9 x 7.5 x 6 cm. Botryoidal fluorites are rare. They are best known from this Indian locality, and from a recent find in China (purple ones). This one is unusually translucent for one of these – in fact, you can faintly see all the way through it. Second, it is complete all around, with no contacts, and perfectly round. And finally, it is nestled in a perfect “nest” of light purple amethyst crystals as opposed to the normal white quartz.
7.5 x 6 x 6 cm. The vast majority of Brandberg quartz specimens are single crystals. Of those that are matrix specimens, a very small number are associated with prehnite. The attractive isolation of the lone, gemmy quartz crystal with its elegant blush of smoky color at the termination is striking. Note the small bloom of some kind of pseudomorph (we think) crystals on the side of the quartz crystal.
5.5 x 5.5 x 3.8 cm. Lustrous, translucent and frosted, emerald-green fluorite crystals with purple zoning are richly and attractively attached to the side of three, intergrown, highly lustrous, tapered, parallel-growth schorl crystals with a myriad of terminations from recent finds at Erongo Mountain, Namibia. This fine, complete-all-around, nearly pristine piece even has a couple of glassy, smoky quartz crystals embedded at the base on the other side. Excellent combination material from this famous locale.
3.4 x 2.8 x 2.0 cm. A superb specimen featuring sharp crystals of metazeunerite to 7mm perched on a complete smoky quartz crystals. They come from a small pocket found in 2003 in granite, East of Tubussis (see NAMIBIA book, page 650). This specimen is in fact illustrated in the magnum opus NAMIBIA book which cam out last year in Germany (page 650, bottom). Ex. Heini Soltau Collection.
9.7 x 4.8 x 4.4 cm. Sharp crystals with the brilliant lustre and internal sparkle that seem to characterize this find. The largest crystal is 1.7 cm. One doubly-terminated crystal is just over 1 cm. Beautiful amethyst from an unusual locality, found May 2008. They are all from what the collectors (Luca and Fabrizio Ferrero) called "the labour day pocket".
8.6 x 7.0 x 6.9 cm. Particularly intense purple crystals with the brilliant lustre and internal sparkle that seem to characterize this find. The largest crystal is 1.2 cm but the intense color set against the sparkling greenish (prehnite?) vug behind the gate of the crystals, makes it a special piece. Beautiful amethyst from an unusual locality, found May 2008. They are all from what the collectors (Luca and Fabrizio Ferrero) called "the labour day pocket".
10.2 x 6.4 x 5.6 cm. Sharp crystals with the brilliant lustre and internal sparkle that seem to characterize this find. The largest crystal is 2.2 cm. This is among the larger of the find. Beautiful amethyst from an unusual locality, found May 2008. They are all from what the collectors (Luca and Fabrizio Ferrero) called "the labour day pocket".
6.5 x 4.6 x 3.8 cm. Sharp crystals with the brilliant lustre and internal sparkle that seem to characterize this find. The largest crystal is 1.25 cm. Beautiful amethyst from an unusual locality, found May 2008. They are all from what the collectors (Luca and Fabrizio Ferrero) called "the labour day pocket".
9.0 x 8.6 x 5.6 cm. Sharp crystals with the brilliant lustre and internal sparkle that seem to characterize this find. The largest crystal is 1 cm but there are many, protectively arranged at the entrance to this pocket. Beautiful amethyst from an unusual locality, found May 2008. They are all from what the collectors (Luca and Fabrizio Ferrero) called "the labour day pocket".
6.2 x 5.0 x 4.2 cm. Sharp crystals with the brilliant lustre and internal sparkle that seem to characterize this find. The largest crystal is 1.7 cm and doubly-terminated. This is among the larger of the find, and there is much color on this small matrix specimen...the crystals are the deeper hue to come from the find, it seems. Beautiful amethyst from an unusual locality, found May 2008. They are all from what the collectors (Luca and Fabrizio Ferrero) called "the labour day pocket".
6 x 4.2 x 3.7 cm. A fine 5.7 cm Silbite bowtie sitting perfectly across a Quartz stalactite. The luster is superb, and the salmon color is striking. There are several smaller Stilbites growing from the knot of the bowtie. Ex. Charlie Key.
Okay, so it's a Herkimer quartz, but - how often do you see a thumbnail this good - of ANYTHING? Three diamond-like crystals perfectly arranged on just the merest bit of matrix - you just have to love it, "Herkimer diamond" or not. 2.5 x 2.3 x 1.2 cm
3.8 x 3.7 x 2.8 cm. An excellent clear gemmy Topaz sitting across a Smoky Quartz crystal from the Spitzkopje locality. The Topaz is 3.7 cm long, and the over all mass is 30 g. The Topaz’s luster is excellent, and there is even a partial termination along the bottom. Ex. Charlie Key.
4 x 3.2 x 2.5 cm. These garnets have a beautiful uniform deep orange color, fine gemminess, and excellent luster, reminiscent of Jeffrey Mine specimens. Most of the Spessartines are 2-3 mm, but some actually reach .5 cm, and with their gemminess, they absolutely glow under light. The small (.5 cm) Smoky Quartz crystals are well-terminated, while the largest are contacted on some sides. Ex. Charlie Key.
3.2 x 3.1 x 1 cm. A rare and attractive specimen of Sulphur-included Quartz. The luster on the Quartz is silky, and the overall impression of the piece is very good. An unusual piece for both the locality and the combination. The quartz is broken on all sides, though. Ex. Charlie Key.
