A gorgeous pastel pink Cobaltoan Calcite specimen. One side of the host rock is completely covered with pink crystals, with the rest of the rock also slightly pink from the cobalt content. An unusual cluster, there aren’t too many pinks in nature and this is a nice large affordable piece. Great for jewellery making or just to admire as is.

Cobaltoan Calcite (Ca,Co)CO3
A variety of calcite containing Co2+ replacing Ca.
Calcite, which gets its name from “chalix” the Greek word for lime, is a most amazing and yet, most common mineral. It is one of the most common minerals on the face of the Earth, comprising about 4% by weight of the Earth’s crust and is formed in many different geological environments. Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. The amazing variety of colour and varying crystal shapes makes Calcite a very popular mineral among collectors and crystal lovers alike.
