How are diamond prices determined in the East Bay?

(January 2026 Update)

We value diamonds based on the global 2026 Rapaport Price List, prioritizing natural stones over 1.00 carat with GIA certification. While the market for lab-grown diamonds has softened, natural diamonds—especially Round Brilliants and antique Old European cuts—retain strong resale liquidity. We use ASET and loupe analysis to verify cut quality, ensuring you receive a fair offer based on current wholesale trading prices, not low-ball pawn offers.

Do you buy Lab-Grown Diamonds?

The secondary market for lab-grown diamonds has dropped significantly in 2026. While we focus on Natural Earth-Mined Diamonds, we can provide liquidation offers for high-quality lab stones on a case-by-case basis.
