“8.3 x 4.6 x 4.2 cm. A great specimen of "joseite" or possibly "joseite-B” from the Goodhope Mine, British Columbia, Canada. This piece features a beautiful, highly lustrous, brilliantly silvery-white, metallic hexagonal/trigonal crystal group on matrix. As of the time of this writing, it is unclear if joseite-B is actually ever going to be an approved species. As of now it is a 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. Regardless, these specimens are beautiful and incredibly rare, and eventually they will be properly identified and described.
