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.

SOLD Magnetite - Vintage Swiss
stock #SOLD 18.1-642
Zermatt, Matt Valey, Zermatt-Sass Fee area
Wallis, Switzerland
2.5 x 2.1 x 1.5 CM (thumbnail)
price: $0


A neat old Swiss thumbnail of well-formed Magnetite octahedrons. Ex A. Kranz, his original label can be dated being written between 1850 to 1888. In good but not perfect condition, magnification finds some small edge roughness. The luster is better than most we have seen, this seems to be nearly Magnetite and crystallized on several sides. This was also in the Jeff Glover collection (all labels included ) which was dedicated to Swiss Alpine minerals.

Cerussite (unusual color) with Duftite and Dolomite
stock #18-AX-4-256
Tsumeb
Otjikoto Region, Namibia
7.8 x 6.8 x 4.5 CM (cabinet)
price: $650


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.

Bournonite - unusual non-twinned crystals
stock #18-AX-19-089
Quiruvilca Mine, Santiago de Chuco Province
La Libertad Department, Peru
6.8 x 3.7 x 2 CM (cabinet)
price: $450


Bournonite is so often twinned or in classic "cogs-wheel" form that untwinned crystals are quite rare. This Quiruvilca (Peru) specimen is that unusual sort, here are many Bournonite crystals, some over 1.2 cm but no twins. In fine condition overall most crystals are perfect but with good magnification some small areas of rough edges are found. For this notoriously fragile specie that is impressive. Some bright golden pyrite adds contrast to the dark silver-metallic Bournonite. For some reason the Pyrite at Quiruvilca Mine is often especially bright and lustrous, it seems to be more stable than most and keeps the bright golden color much better than any other Pyrite I know. A fine addition to a serious Sulfide collection

Rhodochrosite with Apatite, Fluorite, and Pyrite
stock #13.1-026
Wutong Mine, Liubao, Cangwu Co. Wuzoh Pref.
Guangxi Province, China
5 x 4.9 x 3.1 CM (miniature)
price: $920


A flat habit rhombohedral crystal of Rhodochrosite sits aesthetically on matrix. Tiny purple Fluorite and Pyrite is also on the front face of the Rhodo adding some character. The matrix has clusters of elongated white Apatites (not visible in the photos) mostly on the backside. These are vividly fluorescent (yellow) in long wave. The condition is excellent and the Rhodo is partly transparent. Better color than is usually seen, this piece was from the earliest finds of Rhodochrosite at Wudong. I do not think any Apatites were found in the later pockets.
