I forgot. Sorry!

The human visible spectrum includes wavelengths from about 390 nm to 700 nm. We cannot see light from below and above such range (which would be UV and IR light respectively). Other animal species can see slightly different wavelengths. But the range that the cameras see must be even more different. Not to mention the big difference of resolutions. So it's no surprise that the photos we get don't match the images we directly see.

As usual, a splendid specimen and a great photo - I guess cassiterite is not easy to photograph. But what are the green/blue areas on the matrix, a copper mineral?

Thank you, Tobi.

Regarding the blue areas, I don't know what they are, but I consider them as negligible. Probably something like Blu-Tack from the previous owner. I'll try to clean them.

PostPosted: Dec 18, 2017 06:35    Post subject: Collection of Carles Millan - Manganite from Ilfeld  

Manganite

Very bright and lustrous, well formed, jet-black prismatic crystals of manganite. The plate has dozens of sharp columns up to 18 mm tall, striated according to the c-axis with the typical rough flat terminations, densely covering the top of an 110 mm x 54 mm x 39 mm massive manganite matrix. Mass: 347 g. I can't see any damage with my naked eye except in the periphery. An old-time European classic from the type locality that set the standard for the species (and still does). Put on sale in the XIX century by the German dealer Dr. Adam August Krantz (1808-1872), as seen in the label that comes with it. He was then one of the foremost mineral dealers in Europe, established in Bonn from 1850 until his death. Wikipedia: https://en.wikipedia.org/wiki/Adam_August_Krantz

Ilfeld, Nordhausen, Harz, Thuringia/Thüringen, Germany.

Finally something new from your collection, Carles :-) And really GREAT news, as it seems: Congratulations to that specimen, you added one of Europe's most desired classics in superb quality to your collection! I have seen many of these famous Ilfeld manganites in German collections, and even many museums don't own a specimen like that. And even with an old Krantz label! Simply fantastic :-)

Tobi, you are fortunate for living at about 200 km from Ilfeld (and Sankt Andreasberg, and Neudorf...). Just one-day round trip and you are able to collect something. For free. Some people at Ilfeld found a rich manganite dump under a 400 y/o oak tree several years ago.

We could always start a series of threads along the lines of "XXXX's most desired classic". If we are talking about Europe, I want a Siderite box!

PostPosted: Jan 28, 2018 12:52    Post subject: Collection of Carles Millan - Tetrahedrite from Peru  

Tetrahedrite, hübnerite, quartz

A crowd of metallic tetrahedrite crystals, the biggest of which is 25 mm on edge, is perched on a large cluster of colorless quartz crystals. The major of these is 86 mm tall, and they are mostly transparent with a somewhat frosted surface making it translucent white. As a little surprise a hübnerite crystal can be spotted just at the geometrical center of the photo, partly overlapping the white main quartz. It is 17 mm long and 7.5 mm wide, and is embedded between quartz and tetrahedrite. When backlit in the right way it shows the typical deep red color. The whole specimen weighs 137 g and measures 92 mm x 61 mm.

Mundo Nuevo mining area, Mundo Nuevo, Huamachuco, Sánchez Carrión Province, La Libertad Department, Peru.

PostPosted: Apr 26, 2018 02:52    Post subject: Collection of Carles Millan - Beryl and muscovite from Pakistan  

Beryl, muscovite

Pale blue transparent beryl crystal, with the usual hexagonal prismatic habit and a complex termination showing at least ten faces. Surrounded by a number of large hexagonal crystals of muscovite. A minor beryl cristal near the right bottom, contacted on the tip. All covering a white compact feldspar matrix. Overall size: 100mm x 88mm x 76mm; main beryl crystal: 38mm tall (visible part) and 20mm wide. Mass: 448g. No damage can be seen with my naked eye and I guess neither with a magnifying glass. The main beryl crystal is perfect and complete 360º.

Shigar Valley, Skardu District, Baltistan, Gilgit-Baltistan, Pakistan.

Photos shot with an LG G6 smartphone and processed with Corel PaintShop Pro X9.
