GR1-TLGSiderite : FeCO3

Multiple photos available
Morro Velho mine, Nova Lima, Iron Quadrangle, Minas Gerais, Brazil

Dimensions: 6.4 cm x 3.7 cm x 3.6 cm

6.4 x 3.7 x 3.6 cm. A classic specimen of the gemmy green siderites from the Morro Velho mine in Brazil. Despite the fact that this was a gold mine, it produced some really attractive siderite specimens during the early 1970s. The highly compressed, distinctive rhombohedra of siderite show beautiful sharp, lustrous faces with good internal gemminess. The color is certainly characteristic for the locality. The crystals on this specimen are fine quality for the locality, and the species and are studded with minor marcasite crystals. The largest siderite measures 2.6 cm across. From the collection of the long time, well-known French field collector, Paul Zerfass (Collection #524). Zerfass built this worldwide collection over nearly 50 years, many of which were personally collected. A biography featuring specimens from his collection (along with his face on the cover) is in the May - June 2017 issue of French mineral magazine, Le Règne Minéral. We have a pdf copy of the article for anybody interested in reading it (though it's mostly in French). Just drop us a line and know that you'd like to have a copy.

Multiple photos available
Lime, Baker Co., Oregon, USA

Dimensions: 1.5 cm x 0.8 cm x 0.7 cm

1.5 x 0.8 x 0.7 cm and 1.1 x 0.8 x 0.7 cm. A really cool pair of twinned orthoclase crystals from this remote locale in far eastern Oregon. One of the crystals shows a textbook Baveno twinning habit, while the other shows a good example of the Carlsbad twinning habit. Both of the crystals have gentle translucency when backlit. The faces are sharp, with a pearly hue and really overall the quality is excellent for the species, despite the smaller size. Ex Kay Robertson Collection (#11371). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record).

LAU-6F5Malachite : Cu2CO3(OH)2

Sacramento pit, Sacramento Hill, Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA

Dimensions: 3.2 cm x 2.7 cm x 2.3 cm

3.2 x 2.7 x 2.3 cm. An attractive and fine specimen featuring velvety green malachite which has formed a handful of "sword"-shaped pseudomorphs after preexisting azurite with minor attached matrix. The largest pseudomorph measures 2.0 cm. This is classic material from the Sacramento Pit/Sacramento Mine. The original Sacramento Shaft started in 1904 and produced high grade ore until 1931. The Sacramento Pit started in 1917 and both localities were consumed by the famous large Lavender Pit in 1950.
