#22 / CALCITE - India
Locality: Mumbai, Maharashtra, India
Size: 6 x 5 x 5 cm
The satin luster on this Indian Calcite is the result of thousands of tiny faces on the main faces of the crystals. The large crystal and its accompanying side car crystal are on some pale green prehnite on basalt matrix. All the cleavage plane lines that you see are entirely interior and do not comprimise the exterior surface of the crystals.
Good Calcites from the Indian basalts are uncommon and difficult to obtain.
