'Catawiki reaches exactly the right target audience I'm looking for. This is extremely beneficial for me. I started out small, but now I can live from the sales I make on Catawiki.'
Seller: Anything Else
'Spanish art is appreciated much more than we thought it would be abroad. We really had no idea about the international market until we joined Catawiki.'
Seller: El Testamento de Baron
The global stage that Catawiki provides is extremely attractive as it cuts out the astronomical costs associated with traditional auction houses and art galleries and helps me promote and sell my work on a large scale.'

About Catawiki's Gemstone auction

Gemstones are precious or semi-precious pieces of mineral crystal, which are polished and cut to produce a visually attractive and sought-after object. Gemstones are formed beneath the earth’s surface, as water interacts with minerals, to form solutions which are then subjected to formative factors such as heat and pressure. Varying greatly in value and desirability, gemstones have traditionally been associated with months of the year. These birthstones include Amethyst, for those born in February; Diamond for April births and Topaz or Pearl for those born in November. Among the most valuable gemstones are Diamonds and Rubies, however these are comparatively numerous when compared to extremely rare and far more valuable stones such as Painite, long considered one of the world’s rarest gemstones, valued between $50,000-60,000 per carat.

Catawiki’s Gemstone auctions include a wide range of precious objects such as Rubies, Sapphires, Amethysts, Emeralds and Opals. Lots in the Gemstone auctions vary in colour; number of carats; size; quantity and shape. Whether you have an extremely rare Diamond or a small, but perfectly formed Opal to sell, Catawiki’s Gemstone auctions are the ideal place to sell your special object. Our expert auctioneers supervise our auctions, while our notary officials work to guarantee the validity of bids placed. Once the bidding has ended, our secure payment system will make sure that your buyer is completely satisfied with their purchase.
