Lovely light pink to dark magenta Cobalto Calcite (AKA Cobalticalcite, Sphaerocobaltite, and Cobaltian Calcite) from the Kakanda Mine, Shaba Province, Zaire, Africa.

This is a variety of Calcite containing Cobalt. The result of the cobalt is that the calcite is colored a pale pink. In pure sphaerocobaltite (most examples contain a small but significant percentage of calcium), the coloring effect is magnified.

This material is often called Pink Drusy. Drusy (or druse) is a trade name for a natural surface coating of fine crystals that sparkle. Sometimes the crystals are quartz and those crystals will usually reflect the color of the mineral below. Sometimes the crystals may actually be of the same minerals that occured in the rock below.
