Our large turnover and many business contacts allows us to find the proper buyer for you at the right price. For this reason, you can sell your diamonds with confidence that you will receive the best possible payout for goods.
Experts in Both Uncertified & Certified Diamonds
We specialize in certified diamonds by the most trusted diamond grading companies in the world. Some of them for example include: GIA, HRD and IGI.
We are also GIA-certified graders with three generations of experience passed along in the field, but we both buy and sell diamonds that do not have certificates as well. Should you desire, we also deal with other certificate types on request.
