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 agatized chalcedony from the Caux county, Normandy! It displays smooth botryoidal concretions ranging from dark brown to coral orange in colour, with good translucency and lustre. A splendid and very hard to come by object!
