Mineral Specimen #4994    Calcite with Unidentified Pink Alteration, Chalcopyrite

Sweetwater Mine, Viburnum Trend Dist., Reynolds Co., Missouri

4.2 x 1.9 x 1.5 cm
1.7 x 0.7 x 0.6 in


On this hexagonal Calcite specimen, the Calcite has altered to an unidentified pink colored material just above the boundary of the Chalcopyrite. This may not actually be an alteration but a case where the Calcite is colored with an impurity. In either case, I have never seen a similar specimen from the location. However, there have been similar hexagonal Calcite crystals with a layer of green material at the base which is usually attributed to being Malachite. The rest of the Calcite specimen is translucent and has a good glossy luster.

Condition: Very Good

Flaws: There are a few very small chips on the edges of the termination.
