3.6" Libethenite on Lustrous Cobaltoan Dolomite - D.R. Congo
This is a lustrous cobaltoan (cobalt-bearing) dolomite crystal cluster with tiny libethenite crystals scattered throughout, collected from the Kakanda deposit in the Democratic Republic of the Congo.
Comes with an acrylic display stand.

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.

Libethenite is a secondary copper phosphate mineral with the chemical formula Cu2PO4OH. The crystals are typically dark green and orthorhombic in shape and form within the oxidation zones of copper ore deposits.
