Diamonds are forever
In Catawiki's diamond auctions you can find diamonds in different shapes, colours and sizes. Every Diamond auction is curated by a team of dedicated experts who all specialise in the field of diamonds. Our auctions offer something for everyone, from lots of mixed diamonds, to fancy natural colour diamonds, and some auctions feature only diamonds without reserve prices!

The diamonds in our auctions have been certificated by laboratories such as GIA, HRD, IGI, EGL (US), IGE, EGL ( B ), IGL, AIG, CISGEM, GIL, NEL and AnchorCert. Every certificate has its own standard of grading diamonds which are always led by the 4 C's - Carat, Cut, Colour, Clarity.
