Fluorite on Quartz
stock #15.1-1010-SM0
De'an Mine
Jiangxi, China
5.9 x 4.8 x 3.3 CM (small cabinet/large miniature)
price: $330
Spring 2014

A super sharp, well exposed and choice Fluorite on Quartz matrix. The main octahedral crystal is 2.6 CM across the axis and contrast nicely with the matrix. An older piece from the first wave of specimens produced at Dean mine, this was in the Charles Noll collection. These were exposed by dissolving the enclosing Quartz with hydrofluoric acid, and tricky and dangerous task. This one is especially esthetic and has some zoning. No damage, the Fluorite looks really fine from all angles. Although a lot of these did come out in the 2005-7 era, this quality was never very common.
Calcite with Aragonite- classic locale
stock #16.1-1275
Southwest Mine, Bisbee, Warren District, Mule Mts, Cochise Co.
Arizona, United States
8.8 x 4.9 x 4.8 CM (cabinet)
price: $225
Spring 2017

A choice Bisbee specimen with delicate needle crystals of acicular Aragonite perched on balls of Calcite. From the Southwest mine, this area intersected many voids formed by slumping of oxidized sulphide ore. These voids allowed many secondary Carbonate minerals to form in esthetic growths. As the mining entered these voids some fine specimens were saved. In perfect condition and with good luster.
Carrollite with Calcite
stock #A-19-257
Kamoya, Kambove, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
4.7 x 3.1 x 3.2 CM (miniature)
price: $190
Spring 2017

Carrollite with very bright metallic luster on a nice miniature specimen. There have been no new finds of Carrollite for a few years now, but for a time the Kambove mine was a prolific source for the best specimens ever found. This bright miniature has sharp crystals to 1.3 CM size, there are some contacts and bruises seen on some angles but they are relatively small. More perfect, larger specimens are now trading for many thousands, this piece is a lot more modest but still has top luster and nice form. An affordable alternative that looks much better than the mine run.
Beryl Var. Emerald- Trapiche form cabochon
stock #16.1-1268
Muzo Mine
Boyaca, Colombia
1.4 x 1.1 x .4 CM (thumbnail)
price: $725
Spring 2017

A choice example of a Trapiche Emerald with the rare and very desirable transparent hexagonal center form. Cut from sections of the Emerald crystal with the C axis in the middle these are unique to this area in Colombia, and present a remarkable natural six-armed structure. Far above average for rich green color, the transparency is also first rate. Weight at 5.5 Carats, this grade would usually be priced from 300-400 plus per carat when available. From a small private collection of trapiches, this is from finds several years ago.
SOLD Rutile on Hematite- Epitaxial twins
stock #SOLD 16.1-1269
Novo Horizonte
Bahia, Brazil
4.3 X 3.4 X .6CM (miniature)
price: $0
Spring 2017

Rutile stars are one of the most amazing mineral habits and when they grow from a flat crystal of Hematite it is especially impressive. This is a good example, very nice luster and in good condition despite being so delicate. The find at Novo Horizonte has given us a nice array of these, a perfect definition of the word epitaxial.
Adamite- Cuprian ex Marty Zinn
stock #12.1-262
Mina Ojuela, Mapimi
Durango, Mexico
6.8 x 5.3 x 3.2 CM (cabinet)
price: $400
Spring 2017

An outstanding Ojuela Adamite, with sharp glassy undamaged crystals on contrasting matrix. This is not the crumbly type gossan but a solid specimen with the Adamites well protected in a vug. In person the color is a little deeper and more intense than in the photos. This quality has not been seen for a few years. Former Marty Zinn piece, choice.
Calcite- classic British
stock #16.1-1270
Bigrigg mine, West Cumberland Iron field
Cumberland, Cumbria, England
3.1 x 1.7 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $140
Spring 2017

A clear sharp single scalenohedron from the famed Bigrigg mine. From an older European collection this is at least 80 years old but likely much older. There is a number attached that could be removed if desired. Quite clean by naked eye but some contacts and rough bits found with magnification, all under 1mm. Not perfect but looks it, and not expensive as is often the case with these old
Cerussite Reticulated twins -classic USA Locale
stock #A7-551-548
Mammoth Mine, Tiger, Arizona
Arizona, United States
4.9 x 4.3 x 3.1 CM (miniature)
price: $440
Spring 2017

An excellent Tiger Cerussite with classic form, formerly in the Larry White collection, obtained from Shields Flynn. In good condition overall, there is also some chipping damage that can be seen. These bruises are forgivable on such a well formed classic Arizona piece, especially from Tiger. Essentially all of the specimen is Cerussite in twinned habit, there is a small zone of adhering matrix and a painted number from the White collection. Q
