Fluorite with Chalcopyrite
stock #13.1-123
Denton Mine, Harris Creek Sub District, Hardin County
Illinois, United States
6.6 x 6.1 x4.8 CM (cabinet)
price: $620


Dark purple-blue Fluorite that is zoned with yellow to orange cores that are best seen with a backlighting. Some faces are dusted with tiny Chalcopyrite crystals and most faces have a lustrous pattern of geometric regrowths. A few edges show modification patterns but most are sharp edged. The Denton Mine is a now one of the great classic localities for USA Fluorite, good specimens are getting very scarce and quite expensive. This is a nice example that is rather dark without backlight but really comes alive with a light behind it.
Quartz - red acicular form
stock #12.1-252
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Far Eastern Region, Russia
6.7 x 5.2 x 2.6 CM (cabinet)
price: $290


The Russian red Quartz from Dalnegorsk is unique in the mineral world. These slender, tapering crystals tend to be darker red at the base and a lighter orange to colorless at the tips. This piece shows the habit and color very well. Minimal matrix and despite some tip cleaves the overall condition is better than most of these delicate sprays.
Grossular
stock #7.AE-315
Seydar, Hoh Nala, Braldu Valley, Skardu district, Baltistan
Gilgit-Baltistan, Pakistan
5.2 x 3.2 x 2.3 CM (cabinet)
price: $620


Dark red-brown clusters of Grossular Garnets that are partly transparent and have minimal matrix. In very good condition, some of the Garnets have contacts or internal cracks that reflect light and in photos look like damage. Crystallized all around from a find at Seydar in the Braldu Valley, this is a not well documented locality.
Acanthite
stock #18-AX-22-175
San Juan de Rayas Mine - Level 407
Guanajuato, Mexico
2.2 x 1.3 x .6 CM (thumbnail)
price: $140


Branching crystals of Acanthite forming a tree-like thumbnail with very bright metallic luster. Complete all around, undamaged and pretty. A very good yet still affordable Silver specie from the famed Guanajuato deposit. This area has been continuously mined for Silver since the discovery in 1585, and this was the world's largest producer for many years. Amazingly there are still a few operating mines and Silver minerals are still found though far less than before.
Danburite and Datolite
stock #14.1-214
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Far Eastern Region, Russia
3.4 x 2.1 x 1.8 CM (miniature)
price: $325


Gemmy light blue Datolite crystals clustered on a gemmy colorless Danburite crystal. The Danburite has some small etched zones that show re-crystallization, but overall this is a sharp prism. From Dalnegorsk, this is a choice miniature of these two species that looks fine from practically any angle. Our background for this specimen does not specify which part of the mining complex was the source for this piece but it seems certain to be from the Bor Pit. No damage; esthetic and unusual.
Citrine and Amethyst with Rutile inclusions
stock #14.1-199
Karur
Tamil Nadu, India
7 x 5.6 x 3.2 CM (cabinet)
price: $370


Sparkling clusters of very clear crystals of Quartz in aligned groups that also have very small needle inclusions of red Rutile. This is from the remarkable deposits of Amethyst at Tamil Nadu (India), that are unique in the world. A few crystals also have sharp hexagonal voids replacing the point of the termination (negative termination). Unusual and attractive, better in person and in fine condition too.
Pericline (Albite), Calcite and Rutile - classic locale
stock #20.1-298
Simplon Railway Tunnel, Termen, Brig
Valais, Switzerland
6.4 x 3.8 x 2.5 CM (cabinet)
price: $330


A classic old Simplon Tunnel specimen from Valais (Swiss ) that is very well-crystallized. This piece dates to the period of 1898-1921, and these old pieces are very rare in any quality. The areas between the white Pericline crystals are lined with Rutile in reticulated masses. The Calcite crystals are sharp transparent scalenohedra which are also fluorescent orange in long-wave. One old label is included. In excellent condition with no visible damage, the Pericline has textbook perfect form.
Dolomite - blue crystals
stock #18.1-031
Muzo Mine, Muzo, Municipio de Muzo
Boyacá, Colombia
5.4 x 4.7 x 4.3 CM (cabinet)
price: $270


A cluster of sharp blue Dolomite crystals from the famed Emerald Mine at Muzo, Colombia. These crystals are over 1.5 cm across and have good luster, form and a color much like a nice Celestite. We obtained this piece in a lot we purchased from the miners in Colombia. They were initially certain they had made a big find of Euclase and were expecting to be very rich. After they learned the sad news that this was "only" Dolomite they were later happy to know that we valued the blue color far more than the normal white and bought everything! Blue Dolomite crystals are in general rare.
