Olmiite and Quartz from N’Chwaning Mine, South Africa

288.48$

A stunning specimen of olmiite and quartz from N’Chwaning Mine, South Africa. Olmiite is a rare calcium-manganese silicate that was named after an Italian mineralogist called Filippo Olmi. Olmiite is a product of hydrothermal alteration. As such, it grows in manganese-rich hydrothermal replacement deposits. The crystals form by going through metamorphosis due to the hot hydrothermal fluids passing through a manganese deposit, adding silicon and calcium to the pre-existing elements. To this day, the only known locality of this mineral is in the Kalahari Manganese Field of South Africa. Video of the specimen here.
