Sturmanite with Gaudefroyite
Sturmanite is a very rare, and pretty, calcium iron sulphate borate hydroxide hydrate which was discovered in the manganese mines in Northern Cape, South Africa in the early 1980s, and which has not been found anywhere else in the world to any consequence. This very small miniature specimen is a lovely aggregate of brightly coloured yellow prismatic Sturmanite crystals up to 1.4 cm in length, and in great shape. Associated with this grouping are a few small black Gaudefroyite crystals. Ex David Hardman Collection.
