Joseite-B (rare Te sulfide) Vajdak Coll.

Item Description

Joseite-B is a rare questionable/doubtful species, according to the IMA. The bismuth, tellurium sulfide is named for its relationship to joseite (same elements with different amounts) and is possibly just sulphur-rich pilsenite (bismuth tellurium). In any case, whichever it is, it is hard to obtain. Bright metallic silver-white flakes are clustered on the crest of the quartz-rich matrix. This very rare example and specimen is from an uncommon gold mine in British Columbia. Ex Josef Vajdak Collection.
