evaluated at the counter by people who grade and buy them every day — loose stones, engagement rings, earrings, tennis bracelets — and priced against the live wholesale market, not a pawn-shop guess.

How diamond buying works here
Bring it in — we test and price it at the counter in front of you, against live market prices. One strong cash offer, paid the same day. The more complete it is (box, papers, accessories, chargers), the more it pays — and the more you bring, the more you get. Not sure it qualifies? Text a photo first: 857-867-6468.
Papers and certifications (GIA, AGS, EGL) help and pay more, but they are not required — we test and verify stones in-house before any money moves. Big stones and full sets get our private VIP room (loans and transactions over $2,000).
Questions we hear
- Do I need a certificate to sell my diamond?
- No. A GIA or other certificate can help the price, but we evaluate uncertified stones at the counter every day. Bring whatever paperwork you have — and if you have none, come anyway.
- How much is my diamond worth?
- It rides on size, cut, color, and clarity against today’s wholesale market. Text a photo to 857-867-6468 for a ballpark, then bring it in for the exact number.
- Can I pawn my diamond instead of selling?
- Yes — borrow against it at 3% per month with no credit check, and get it back when you repay. First loan free up to $500.
