Zircon on Aegerine Zircon on Aegerine Zircon on Aegerine Zircon on Aegerine

Fine large Aegerine crystal with associated Zircon and Orthoclase. Note that this is not from Mt. Malosa, but from nearby Mulanje Mountain which is producing a similar suite of minerals as Mt. Malosa. This one has everything going for it, firstly it is a stout crystal at 3.1 cm wide, much more impressive than the typical pencil crystals. It also has great luster and a fine tapering termination, and a bonus of yellow Zircons on two sides. No damage.

Magnesio-axinite Magnesio-axinite Magnesio-axinite

Fine single crystal with a wonderful lavender color. These are very hard to find in this quality as most are mere shards or partial crystals, especially in this size range. This one is complete a free of damage except for a couple very trivial nicks along the edge. One side has a more smooth and uniform sharp edge with the other a more serrated edge.

Bright, vivid green crystals of Brochantite on and embedded in Anglesite. Brochantite and Anglesite occurred together from the second oxidation zone of the mine and is considered a rarity for Tsumeb. At the time it was considered the world's best, now second to the Milpillas Mine. A beautiful piece that would be a great addition to a Tsumeb suite.

Senegalite with Turquoise Senegalite with Turquoise

Large, vuggy specimen of the rare phosphate Senegalite from the type locality for the species. Open vugs reach 6cm wide and are fully lined with Senegalite. This is the most aesthetic Senegalite I have ever seen with large sized vugs and good color highlighted against the blue Turquoise underneath. Good vugs on both sides of specimen with very little matrix, you get really not much more than the crystal lined vugs. From the Alain Carion collection.
