17.8 x 9.0 x 5.0 cm. The only specimen I have seen like this, in such quality. This piece has a 9 cm doubly-terminated quartz atop a larger, extended quartz shard; and the whole quartz shard is included here and there by beautiful lepidolite, giving a golden "glow" when backlit o the whole specimen.
A sharp smoky point with CRYSTALLIZED goethite (not the ugly amorphous type) in spray-like blades. Fine Colorado combo mini. 4.7 x 3.7 x 3.3 cm
These bizarre quartzes, from a single find in China a few years back, have all but disappeared from the market - and this is one of the finest I have seen. The milky crystals look like rockets or comets, connected with tiny stalks to a thin "base". The natural process that forms these remains a mystery -- but they are certainly unique and wonderful quartz specimens. 6.0 x 3.6 x 2.4 cm

A DRAMATIC and SHOWY milky quartz crystal with two sprays of lustrous, brown eosphorite blades elegantly attached to a termination face of the quartz crystal. Tiny, smaller esophorite crystals totally coat several of the quartz crystal faces and ROSE QUARTZ randomly encrusts the milky quartz crystal. This one-time early 1970s Brazilian find is discussed in Bancrofts Gem & Crystal Treasures book. The pegmatite deposit is on an island in the middle of a major Minas Gerais river and can only be worked for about 4 months a year. Annual flooding prevents mining the rest of the year! None like this have been found in over 20 years. A very desirable specimen. 7.0 x 5.8 x 4.6 cm
A very lustrous, very pretty quartz tinted green by hedenbergite inclusions from this famous Greek locality. Very good color! 7.7 x 7.2 x 5.2 cm
18.4 x 9.7 x 6.4 cm. This specimen is a rare matrix alpine quartz plate, hosting totally gem crystals to just over 5 cm, on a matrix of adularia-dotted granite. Good matrix pieces are hard to come by, and strahlers risk their lives to collect such as these. To bring out a piece like this, undamaged, the collector must recover it in a larger plate and then haul down the mountain a considerably larger specimen to trim later at home. It is not a collecting trip for the faint of heart. This was found by a very well-known strahler, Paul von Kanel, and was in his personal collection. The crystals, but for a few on the periphery, are totally pristine and all are clean and gemmy.
7.2 x 5.5 x 4 cm. A stunning set of three doubly-terminated Hematite-included Quartz crystals, sitting on a larger white Quartz crystal. The largest of the included Quartz crystals is 5.5 cm long. All have excellent luster. Incredibly aesthetic. Ex. Charlie Key.
14 x 6.5 x 3.2 cm. We have never seen anything quite like this shimmering piece that looks like sugary blue syrup was poured over a plate of quartz crystals. This is an eye-catching large (14 cm) specimen of gorgeous sky-blue plancheite coating Quartz crystals (many of which are doubly-terminated) in what seems half of a natural pocket or cavity containing them. The largest of these coated Quartz crystals is a 1.8 cm. Then, drusy quartz was deposited lightly atop to give the piece a fabulous sugary sparkle, which cannot be adequately captured in the photos. They only give a hint. Ex, Charlie Key.
Two Colorado classics together: euhedral crystals of very slightly salmon-colored microcline, with sharp smoky quartz points. 4.7 x 4.2 x 3.0 cm
8.5 x 7 x 4.8 cm. An exceptional Amethyst scepter (cap) with good color and luster from the increasingly important Orange River area of South Africa. The Amethyst scepter itself is an incredible 6 x 4 x 4 cm. Amethyst, truly, is rare from Orange River localities as opposed to the more northerly Brandberg and Goboboseb locales. Ex. Charlie Key.
8.8 x 7.3 x 3.8 cm. A very complex and appealing combination piece of beautiful blue Shattuckite (in both pocket velvety coatings and in more robust complete sphere forms) complemented nicely by vivid green drusy Malachite. The velvety Shattuckite pocket is 3 x 2 cm, while the spheres range up to 1.6 cm across on other parts of the specimen. Very aesthetic, and these complete spheres are quite rare, so it’s a good combination of beauty and interest. Ex. Charlie Key.
5 x 4.8 x 2 cm. A very nice single complex Fluorite crystal sitting on a plate of Quartz crystals. The gemmy, yellow-amber Fluorite is 1.9 cm across, and is an octahedron modified by stepped cubes, giving it the appearance of a Mayan pyramid. A very good Erongo piece of highly unusual habit. Ex. Charlie Key.
5.7 x 4.8 x 3 cm. A very nice plate of highly-modified Fluorite crystals with silky luster but gemmy interiors, intergrown with a few nice Quartz crystals. The Fluorites have the classic Erongo purple zoning along some of the edges and corners, and they average about 1.5 cm across. A very good, appealingly unusual specimen for this famous locality. Ex. Charlie Key.
6.8 x 2.2 x 1.8 cm. A beautiful single crystal of light Smoky Quartz, terminating in a sharp Amethyst reverse scepter. The crystal is gemmy throughout. The Smoky portion has striated, slightly frosted faces while the scepter has superb luster. There are also many fine Tourmaline needle inclusions in the Amethyst tip. A very aesthetic, and not very common, specimen. Ex. Charlie Key.
4.3 x 4 x 3.8 cm. A splendid miniature of lustrous, beautiful Hematite-included Quartz scepters. The color, form, and architecture of this specimen are highly aesthetic. The main crystal is 3.3 cm long, and has a 1.6 cm scepter (cap). An excellent specimen overall. Ex. Charlie Key.
