Carlos Peña Renis

Expert Asian Art & Objects / Jewellery

“Catawiki's auctions give me the opportunity to see different markets, styles and also trends.”

Carlos started in a jeweller’s as an apprentice and was working there for more than 15 years. Here, he learnt the profession and from the first moment, he felt that this was made for him. This experience and his different studies, have led him to become a professional gemmologist and a specialist in modern jewellery.

As soon as he saw the vacancy to work as an expert at Catawiki, he did not think twice about it. Since then, he tries to ensure that what appears in the descriptions and images of each lot is exactly what the buyer receives. In some cases, Carlos asks the seller for as many images as possible and for other cases, he utilises his own experience.

In order to guarantee the good quality of his auctions, Carlos focuses on the finishing of the pieces. ‘Catawiki's auctions give me the opportunity to see different markets, styles and trends,’ our expert says. He also loves the technological aspect of the company. According to Carlos, the Catawiki style takes jewellery out of the traditional and classical setting and combines it with technology.

With his extensive experience and knowledge, Carlos contributes considerably to the growth of the modern jewellery auctions, detecting at a glance and without any problems the good quality jewellery on which our potential buyers are interested.
