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?”

Taletta Janson

Auctioneer Gemstones

I sometimes can’t believe how beautiful the gems on offer are.

  • Studied Art History
  • Worked for several auction houses
  • Gemmologist graduate
  • Set up business with her own handmade jewellery
Taletta Janson

A love of auctions is in Taletta Janson’s blood. Her mother worked for an art auction and she became hooked when she went to help as a Saturday job. She discovered all the tension and dynamics associated with auctions and quickly realised this was where she wanted to work.

That was why Taletta decided to study art history: It was her ticket to the auction world. At least until she’d finished her studies, when she remembered another childhood passion: gemstones. She had to work with these precious stones somehow, so she focused on studying gemmology at the English Gemmological Association. Using all the knowledge and skills she acquired, she set up her own handmade jewellery company. Then she came across Catawiki.

Taletta knows that an auctioneer can provide major added value to the gemstone auction. With her knowledge and trained eye, she knows all the qualities that make the difference between a pretty stone and a masterpiece. Taletta loves to come across a beautiful ruby or tanzanite, but also hopes to include more expensive variants of lesser-known gems in her auctions, such as a brilliant tourmaline or spinel, together with an official gemmological report!

Auctioneer Gemstones

It’s fantastic how gems are associated with so many aspects of our culture.

  • 30 years' experience in gemmology
  • Studied gemmology with several follow-up studies
  • Had her own appraisal business
  • Worked as a teacher, an appraiser and in the international jewellery trade
Deborah Mazza

Deborah Mazza has always been interested in gems, but she only thought of making a career of it when a local professor gave a seminar on evaluating gemstones. Pretending to be 16 to get in, Deborah decided that this is what she wanted to do. Without hesitation, she chose to study gemmology in Germany and took further courses to continue her education. Deborah has worked with gems her whole life, as an appraiser, and also as a sales manager for large international companies such as Idar-Oberstein in Germany, one of the major centres for gemstone trading in the world. She knows the world of gemstones and jewellery through and through.

Over her lifetime Deborah has assessed thousands of gems and pieces of jewellery. Thanks to this experience she is able to assess these same items for Catawiki based on photographs. If there is any doubt, she consults her colleagues and always requests a certificate of authenticity. Deborah believes that one of her main responsibilities is ensuring that her auctions are put together well and are correct down to the last detail. In fact, she herself is a real gem as Catawiki continues to expand internationally.

Auctioneer Gemstones / Watches

My experience as a goldsmith helps me with evaluating watches.

  • Has been a watch enthusiast for more than 25 years
  • Almost 20 years' experience as a goldsmith
  • Owns his own goldsmith business
Joaquin  Fernandez Cebrian

Although Joaquin Fernandez Cebrian has always loved watches, his passion for watches really started during a tennis tournament that he took part in. Breitling, the famous watch manufacturer, hosted a small exhibition at the tournament with the newest models. It was love at first sight for the young Joaquin as he started saving money for his first Breitling. Since then he has been a real watch fanatic, keeping informed on all the new trends in the watch industry, takes part in fairs and regularly meets up with other enthusiasts. Unlike most enthusiasts, Joaquin Fernandez Cebrian doesn't like showing off his watches. He prefers keeping them discrete. According to Joaquin, this discretion doesn't apply to the watches at Catawiki; these need to be as well-presented as possible. He therefore regularly advises sellers on how to make good photos, on cleaning watches properly and giving the right information. This way the bidder knows exactly what he or she is bidding on and the seller ultimately gets higher revenues. Thanks to his experience as a goldsmith, Joaquin Fernandez Cebrian is able to evaluate the quality of golden watches and watches with inlaid jewels correctly. He loves doing this because each week he finds it incredibly exciting to see which beautiful watches are on offer.

An object becomes even more beautiful when you know the story behind it.

  • Doctor of Arts and Culture
  • Art teacher
  • Set up own jewellery trade
Christine Barrat

Christine Barrat is like a modern day Indiana Jones. Always looking for adventure, and hunting for new treasures and experiences throughout Europe and Asia. Not surprising, given her childhood surrounded by collectors and artistic family members. They brought the craziest things home that they acquired during their travels, from mummified cats to strange stones. As a 10-year-old girl, she spent hours examining the stones under a microscope with her brother, who has become a renowned geochemist. Christine took the artistic route and paid for her studies by selling gems and antiques that she’d found at markets. She used these skills to train to become a Doctor of Arts and Culture. She crossed all of Europe and much of the world for her work developing art programmes. She also set up her own jewellery business and gave lessons in art. Now she uses the network and life experience that she has built up as a Catawiki auctioneer.

Christine thinks that the story behind an object is what really matters: lovely works of art and jewels become even more beautiful. She places a great deal of importance on tracing the background of her auction items, and regularly approaches the artists herself. It is this care and attention to detail that make her auctions so special.
