Quartz scepter with Hematite from Orange River, Karas Region, Namibia [db_pics/pics/j895d.jpg]

Quartz scepter from a 2017 find, and one of the best I saw. The scepter head has both smokey and amethyst coloration and the stalk is pink due to Hematite inclusions. Complete all around. Withthe exception of two tiny crystals sticking into the side, the specimen is entirely undamaged. The combination of the colors and form make for a great specimen.

Laterally compressed translucent white Calcite crystal completely covered by a layer of sugary Quartz crystals, with attached double-terminated pink Stilbite crystals to 3.5cm. Unusual specimen that is reminiscent of Steve Smale's specimen known as 'The Cricket Bat' (see page 117 of the Smale Collection book). One tiny Stilbite crystal is incomplete, otherwise undamaged, with the Stilbite only on one side. Only the second one like it I've seen.

A very good example of the very rare Antimony Oxide, Valentinite. This specimen features both single crystals to 7mm (good sized!) and hemispherical crystal groups. More good crystals on the back side too.

Feldspar var. Moonstone from Namalulu, Tanzania [db_pics/pics/J810e.jpg]

Blocky, grey/white Felspar crystals from a recent (and seemingly one time) find of crystallized moonstone from Tanzania. This is the single best specimen I've seen with both quality, well formed crystals and good color. The main crystal is 4.1cm wide and displays a satiny blue color across the end surfaces. This 'Schiller effect' is seen when you turn the crystal under lighting. Good color can be seen on a number of the other smaller crystals too. Moonstone crystals are rare!

Massive Ajo Copper with a row of tall crystals to 13cm. This formed in a thin seam and has a uniform thickness throughout the specimen. This was in an old collection I bought and based on the other minerals in the collection, I estimate it's from the 1970s or 1980s.
