3.8" Polished Cobaltoan Calcite Slab - Congo
This is a hand-polished slab of pink cobaltoan calcite from the Congo. The lapidary work is nice, and allows for the vivid coloration of the cobaltocalcite to be easily seen. There is also a metallic luster that shines in the light when the specimen is rotated, some of this is attributed to native copper inclusions. A few spots of chrysocolla (copper oxidation) can be observed throughout the face of this specimen. Comes with an acrylic display stand.
