Fluorite on Sphalerite
Elmwood Mine, Carthage
5.3 x 4.3 x 3 CM (cabinet)
A sharp single Fluorite perched on a complexly crystallized Sphalerite matrix. The Fluorite is transparent, and has geometrically etched, stepped structures on its faces. The front or display side is in perfect condition, a tiny cleave is noted on the back side that is almost invisible by naked eye. The Fluorite is like a small jewel, the color is purple blue. There are still some good values to be found in Elmwood Fluorites.
Fluorite with Chalcopyrite
Denton Mine, Harris Creek Sub District, Hardin County
6.6 x 6.1 x4.8 CM (cabinet)
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
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Far Eastern Region,
6.7 x 5.2 x 2.6 CM (cabinet)
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.
Seydar, Hoh Nala, Braldu Valley, Skardu district, Baltistan
5.2 x 3.2 x 2.3 CM (cabinet)
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.
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.
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
Muzo Mine, Muzo, Municipio de Muzo
5.4 x 4.7 x 4.3 CM (cabinet)
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.
Cerussite crystals in several habits with an unknown inclusion that gives a yellow-orange color. The matrix is typically complex and very three-dimensional. Tsumeb Cerussites were found in every imaginable form and sometimes colored by inclusions. This color is very unusual, and we have not seen this before. Under strong magnification the inclusions appear to be fibrous and aligned along the crystal axis. With Tsumeb minerals mysteries are a big part of the fun. The condition of this piece is also remarkable, there is no damage even though the Cerussites are well-exposed and prominent.
