Important: Real Lab Diamonds Only
We buy genuine lab-created diamonds (CVD and HPHT process stones) — diamonds that are chemically and physically identical to natural diamonds, just grown in a laboratory. We do NOT buy cubic zirconia, moissanite, or other simulants. If you're unsure what you have, call us and we'll help you identify it.
We Buy GIA & IGI Certified Lab Diamonds
Whether you have a loose lab diamond or one set in jewelry, we evaluate it fairly using current secondary market wholesale prices.
CVD & HPHT Diamonds
Both Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT) lab diamonds are accepted. We verify authenticity using professional equipment.

The Resale Market for Lab-Grown Diamonds
Lab-grown diamond prices have decreased as production technology improves. The resale value is typically lower than natural diamonds, but a strong secondary market exists. As specialist buyers, we stay current with market pricing and offer some of the most competitive prices in Tampa Bay for lab-created stones.
If your lab diamond is set in gold or platinum jewelry, we evaluate both components — giving you a combined offer that accounts for the full value of your piece.
