2.9" 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.
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.
