A large, showy, sharp, translucent and lustrous smoky quartz crystal from the famous Two Point Mine, Teller Co., Colorado. Trivial edge damage on a termination face and a very small chip on one face certainly do not detract from the beauty of this piece. Unusually large and fine smoky for the find! 9.6 x 2.6 x 2.0 cm
A GORGEOUS and PRISTINE plate covered with at least 10 transparent to translucent and lustrous Japan-law twinned quartz crystals to 2.7 cm across from the Ullpac Mine in Peru. 7.5 x 5.7 x 2.9 cm
3.5 x 2.9 x 1.8 cm. The hardest crystals become the softest?! A superb specimen of two, super-sharp, complete-all-around, pseudohexagonal, light brown talc pseudomorphs after quartz crystals. This fine old-time piece is from a renowned locality for this rare replacement - the Johannes Mine, Bavaria, Germany. The quartz pseudomorphs are so sharp, that they look man-made, but the beautiful patina is diagnostic, that it is, in fact, natural and not carved from a massive talc block. It once was called "steattite". Ex. Mullane Collection.
5.2 x 4.4 x 3.8 cm. A fine cluster of sharp, transparent smoky quartz crystals with excellent color from Graubunden, Switzerland. The smoky quartz crystals project in different directions, giving a striking appearance. One of the large crystals has this incredible, interior, rainbow prism effect, which is plainly visible in the photos. The terminations of the two largest smoky quartzes are in very good shape: one is pristine; and the other has only very trivial edge-wear. Ex. Tribbey and Tarnowski Collections.
3.8 x 1.8 x 1.2 cm. Three translucent, purplish-blue, stepped-growth face fluorite octahedrons are nicely set on a plate off glassy quartz crystals on this fine miniature from one of the famous mines at Dal’negorsk, Russia. The fluorites are moderately lustrous. This is an unusual, older fluorite varietal from this renowned locale. Ex. Dr. Eric Asselborn Collection, who obtained this piece in the early 1990s, when Dal’negorsk material first started coming to the market. Rare habit for locale.
11.0 x 7.4 x 7.4 cm. Very glassy, lustrous, doubly-terminated, di-pyramidal, "beta-style" smoky quartz crystals are very richly and aesthetically scattered on both sides of the mounded cabinet matrix covered with sparkly, bladed, black hematite rosettes on this classic and showy specimen from the Florence Mine of Egremont, England. The quartz crystals reach 1.9 cm. They look like beta quartz (a special heat-induced and unusual crystallographic form of quartz) superficially but really are not, despite most of us thinking so. There is even a scattering of scintillating, specular hematite microcrystals. The matrix is massive hematite.
6.9 x 3.8 x 2.8 cm. This is a fine and probably old specimen of amethyst form the ancient workings of quartz in Idar-Oberstein, used for centuries for carving and lapidary art. Still today, the world center of the highest end of the lapidary crafts is based in Idar-Oberstein, though stone to work on is now imported from elsewhere. This is a rich and beautiful pocket of amethyst. Very rare today to get any specimens of this material. It has amethyst crystals with two shades of purple: a bright, luscious, grape purple; and a much darker purple. Ex. Stevens Institute of Technology (Hoboken, New Jersey) and Richard Hauck Quartz Collection.
6.3 x 5.8 x 3.8 cm. A striking, fine, floater quartz crystal cluster from a classic, old locality. The glassy, transparent, doubly terminated crystals are essentially pristine and have fascinating, layered, clay inclusions. One side of this amazing cluster has the "alligator" quartz look. This piece bears a strong resemblance to the Herkimer quartz "diamonds" of New York, but this old lead mine closed in 1932.
A very aesthetic, amazingly shaped and pristine smoky and amethyst quartz scepter with a row of amethyst-tipped quartz crystals growing off of the side of the scepter stalk. The three intergrown amethyst and smoky quartz crystal sceptor heads are all doubly-terminated! This is a beautiful and unique miniature from Brandberg, Namibia. 4.5 x 3.4 x 1.3 cm
25.5 x 14.5 x 6.8 cm. This Chinese fluorite find has to be one of the most exciting of the past five years - large plates of razor-sharp octahedrons with unique purple and green tones, in contrasting stark white quartz. The mining has stopped now - any specimens you see are from existing stock. The crystals on this dramatic large cabinet plate measure to 3.0 cm.
10.0 x 7.5 x 4.3 cm. A striking, cabinet specimen from Colorado of two, interestingly angled, differently shaped smoky quartz crystal coated with sparkly goethite needles. The spiky smoky quartz also has rare onegite crystals, which is an early name for hair-like inclusions of goethite in amethyst. This is an excellent, complete-all-around specimen. Collected in 2000 from the Dragon/Torch Pocket at the Dreamtime Mine. Ex. Adam Sotomayor, who collected it.
9.7 x 8 x 6 cm. A dramatic large piece featuring an excellent doubly-terminated 5.5-cm Aquamarine with very good color, superb luster, and gemmy terminations. The associated Orthoclase, Smoky Quartz, and Schorl also have well-developed crystals. Some of the Orthoclase has been weathered, making for a stark contrast to the sharper geometry of the aquamarine itself. Ex. Charlie Key Collection.
7 x 4.5 x 4 cm. A beautiful cluster of five Amethyst crystals on Quartz from the Brandberg locality. The Amethysts have deep purple zoning and luster that ranges from good to excellent. The largest of the Amethysts is 2.3 cm, and they are arranged just about perfectly on the Quartz-crystal matrix. Ex. Charlie Key.
3 x 2.3 x 2.1 cm. An attractive, classic cluster of red Rhodocrosite scalenohedrons from one of the world's great Rhodochrosite mines. The largest of the crystals is 1.7 cm long, the luster is excellent, and the gemminess is better than you normally find. On most N’Chwaning Rhodochrosites, there is cleavage on the tips of some of the scalenohedra, and this specimen is no exception. There is also an attractive partial drusy coating (Quartz) on some of the Rhodochrosites, adding a very pleasant contrast. They have not been mined since the early 1980s. Ex. Charlie Key.
4.5 x 3.2 x 2.7 cm. A geometric cluster of five gorgeous Schorl crystals. Each of the crystals, the largest of which is 2.2 cm, have outstanding luster and beautiful striations. The complex blocky habit is very consistent among the crystals, and it is virtually pristine. Ex. Charlie Key.
