Calcite

A trio of intergrown bi-colored crystals in awesome condition. These were typically acid dipped and it is so nice to see one with its original soft luster. The internal cleaves reveal a series of color zones ranging from a pale purple to soft amber. As the specimen is turned these zones appear to alter the internal light in such a way as to confuse the observer as to which areas are which color. If you don’t have one this may be the specimen for you!

Locality: Tri-State area, Joplin,  Missouri

Composition: calcium carbonate
