Dolomite cast with Calcite
stock #16.1-308
Tsumeb
Otjikoto Region, Namibia
4.3 x 3.4 x 2.2 CM (miniature)
price: $120
new year 2021

One of the many odd but amazing things found over the years in Tsumeb were hollow Dolomite casts. These are replacements or encrustations of earlier minerals which have since disappeared. Sometimes the casts have then been overgrown with other minerals as well. The forms are quite diverse and entire collections have been made of the many shapes, colors and associations. This miniature cast is a pale green color and is overgrown with gem clear, colorless Calcite rhombs. The walls are typically thin and the whole specimen is a delicate hollow structure. Looks great from any angle, an attractive example of a mineral oddity.

Epidote
stock #14.1-380
Capelinha
Minas Gerais, Brazil
4.6 x 3.5 x 1.4 CM (miniature)
price: $300
new year 2021

A pair of fine, sharp and lustrous crystals of Epidote from Capelinha in Brazil. Most of the Epidote we see from Brazil is a more fibrous habit, this prismatic specimen is the best formed I have ever seen. Textbook perfect crystals with well-defined terminations and on the backside a few clusters of small Quartz crystals. Overall in excellent condition as seen, the faces are either well-striated or perfectly flat, mirror-like and brilliantly lustrous. The sharpness and quality of this could easily be confused with a fine Alaskan Epidote.

Fluorite on Schorl
stock #AX-14-159
Erongo Mountain, Karibib
Erongo Region, Namibia
6.8 x 5.3 x 4.6 CM (cabinet)
price: $790
new year 2021

Colorful zoned Fluorite crystals are perched on a jumble of lustrous Schorl crystals from Erongo. Close exam of the Fluorites shows they are also included by dark tourmalines some of which have areas of transparency. The Fluorites have some spots of deep purple set in a light blue background. These crystals are somewhat etched and show some spinel twinning as well. The Schorl crystals are in two habits some with the fibrous habit faces and others with prismatic forms. All are quite lustrous and with two different termination types. Overall very esthetic and striking specimen from a find in 2018. The pegmatites of Erongo have given up some remarkable pockets over the years many of which were unique having unusual habits and forms not seen in any other. We have not seen any more recent finds of this style.

Calcite with Fluorite
stock #20.1-256-(1080)
Denton Mine, Harris Creek Sub District, Hardin County
Illinois, United States
6.8 x 4.9 x 3.8 (cabinet)
price: $330
new year 2021

A southern Illinois classic, a mass of transparent, gemmy Calcite crystals are the sparkling background to some small purple to blue Fluorites. The bright luster of these Calcites are hard to appreciate in photos but in person the visual impact is strong. This choice Denton Mine specimen is from the collection of Les Hitchings which he obtained in 1992, from the last period of mining there which produced some exceptional Calcites.

Anglesite - large transparent crystals
stock #16.1-616
Tsumeb
Otjikoto Region, Namibia
4 x 2.8 x 2.6 CM (miniature)
price: $850
new year 2021

Blocky habit colorless, transparent crystals of Anglesite with a tiny amount of Sulphide adhering to the edges. In excellent condition there are several complex face modifications seen on close exam and a few inclusions that are likely Galena. The transparent crystals have internal iridescent "rainbows" and the luster is bright and glassy. Anglesite crystals are known from many Lead mines worldwide but only a very few localities have produced such fine large crystals, and Tsumeb is high on the short list. A very fine undamaged and esthetic example of the specie and for this habit.

Pyromorphite with partial Galena pseudomorphs
stock #20.1-877
Daoping Mine, Gongcheng County, Guilin Prefecture
Guangxi Province, China
5.7 x 3.7 x 3.5 CM (cabinet)
price: $1350
new year 2021

A very rich and super esthetic Pyromorphite from the great finds at Daoping in Guanxi, China. Two generations of well-formed Pyros have slightly different hues of green and all have excellent bright luster. The larger crystals are free standing and reach 1.3 CM. Terminations of the larger crystals are both hopper habit and prismatic with the larger being more the cavernous hoppered type. On a few sides of these prisms there are secondary alterations of rare pseudomorphing to a Galena sheath which is the overgrown by a third generation of extra bright green Pyro. This phenomenon is very rare worldwide, but well-known from just a few European locales and ultra rare from China. Overall this is incredible condition, it is even better in person and is an excellent example of the specie and the locality.

Topaz on Microcline with Quartz
stock #17.1-524
Hohenstein Massif, Omaruru District
Erongo Region, Namibia
6.6 x 4.7 x 4.3 CM (cabinet)
price: $230
new year 2021

Small, perfect, gem clear Topaz crystals are perched on a Microcline crystal that is perched on a Smokey Quartz crystal. This association of species is a classic assemblage and very well-presented in this Erongo specimen. The condition is good, with some contacts and edge roughness on the matrix, the Topaz are fully perfect even under strong magnification. This was excavated by the "small miners" collective on Hohenstien in 2017.

Cuprite - Classic locale and form
stock #20.1-876
Chessy Copper Mine, Chessy-les-Mines, Villefranche, Rhône
Auvergne-Rhône-Alpes, France
1.3 x 1.1 x 1 CM (thumbnail)
price: $390
new year 2021

A perfect thumbnail crystal that is complete all around and has textbook perfect hoppered faces. The Cuprite is coated with Malachite as is typical from Chessy. This locality is famous, it is one of the oldest and most classic of European mineral localities. This example is unusually perfect, undamaged with no contacts or missing parts. This was in the collection of Terry Szenics who is well known for excellent taste in minerals, especially copper species.
