Expert Diamonds

A diamond is the most perfect mineral on earth.

Maria René  Piacenza Bernal

Maria René Piacenza grew up with minerals. That's what happens when your father is a geologist. The passion was passed onto her and a study of gemmology followed. Immediately after her studies, she started working as an analyst, providing certificates for diamonds. That's how she learned to work in a very detailed way, a quality that often comes in handy in this profession. After a few years, Maria René Piacenza wanted to develop her capabilities further. She did this in London, where she worked in diamond sales and continued her gemmology studies. She then studied in Antwerp, after which she returned to Italy and started as a gemologist and diamond trader.

After more than twenty years of being surrounded by diamonds, Maria René Piacenza now uses her enormous knowledge and experience for Catawiki. Her experience in certifying is invaluable. Maria René Piacenza likes to work with her fellow experts. With their combined knowledge, they know the market like no other and maintain good contact with sellers. With her sales experience, Maria curates her auctions as a shop window, with the finest diamonds. This way she delivers an auction every time that is irresistible to the real enthusiast.
