Fumery collection, acquired in early 2025, was, in our opinion, a spectacular set of more than twenty chalcedony geodes from the Pays de Caux on the Normandy coast. Passionately assembled over more than 40 years of research and acquisitions by C. Presa and O. Fumery, this collection is undoubtedly the most complete set of chalcedony from this iconic region assembled in recent decades! Here is a remarkable geode of quartz-chalcedony from the Caux county, Normandy! The quartz crystals are very sparkling and it makes for an eye-catching geode!
