3.3" Blue-Green Aragonite Aggregation - Wenshan Mine, China

This is a beautiful, blue-green, botryoidal aggregate of aragonite. The individual crystals that make up this specimen exhibit a wonderful sparkle and bear a velvety luster when rotated under a light source. This specimen was collected from the Wenshan zinc mines in the Yunnan Province of China.

It comes with an acrylic display stand.

Aragonite is one of two common calcium carbonate (CaCO3) minerals: the other is calcite, of which aragonite forms as a pseudomorph. Its crystal lattice differs from calcite, resulting in a different crystal shape. It displays a translucent to white color when pure, and when impure can vary between yellow, green, pink, blue and brown. It typically forms in low-temperature hydrothermal veins, in hot springs, and as precipitates from chemicals in sedimentary rock. It can also form under biological processes: aragonite forms naturally in most mollusk shells, and as the calcareous endoskeleton most corals.
