Ferberite, mica
Group of ferberite crystals with mica. Overall size: 43 mm x 25 mm. Weight: 77 g. Purchased in 1966 from Francesc Coma, Barcelona.
Had to be repaired long time ago after an unfortunate free fall journey to the floor caused by the force of gravity. The curvature of the main crystal must be natural, not due to the repair, that is undetectable.
Panasqueira Mines, Covilhã, Castelo Branco, Portugal.
This specimen is no longer part of my collection.

Carles, your garnet from madagascar could be from Ialamitana in Antananarivo province. I'm not sure, but the appearance of the crystal and the matrix could indicate that.
Glückauf!

I've taken note of your opinion in the specimen record.
Thank you!

Hello Carles,
I have enjoyed seeing some of the specimens in your collection. Your sphalerite specimen from Picher Oklahoma is very nice. Although calcite was a common gangue mineral throughout the district, the sphalerite crystals on your specimen do not appear to be on calcite, but on a brecciated gray chert. This chert formed the matrix for most of the specimens produced from this famous lead/zinc district.
Keep the pictures coming!
Regards,
Michael Shaw

Hi, Michael!
You must be right. I've just tested the matrix for hardness and it cannot be scratched with a steel knife, the opposite being true, so it cannot be calcite.
Thanks for your comments!
