JVC-QT1Arsenopyrite : FeAsS, Pyrite : FeS2

Multiple photos available
Huanzala Mine, Huallanca, Huallanca District, Bolognesi Province, Ancash Department, Peru

Dimensions: 10.3 cm x 9.6 cm x 5.7 cm

10.3 x 9.6 x 5.7 cm. Dense radial sprays of splendent, steel-gray arsenopyrite prisms with a light yellow appearance dramatically cover the large undulating specimen from the Huanzala Mine. The prisms reach 2.2 cm and have sharp chisels terminations. The prisms rest on a thin bed of tiny, splendent, brassy pyrite pyritohedrons, which adds more character to this very rich large combination. Arsenopyrite specimens of the size, richness and crystal style are very uncommon from this noted locale. Ex Ted Bartels Collection.

UHA-3GTFluorite : CaF2

Multiple photos available
Felix Mine, Azusa, San Gabriel Mts, Los Angeles Co., California, USA

Dimensions: 5.8 cm x 4.2 cm x 2.3 cm

5.8 x 4.2 x 2.3 cm. Rare powder-blue fluorite from this well-known urban Los Angeles locale. Most fluorites recovered were green. Stepped-growth cubes, to 1.1 cm, are gemmy to translucent, have satin lustre faces and are aesthetically clustered on the matrix. These fluorites were collected by the Gochenour brothers in the early 1990s, and are seldom available even within California. The vein was very small, and hard to work. It was tucked into a now-inaccessible canyon in a suburban development within the greater Los Angeles area, and can be considered a mineral from a very urban locale. Purple fluorescence. Ex Kay Robertson Collection # 12354 and acquired from the Gochenours in 1995 at the Costa Mesa Show. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Velt" November-December 2017). An excellent, rare blue color California fluorite.

The broken/contacted tips reveal the hollow tubes where the precipitating copper-rich fluids flowed, add character. Ex Kay Robertson Collection # 7433 and acquired in the mid-1970s. The locality information is written in her box. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017). Rare, old-time Utah malachite.
