What Makes Catawiki the Place to Sell Extraordinary Items?

You might think “It will never happen to me!” until one day, rummaging in an old box you discover a first edition book from the 1800s or - perhaps as one fisherman recently made the news with - the world’s largest pearl under your bed! At that point you think “What on earth can I do with this?”

Using the auction

Diamond is the most fascinating material that I know. No one stone is the same.

Mark van Keuk came into contact with diamonds when he started his degree in goldsmithing, inspired by his brother. He soon noticed his passion for the profession and for diamonds which fascinated him to no end. After his education, he started working as a diamond setter at a large diamond dealer in Amsterdam. After twelve years, he became a buyer and spent a lot of time in Antwerp. In this centre for diamond trade he acquired many international contacts and has assessed thousands of diamonds.

After all these years of experience, Mark van Keuk is the appointed auctioneer for the diamond auction. He knows what's happening in the market and he knows the requirements diamonds need to meet. He examines each diamond and its accompanying certificates thoroughly before approving them for his auctions. His previous work experience has enabled Mark van Keuk to effortlessly compose interesting auctions. He likes to guide the buyers by answering questions and erasing their doubts. This way, every diamond enthusiast can bid on his auctions with confidence.
