Olmiite is a fairly uncommon mineral, only being found in the Kalahari Manganese fields. It is also relatively new, having only been named by the International Mineralogical Association (IMA) in 2006. For many years it was considered to be poldervaartite, but recent analysis has shown showed olmiite to be a distinct species, making the specimen offered here particularly enticing.
