This is a superb miniature, competition quality! Extremely lustrous, these opaque white crystals represent the plumbian or lead rich variety of aragonite. They are perched nicely on matrix and the main crystal measures 3.5 cm in length. This variety of aragonite reaches its zenith only at Tsumeb. Moreover, the tarno is in association with calcite, and good rhombohedral crystals at that, a novel association to me. 3.5 x 3.4 x 3.1 cm
