Diamond auctions with top quality

We auction exclusive, natural diamonds of the highest quality, certified by international authorities. From a variety of cuts to flawless stones: every diamond is assessed by experts.

Why choose our diamond auctions?

As one of the few auction houses in Europe, we organize exclusive diamond auctions several times a year, featuring only high-end natural diamonds.
All diamonds we auction are certified by the most renowned and reliable certification agencies in the diamond industry, including GIA, HRD, and IGI. From rare fancy colored diamonds to perfect colorless specimens with superior clarity, each piece is carefully selected and thoroughly inspected by our experts.
They assess the traditional 4 Cs (cut, color, clarity, and carat), authenticity, and origin. The combination of professional knowledge, experience, and our extensive international network makes us the ideal partner for buying and/or selling high-quality diamonds through auction.
