Something like the absolutely flawless native crystalline, semimetallic tellurium on sylvanite crystal some lucky motherfuck has in their element collection:
Ain't that simply just gorgeous!?!
I'd actually pay quite a bit for that particular piece, but I doubt its for sale. Lovely or what? that crystal, the bright, shining silvery-white part is native elemental tellurium 'metal' (in quotes because Te is actually one of the metalloids, or semimetals, similar to things like elemental silicon, a couple of the allotropes of arsenic, black phosphorus, one of the allotropes of antimony, boron and germanium.)
That crystal is one of the finest I have ever seen of tellurium, near flawless gem quality to totally flawless. Although one does not want to wear it in contact with the body itself, because absorption of Te induces a condition known as tellurium breath, due to offgassing volatile alkyl tellurides such as dimethyl telluride and dimethylditelluride, that possess such a virulent stygian abominable stench that people afflicted with Te-breath have apparently committed suicide, because society ostracised them and they couldn't go out in public whilst they emitted the filthy stink. Clothes have to be burnt, because they reputedly smell too foul to otherwise bin or dispose of, and even books they touched in uni had to be retired from service, due to minute traces of the tellurium metabolites coming out in traces of sweat from the reader's fingertips.
But, that despite, that native Te is beautiful beyond words.
