What is Olmiite?
Olmiite is a relatively new mineral that is approved by IMA in 2006. Before that, the specimens from the Kalahari Manganese Field, South Africa are confused with its calcium dominant analogue poldervaartite. It shows a pale to moderate pink color, sometimes slightly brownish. Specimens showing ball-shaped or bowtie-shaped crystal clusters are highly welcomed by the collectors.
