Description
Remarkable cobalt calcite found in Congo, formerly Zaire. These tumbled stones possess a completely natural, deep rose-red to pink color. They are very attractive and unique. Cobalt calcite is found as small crystals at many cobalt ore sites worldwide, but it is the mines of Shaba, Zaire, that have produced the most remarkable specimens. Besides the properties of calcite, these crystals are called crystals of joy.
