Smithsonite, Calcite and Rosasite from the Barbara Mine, Laurion, Greece – cabinet specimen as unique piece
This cabinet specimen features an attractive combination of Smithsonite, Calcite, and Rosasite from the Barbara Mine in the famous Laurion district of Greece. Numerous light gray to white Calcite crystals are positioned on the reddish brown iron rich matrix, accompanied by spherical to botryoidal Rosasite aggregates in their typical greenish color. The different mineral formations create a strong contrast in both color and texture. Especially the fine Rosasite crystals give the specimen a vivid and aesthetic appearance. The open structure of the matrix with its cavities and crystal surfaces makes this specimen particularly varied and collectible.
Geology & origin
Laurion in Greece is one of the most important historic ore districts in Europe and is world famous for its extraordinary variety of secondary lead, zinc, and copper minerals. The Barbara Mine produced numerous high quality collector specimens with colorful oxidation minerals. Smithsonite forms there as a secondary zinc carbonate, while Rosasite is a copper zinc carbonate commonly occurring in botryoidal aggregates. The association with Calcite on iron rich matrix is typical for the complex oxidation zones of the Laurion deposits and is highly appreciated among collectors of classic Greek minerals.
