Fluorite - purple, blue, yellow etc
stock #18-AX-18-064
Rosiclare Level, Denton Mine, Haris Creek Sub-district, Hardin County
Illinois, United States
8.1 x 6 x 4.8 CM (cabinet)
price: $490
Worldwide mix summer

A choice, sharp old Rosiclaire, Illinois Fluorite dusted with a little sparkling Quartz. Very good translucency, this backlights very well and shows multiple internal colors. In sunlight or daylight balanced light sources this is a nice blue with hints of yellow and some red internal color. Incandescent lighting turns this a more purple color. Overall in very good condition, a close exam finds some very tiny edge bruises but these are clearly not distracting yet keep the price low. Better in person, strong display and now getting very hard to find this quality at reasonable costs.
Cordierite - classic locale
stock #8.1-293
Richmond Soapstone Quarry, Cheshire County
New Hampshire, United States
6.2 x 4.2 x 3.7 CM (cabinet)
price: $225
Worldwide mix summer

A classic Northeastern US Cordierite crystal on matrix 4.2 CM tall. The termination is the usual flat top habit but with some edge modifications. Far better than most of these, the crystal is well defined somewhat sharp and unusually distinct but also clearly a bit crude as are these old Cordierites. . Nice mahogany brown color, good size and waxy luster on all the faces. Choice yet affordable example not often available in this quality.
Beryl V. Emerald on Calcite
stock #8.1-223
La Marina Mine, Pauna
Boyaca, Colombia
3.3 x 2.1 x 1.5 CM (small miniature/ large thumbnail (toenail))
price: $450
Worldwide mix summer

Fine, deep color Emerald crystal nicely perched on crystalized Calcite. From the La Marina Mine, which is famed for Apatites and Euclase but only rarely are specimen Emeralds seen from here. No repairs, the hexagon of Beryl has some etched faces and one one edge a contact but otherwise it is a very choice little gem crystal on classic Colombian matrix. It has gotten very hard to source Emerald specimens in Colombia that are not color enhanced, repaired or priced at crazy levels. This is a very reasonable and attractive peice.
Rhodochrosite on Galena and Acanthite with Fluorite
stock #18-AX-22-109
Wudong mine, Liubao, Cangwu Co. Wuzoh
Guizoh, China
6.6 x 5 x 3.8 CM (cabinet)
price: $560
Worldwide mix summer

An early find Chinese Rhodo with a deep rich red color set on a mix of Sulphides including Galena, Acanthite and Sphalerite. The early finds of Rhodochrosites from this region were associated with Silver minerals and sometimes native Silver as well. Later finds were much larger but did not have any Silver species. This has a good amount of Acanthite (Silver Sulphide) crystals and Silver rich Galena with melted look. The contrast is excellent and the Rhodochrosite crystals reach 2.9 CM. No more Rhodos are being found and this is a choice example of the earliest type from the upper zones.
Cerussite -fine silky luster.
stock #18-AX-18-051
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oriental Region, Morocco
5.7 x 4.3 x 3.2 CM (small cabinet/large miniature)
price: $450
Worldwide mix summer

A remarkable and fine Cerussite from Touissit with at least 3 generations of crystals and no matrix. The largest are the silky type twins that are optically transparent from some angles and almost opaque from others as they have a "cats eye effect". These contrast with both a black druzy (heavily included by Galena) and small colorless Cerussites. Remarkably this is fully undamaged and pristine from all angles. Touissit is sadly long closed but did in its day produce some of the worlds best Lead secondary minerals and a few of these unique silky luster Cerussites,. This is a very choice example from any angle, and better in person.
Quartz v. Herkimer
stock #18.1-292
Middleville, Herkimer County
New York, United States
8.3 x 6 x 7.1 CM (cabinet)
price: $250
Worldwide mix summer

A blocky matrix with druzy Quartz hosting several very clear, undamaged Herkimer type Quartz. The diamonds are mostly colorless but a few are the golden type, and all are very clear and lustrous. The largest crystal has a very big internal bubble cavity that holds unusual worm like petroleum inclusions. These are vividly fluorescent and have three distinct colors. A fine and impressive cabinet piece that is especially interesting under the microscope.
Arsenopyrite etc -
stock #8.1-170
Yaogangxian Tungsten Mine, Yizhang County
Hunan, China
8.1 x 6 x 5.8 CM (cabinet)
price: $420
Worldwide mix summer

A very unusual style of Arsenopyrite from the famed Yaogangxian mine. A small amount of Muscovite matrix and associations of Fluorite (small clear purple crystals), Quartz and Calcite are typical in these multi specie specimens, but by far the majority is Arsenopyrite. Unlike the usual silver color, this has the bronze-golden hue that was only found in one zone about 15 years ago. Chipping and bruising on the outer edges is clearly seen but all the main crystals are intact and very sharp. As well as the unusual color, several crystals have unusual habits although most of the largest crystals are more usual forms most of which are in parallel position. Despite the edge damage this is a choice piece.
SOLD Prehnite and Epidote
stock #SOLD 18.1-290
Sadiola Mine
Kayes Region, Mali
10 x 8.4 x 5.8 CM (cabinet)
price: $0
Worldwide mix summer

One of the best (and largest) mineral finds of the past two decades has been the Prehnite from Mali. These have been affordable and attractive, we hope this will continue for a while longer. The most desirable specimens have the Prehnite balls well separated in three dimensional arrangements, and offset by dark Epidote crystals. This piece is of that sort, a blocky matrix hosts bright green balls up to 2.3 CM, well above and outside the matrix. The Epidotes are mostly complete but some small chipping exists. There are a lot of these Mali specimens in the mineral market at reasonable prices, it is a great time to select a choice one.
