Killer gem crystals of thaumasite from the famous NChwaning II Mine, Kalahari manganese fields, South Africa. Thaumasite is a very rare mineral with an unusual chemical composition. The hexagonal prismatic crystals are very well terminated and sharp. They are transparent and gem with a light yellow hue. They have a strong luster and light reflection. In superb condition. On acrylic base.

Fine and rare thaumasite!
