Fluorite, hübnerite, quartz

Pale green octahedral fluorite crystal, complete all around, on a matrix of quartz, accompanied by hübnerite. Overall size: 65 mm x 65 mm x 56 mm. Fluorite crystal size: 35 mm on edge. Weight: 202 g. The crystal of fluorite is green in the inside and almost colorless in the outer part, near the surface, which says something interesting about the history of the specimen. With strong rear illumination the hübnerite shows red translucency.

Huayllapon Mine (Huallapon Mine), Pasto Bueno District, Pampas, Pallasca Province, Ancash Department, Peru.

Tetrahedrite, pyrite, quartz

Group of near two dozen, metallic gray color tetrahedral tetrahedrite crystals set on a pyritohedron of pyrite. Overall size: 65 mm x 51 mm. Longest tetrahedron edge: 12 mm. Longest pyrite crystal edge: 25 mm. Weight: 143 g.

Actually a member of the series tennantite-tetrahedrite. So it might be from a Sb-rich tennantite to an As-rich tetrahedrite, somewhere between.

I might be from a Sb-rich tennantite to an As-rich tetrahedrite, anywhere between.

Mundo Nuevo Mine, Huamachuco, Sanchez Carrion Province, La Libertad Department, Peru.

Hi Carles,

i suppose 1274 grams of assembled pyrite crystals are quite fragile ... How do you prevent this specimen from breaking apart? Is it fixed somehow? Or does the polycyanoacrylate make it stable?

Cheers!

I do nothing at all to prevent it from breaking. People at the mine have much experience with polycyanoacrylate, and are using a special kind of this glue that supports, they say, up to 300 kg/cm˛, which is a lot. For several years this pyrite had been standing in my showcase in the least stable position, only one cube in contact with the base, the others directed upwards, as you can see in the photo below, without any problem of breaking apart and dropping. However, it is currently resting in a much more stable horizontal position, as seen above.

But 1274 g is nothing compared with the 3.9 kg that this other very similar specimen weighs, also in my collection: http://www.mineral-forum.com/message-board/viewtopic.php?p=2789#2789

Thanks for your interest.
