Large Quartz pseudomorph after Feldspar. These are known as 'Gitter Quartz\" (a German name for fence or lattice Quartz) or simply 'Lattice Quartz'. The Quartz crystals normally form epitaxially on Feldspar with either single or multiple Feldspar crystals covered with oriented Quartz crystals on the sides. This one however is a complete replacement of the Feldspar (you see nothing but Quartz when looking at the base). It's both large in size and has large Quartz crystals that extend out in four directions from the former Feldspar crystal. The base is recrystallized. The Erongo Mountains is the only locality I'm aware of that produces this style of unusual Quartz specimens.

Two cherry red Rhodonite crystals with Galena from Broken Hill. This is an old piece recently released from a collection and stands out for the translucency and color of the crystals. The right crystal is well terminated while the left crystal is a partial crystal. Both crystals show areas of gem transparency which is not common for these.

Large single Quartz crystal with bright blue inclusions of an unknown type. This was in the Luis Menezez collection and found decades ago. It shows some edge chips, however it was the largest, best quality crystal of the only handful of crystals available in the collection. Big, colorful, and unusual.

Jackstraw cluster of Cerussite crystals with green Copper staining. Ex. Dennis Ewell collection.

Glassy, transparent purple Adamite crystals on Limonite. The crystals are very bright and lustrous, but hard to get good photographs of, much better in person. Ex. Dennis Ewell collection.
