Galena - spinel twinned
Krushev Dol Mine, Madan, Rhodope Mts.
9.5 x 4.8 x 3,7 CM (cabinet)
new year 2021
A killer Galena with very well defined geometric structures which are the flattened Spinel twinned crystals. Remarkably there is no damage and the luster is super metallic. From a remarkable find in 2010, this comes from a single pocket that had especially well developed sharp edged Galenas that were sprinkled with some Quartz crystals. The look is similar to some Spinel twinned Galenas from Dalngorsk but also distinctly unique. These are more tabular crystals with thin sharply crystalized edges. These have been described by some as "star wars" Galenas. they do look like spacecraft structures in person. We have been keenly interested in the Galenas from Bulgaria for years, this particular find and the few specimens of this caliber are to my taste the best.
Celestite on Calcite
Cave-in-Rock, Hardin County
3.9 x 2.6 x 2.3 CM (small miniature)
new year 2021
A small but very esthetic specimen from the prolific Fluorospar region of Southern Illinois. Ex. Larry White collection, the Celestite (or Celestine for many) is a terminated flat prism set on light yellow Calcites. Unusual in its composition, this piece has considerable display impact despite the small size and is in excellent condition. This zone produced many thousands of great Fluorite specimens but very few good Celestites were saved.
Bright lustrous Linarite crystals on a contrasting matrix. From the Grand Reef Mine, this specimen has numerous species on board. The Gearksutite is is present as porcelaneous green masses. Linarites are very sharp and transparent with typical vivid color. A modern USA classic locale, this is a mid sixties vintage specimen.
Faden Quartz (gemmy yellow)
Barranc del Cargoi, Arestul Llavarsi, Pallars Sobira, Lerida
5.2 x 2.4 x .4 CM (small cabinet/ large miniature)
new year 2021
A perfect, gem-clear yellow Quartz crystal that has tabular form and a distinct faden line inside. Excellent, undamaged and with textbook form. Certainly a very choice faden from anyplace, this important small locality has alpine type veins and distinctive tabular forms. The color is a nice yellow to light orange at some angles, this seems to qualify as a Citrine. A clean floater, this is doubly terminated and the nicest specimen I have seen from this interesting locality.
A historic specimen of Lazulite crystals well-exposed on a small matrix. The second photo includes the original label from Charles U. Sheppard Jr which indicates this was from a brief period of mining at this site specifically for mineral specimens. Sheppard's father was one of the great early USA mineralogists, he studied this deposit and published in 1856. His son (Jr.) later was a part owner and mined this locality for the international specimen trade and exchange with institutions. Sheppard Jr died in 1915, though the specimen is likely over 150 years old. This Lazulite thumbnail has several crude crystals on it the largest and best is 1.6 CM tall and covers much of the front or display side. This locality produced a very few exceptional world class Lazulite; this one is not that exceptional but is certainly above average and has the rare original label that dates back to one of the first specimen mining operations in the USA. An affordable and nice classic.
A killer Beaverite in a highly esthetic and important specimen. This fairly rare Lead Iron and Copper specie is almost never in display grade specimens, it is usually just tiny crystals that are attractive only under the microscope. The Beaverite is in green and yellow botryoidal zones but also is in the rare red color balls and crystals which are dominant on this piece. The Beaverite is nicely contrasted with two generations of Calcite, the smaller being glass clear rhombs with the Beaverite visible through the crystals. Microscope exam finds areas of reddish Jarosite and what looks like Chenevixite in olive-green needle crystals. The first photos show what I consider to be the front as the Calcite make a great contrast, but the Beaverite is on all sides and the back (last photo) is super rich also. No matter the display side chosen this is a world class specimen. Ex John Marshall collection, I have not seen any better.
SOLD Schorl on Microcline
stock #SOLD 21.1-050
Hohenstein Massif, Omaruru District
8.7 x 7.6 x 3.2 CM (cabinet)
Sharp, lustrous Schorl crystals are scatted on a crystalized Microcline matrix. The Schorls are in several habits, well terminated with striated prism faces. In undamaged condition the specimen is well composed and is a choice example for this amazing locale. This was obtained directly from a group of "Small Miners" on the flanks of the Hohenstein just after it was extracted with laborious and careful hand work. The Small MIners have been one of the best sources of very nice yet affordable minerals today.
stock #SOLD 20.1-898-(ZSROS4106)
Silver Bill Mine, Gleason, Dragoon Mts. Cochise County
6.7 x 5.6 x 4.3 CM (cabinet)
Royal blue, velvety Rosasite fills an open cavity in this Gossan matrix. There are other areas of Rosasite on the specimen but the first images show the darker vivid blue that is much less common than the pale blue varieties. From The Silver Bill Mine of Arizona, this is well-known as a past producer of some attractive lead and copper minerals, and has become a classic USA locality. This is especially vibrant and a very good example for the region.
