Dany, many thanks for your comments. You are very fortunate to live in Valais/Wallis. I know that canton, especially Zermatt.

Fluorapatite Ca₅(PO₄)₃F, siderite FeCO₃, quartz SiO₂

Description: Fluorapatite crystals of hexagonal shape are disposed on a matrix of hyaline quartz crystals and accompanied by siderite. The fluorapatite crystals are translucent to transparent with a very uniform, nice pink color and very well-defined hexagonal faces, truncated by the pinacoids and faces of the dipyramid. The color of these crystals varies a little depending on the type of light; it is a bit pale in daylight and more saturated under incandescent lighting. It is accompanied by well-defined rhomboedral siderite crystals with a very aesthetic green-brown color, arranged very aerially on the specimen. A specimen from a recent find in the Kami mine; it is in excellent condition.

Dimensions: 74 mm x 52 mm.
Mass: 87 g.
Locality: Kami Mine, Ayopaya Province, Cochabamba Department, Bolivia.

Another wonderful specimen, Carles!
Everything in this piece represents your good taste in minerals: The shape, the quality and the mix of colours, forms and textures make this a perfect specimen for any advanced collector!

Gorgeous piece, congratulations :-)

Old specimen, better photos

Copper Cu

Description: The specimen consists of a spinel-twinned single crystal with a lovely natural deep black oxidation patina, with 3-dimensional idiomorphous complex octahedral-trapezohedral {111}{211} sidecar crystals growing off of its length and stacked one on top of another. The crystals show very well-defined faces and edges, which is somewhat unusual for this species. I think the rear dark patina might be tenorite (CuO) rather than cuprite. Field collected in 2009. Purchased in Munich 2015.

Dimensions: 63 mm x 10 mm. Major crystal size: 8.5 mm wide.
Mass: About 13 g.
Locality: Itauz Mine, Dzhezkazgan, Karaganda Region, Kazakhstan.
