Don, Am, Enrique, Tobi, and Michael:
I express my sincere gratitude for the time you have dedicated to writing these very kind posts.
But sincerely, I don't think this subject is important enough to keep going forever.
Thank you!
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!

Posted: Jul 12, 2024 04:15 Post subject: Collection of Carles Millan - Copper from Itauz Mine
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.

I think it was a good idea to take some better photos, this specimen deserves them. Actually copper is a mineral that doesn't attract me that much because most of the specimens are just amorphous masses. But I love copper specimens that show good crystalline structures, and your piece is a wonderful sample. The way it is built from several crystals stacked on each other, simply beautiful and unique!

I completely agree with you, Tobi. A mineral with well-defined (idiomorphous) crystals made of a native metal has an extra value. Silver wires that are so expensive on the market (with the wow effect) are not something I like.
And thank you once again for posting your comments.

And I always thought I am the only serious mineral collector who doesn't like wire silver ;-) Even as a German who loves German minerals I never was attracted to the legendary silvers from Saxony. In my personal taste, your copper posted above is much more attractive.

I am a serious collector too and am not attracted to silver wires at all, either. What's more, I cannot understand why so many expert (and rich) people pay up to 6 figures for them. But I think everybody has the right to spend their money the way they want.
