1.1" Fluorescent Scheelite and Dolomite Association - Yaogangxian Mine

This is a gorgeous association of scheelite and dolomite that was collected from the Yaogangxian Mine in China. Under shortwave UV, the scheelite fluoresces a vibrant white-purple color. This specimen comes on a piece of mineral tack within an acrylic perky display case.

Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate (CaMg(CO3)2).

The mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. It does not rapidly dissolve in dilute hydrochloric acid as calcite does. Crystal twinning is common.

Dolomite was first described by Carl Linnaeus in 1768, and in 1791 it was described as a rock by the French naturalist and geologist Déodat Gratet de Dolomieu. He first recognized the material in buildings of the old city of Rome, and later as samples collected in the mountains known as the Dolomite Alps of northern Italy.
