price: $230
new year 2021
The Quartz localities clustered near Grenoble in Isere, France were sources of some of the most classic and special Quartz specimens in the world. This piece shows well the forms of the slender clear Quartz prisms perched on an altered Siderite "Limonite" matrix. In exceptional undamaged condition, this is from the Dr. Warren Johansson collection, he purchased this in 1984. A nice sized cabinet specimen that shows well the clarity and luster that these are famed for at a reasonable cost for one of these European classics.
SOLD Quartz included by Epidote
stock #SOLD 20.1-880
Cisneros, Mun. de Buenaventura
Valle del Cauca,
Colombia
4.1 x 3.3 x 2.1 (miniature)
price: $150
new year 2021
A light greenish Quartz that is slightly milky is surrounded by and included with slender Epidote crystals. From a remote locality in the Gold mining areas of the Cauca Valley of Colombia, these greenish Quartz and Epidote have trickled out for several years, never many pieces and usually badly damaged. This is from a small lot we obtained in Colombia in 2018 and is far better than usual. The front or display side offers a large window into the Quartz where the Epidote are like a forest or garden scene. The backside has a clean geometric contact and the condition is overall very good, strong magnification does show some very tiny bruises that are not visible by naked eye, for one of these remarkable crystals this as close to perfect as we have seen. A very different and attractive small Quartz.
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.
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
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 crystals are some dark and metallic overgrowths that were at first misidentified as Galena but are likely a Hematite/ Goethite. Overall this is incredible condition, it is even better in person and is an excellent example of the specie and the locality.
