Selenium is little known other than for its use in dandruff shampoo and as a vitamin supplement of dubious medical value… hardly a glamorous claim to fame. However obscure it may be it is very attractive in both its red and glassy black forms. Here we have a specimen of the latter with crystalline pieces that give off a sultry gleam like some kind of super-sexy chocolate.
