Smithsonite, Calcite and Rosasite from the Barbara Mine, Laurion, Greece – cabinet specimen as unique piece
This cabinet specimen features an impressive mineral association of Smithsonite, Calcite, and Rosasite from the well known Barbara Mine in the Laurion district of Greece. Large parts of the iron rich matrix are covered by light to silvery white Calcite coatings on which numerous rounded to botryoidal Smithsonite crystals in delicate greenish color have developed. Between them are intense turquoise to bluish green Rosasite coatings and fine crystalline aggregates, creating an exceptionally colorful contrast. The crystals are clearly visible and together with the open structure of the matrix give the specimen a highly aesthetic appearance.
Geology & origin
The Laurion district in Greece is one of the classic mineral localities of Europe and has been famous since antiquity for its polymetallic ore deposits. Especially the oxidation zones of the old lead and zinc veins produced an enormous variety of secondary copper and zinc minerals. Smithsonite forms there as a secondary zinc carbonate commonly occurring in botryoidal crystal aggregates, while Rosasite as a copper bearing carbonate creates characteristic bluish green coatings. The Barbara Mine is one of the best known localities of the district and produced numerous high quality collector specimens with colorful mineral associations.
