A showy and excellent combination specimen from the recent finds at the famous Commodore Mine at Creede, Colorado of tiny, amethyst quartz crystal nicely interspersed with VERY GEMMY, yellow-green to lustrous, black sphalerite crystals. The two, protruding "horns" of gem and black sphalerite really add character to this piece. The right side and base have to sawed to enhance display. 6.3 x 6.2 x 6.2 cm
A cute thumbnail from Irv Browns TN Collection of a gemmy and lustrous, yellow citrine quartz crystal from Charcas, Mexico. The back is contacted, but is totally out of sight. Seldom do you see TN citrines from Charcas. 2.4 x 1.1 x 1.0 cm
A really cute, pristine miniature of gemmy, lustrous, red spessartine garnets girding a near-transparent, lustrous smoky quartz crystal from recent finds from the Tongbei Area of China. 3.7 x 2.0 x 1.8 cm
A GORGEOUS, curved tiara of glassy, transparent rose quartz crystals of excellent color and crowned by lustrous, green microcrystals of the rare beryllium phosphate zanazziite. This super combination piece probably dates from the 1960s or 70s. See the 1973 Mineralogical Record article in Vol. 4, No. 3. Ex Fred Pough Collection. 3.6 x 1.7 x 1.7 cm
Fine cuboctahedrons of fluorite on matrix to 1.4 cm, with frosty bevels framing glassy faces into the water-clear interiors. The cluster has formed a 360-degree “knob” atop the matrix, making the specimen displayable from either side. 5 x 4.5 x 3.2 cm
I must say upfront that aquas from Mexico are rare to non –existent, making this matrix specimen unusually good. I DID NOT BELIEVE IT WHEN I FIRST SAW IT - BUT IT WAS EVAN'S, AND HE IS really an expert and longtime collector of Mexican goodies. I also verified with others - it is rare, legit, and probably among the very best of its kind. The large aqua measures about an inch atop the quartz, but is technically 4.5 cm in length (extending through the quartz as it does), nestled in a matrix of smoky quartz crystals to 1.5 cm in length. The aqua, is lustrous, translucent, sky blue, with a core of colorless goshenite beryl. The termination, while rough, is comprised of tiny incipient faces and thus terminated quite fully. It is actually doubly-terminated Note the phantom core! . Minor damage or contact does exist, but compared to the significance of the specimen, is unimportant. I was able to get this from Evan directly in a trade. labels from Evan and the Schlepp’s accompany this old timer. 5.1 x 4.0 x 2.8 cm
A crust of botryoidal, translucent, lustrous, opalescent green, “gem silica” / chalcedony has formed over bright green chrysocolla. The spheres reach 1.3 cm across. This exquisite specimen comes with an old, pre-1940 label from preeminent dealer, Lazard Cahn. 5.7 x 4.2 x 2.4 cm
A mass of solid andradite garnet opens into a vug containing many, translucent, lustrous olive green dodecahedrons, .5 cm across, surrounded by frosted, translucent, colorless quartz crystals, to 4.0 cm in length. Formerly in the collections of Martin Zinn and Les Presmyk. Great color contrast! This is one of the finest examples of the material I know of 7.9 x 7.0 x 6.4 cm
This specimen is remarkable for several reasons. The color is a wonderful aquamarine blue, from the cryptocrystalline core to the surface of the specimen. There was a secondary growth of azurite, in crystals to 2.5 cm across, which was later pseudomorphed by sparkling quartz druse. In spite of minor damage to the largest crystal, this piece is rare and exquisite. 7.3 x 7.1 x 3.6 cm
Very closely resembling a rocket, ready for liftoff, this unusual and super matrix, amethyst crystal is doubly-terminated, very lustrous, and exhibits a lovely, rich lilac color. To me the most fascinating characteristic of this amethyst is the fairly uniform hopper growth on all the pyramidal faces. Most unique. From the collection of R.F. Denicourt. This is one of the very largest speicmens I have seen of any single crystal from the locality! 9.6 x 6.0 x 5.0 cm
I preface the word AMETHYST by the adjective to emphasize how DIFFERENT these are from anything you have ever seen from the mine before. these are BETTER...glassier and gemmier...than any other Guerrero find I know of. This is one of the best Guerrero amethysts I have seen in any size. A single, large, intensely bi-colored, transparent, amethyst crystal, to 4.5 cm in length, is girdled by a cluster of smaller amethyst crystals. From Colorado dealer, Dennis Beals, who handled this small pocket several years ago. This is absolutely one magnificent specimen! 5.2 x 3.2 x 2.7 cm
8.1 x 3.1 x 2.4 cm. This is a superb amethyst, different from anything ever seen from the mine before. These are glassier and gemmier than any other Guerrero find I know of. This amethyst specimen is very similar to the specimen preceding it. The large, intensely bi-colored, transparent crystal, is 7 cm in length. It too is surrounded by smaller amethyst crystals. There is extremely minor chattering at the termination of the large crystal, but it is insignificant in context. From Colorado dealer, Dennis Beals, who handled this small pocket several years ago.
A large and STUNNING crystal, 14.5 cm in length, is front and center on this wonderful Swiss piece. It has that amazing gemminess characteristic of fine Swiss smokies, and the perfect degree of smoky color – not too dark, not too light. The main crystal sits on top of another gemmy crystal (this crystal underneath is chipped at the lower termination but it acts merely as a “setting” for the main crystal anyway; it IS terminated at the upper end). Both crystals are attractively arranged on a carefully-trimmed matrix. 18 x 9 x 9 CM cm
4.5 x 3.9 x 3.0 cm. Intergrown, glassy, translucent, color-zoned, olive-green apatite crystals nicely accented with quartz form a fine specimen from the Panasqueira Mines of Portugal. The tabular crystals have textbook, hexagonal form. No damage to the major crystals. Highly representative material from this classic locale from its heyday in the 1960s-1980s. These large crystals are exceptionally well presented, and lustrous. Ex. Wes Parker Collection.
Showy plate of smoky quartz, from a recent find at a gold mine in Bolivia. The crystals are unlike any other smokies I have seen. They have a gorgeous silky luster, and internally, the blushes of color (and even chevron phantoms) characteristic of Brandberg and Guerrero quartz. In great condition, with damage to only a couple of crystals on this whole magnificent plate! 19 x 14 x 7 cm All Content and Design ©1996-2012 The ArkenstonePowered by http://mineralwebsites.comMineral Specimens by species; or by specimen id. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
