Goethite is a well-known common secondary mineral at Tsumeb, but rarely forms attractive specimens. This example certainly bucks the rule! Superb, slightly distorted spheres, to 1.4 cm diameter, of semi-lustrous black Goethite form a grape-like cluster on a mixed matrix of rusty Limonite and 1 mm rhombohedral Calcite crystals. Some of the Goethite spheres are broken to reveal a shell of radiating Goethite micro-crystals with a hollow interior lined with transparent glassy Calcite crystals. A well-priced and excellent small miniature of Goethite from Tsumeb.
