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