Everybody knows about Milpillas secondary copper minerals, but this locality is not well-known by the complex pyrite crystals coated by bornite. We propose one of the few specimens I have seen. In this sample we can see the dominant forms of the cube, but also the octahedron, surrounded by trapezohedron and possibly the dodecahedron on edges. Bright and well disposed in a solid matrix. It is a true crystallographic gem.

Size: 8.0 x 6.5 x 5.7 cm.
Main crystal: 18 x 18 mm.

An amazing rutile specimen with an exceptional quality for the locality and for the species. The famous rutile specimens of Kapudzhukh in Azerbaijan are already a classic. It is said, they appeared during the 90s, for only a period of two years. This specimen shows perfect faces, first and second order twins and dipyramids, and a more than outstanding definition.
According to explained by Rob Lavinsky, a limited number of pieces were collected during this short period. They were send to United States, at the hands of Bill Larson, through a former official of the KGB, nicknamed "Niki the Tank", who got into mineral collecting and dealing after the Wall fell. Honestly, this is one of those pieces that you dubt to keep or come off it...

Specimens of Bulgarian pyromorphite appear very rarely and collectors ususally don't lose chance to get them. In this fine sample we have a matrix partially covered by pyromorphite crystals showing the hexagonal prism and pinacoidal defined faces. Color is one of the characteristics of these pieces, a brown tone, slightly reddish, with some zoning. A magnificent chance to get a specimen from this mine.

The kamotoite-(Y) are the intense yellow crystalline sprays, with individual flat-laying crystals to 5 mm. brilliant and transperent. In the same sample we can observe probably a small vein of yellow to orange brilliant uranophane. Kamoto is the Type Locality for the species. A very rare uranium and ytrium mineral from Katanga.

Group of sharp aegirine crystals in parallel growth, with striated prismatic shapes and sharp terminals. Good brilliance and very dark green, almost black. With a small quartz and feldspar matrix.

Size: 6.5 x 4.4 x 4.0 cm.
Main crystal: 55 mm.

Group of smoky quartz crystals where one stands out for its development, brilliance and a very uniform smoky tone. Accompanied by prismatic black aegirine crystals, bright and with defined faces and edges. On a matrix of feldspar (microcline). Very aesthetic piece.

These specimens of Peruvian arsenopyrite stand out for their excellent luster and perfection of its crystals. With the camera I am not able to capture its real beauty. On a sulfide matrix we can enjoy hundreds of arsenopyrite crystals, prismatic, with defined terminal faces, rather than well-defined. They're accompanied by chalcopyrite crystals with dull luster, but gold tone, also well-defined and twinned. Brilliance and quality. A novelty of Sainte-Marie-aux-Mines 2016.

A classic specimen of Mt. St-Hilaire combines a group of good sized analcime crystals with trapezohedral faces, well defined and interpenetrating each other. With some sérandite crystals, well defined and showing an excellent bright orange color. It is accompanied by aegirine, green fibrous actinolite and crystals of manganoneptunite with a dark brown color, and probably accompanied by thorian britholite-(Ce) (not perfectly identified). An indispensable classic of mineralogy. We will send analysis to the buyer.

Really fine specimen, with good size, for this rare species. The balangeroite is a magnesium, iron anfd manganese silicate, only found in a few places worldwide. The serpentine Poggio San Vittore quarry, which were the best samples has been found and it is the type locality for the species, is abandoned since 1990.
The mineral usually appears included in the serpentine matrix and only few fibers are aerial. In this specimen, fibers are totally aerial and with an unusual length. A definitive piece, from the TL for selected displays.

Size: 12.4 x 6.0 x 5.5 cm.
Main crystal: 95 mm. fibr.
