'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 Natural history auction

Natural History is concerned with the observational study and research of organisms such as animals, plants and fungi in their environment. The field gained prominence thanks to the work of 19th Century naturalists such as Alfred Wallace, Henry Bates and Charles Darwin. These pioneers travelled across the world collecting numerous specimens, the study of which helped to form some of the most pervasive theories in existence today - such as Charles Darwin’s theory of evolution.

Whether you wish to sell a fossilised Mammoth bone; a piece of meteorite; a prehistoric insect preserved in amber or a rare and precious mineral or gemstone - Catawiki has an auction suitable for your item. With some Natural History items commanding a high price, it is important that both sellers and buyers have peace of mind when participating in one of our auctions. That’s why our expert auctioneers supervise the auction process, while our notary officials work to ensure the validity of any bids placed. Once you’ve sold your item, you’ll want to know that payment will be processed securely, and that your buyer will be kept happy throughout the process. Our secure payment system keeps your money safe and your buyer satisfied.
