Superb old time specimen of the silver and gold telluride mineral Sylvanite. The crystals form flattened, bright metallic graphic intergrowths known as 'Schrifterz'. This specimen was from the collection of a German professor who emigrated to the U.S. and comes with an old Wilhelm Maucher label that dates the specimen back to at least 1936, and the specimen likely dates back to the 1800s.

Dravite from Mwajanga, near Komolo, Tanzania [db_pics/pics/tz508a.jpg] Dravite from Mwajanga, near Komolo, Tanzania [db_pics/pics/tz508b.jpg] Dravite from Mwajanga, near Komolo, Tanzania [db_pics/pics/tz508c.jpg] Dravite from Mwajanga, near Komolo, Tanzania [db_pics/pics/tz508d.jpg]

Well terminated single Dravite crystal from a small recent find that produced these incredibly colored crystals. The termination has an intensely colored red/pink coloration. I understand there were only about 30 crystals found and this one has the best quality in terms of color and crystal form, with many showing varying degrees of surface etching and pitting. This crystal has smooth crystal faces and flat, smooth termination faces with relatively minor amounts of etching.
