"Osmium is an 'extra-terrestrial mineral' - meaning a mineral not naturally found on this Earth as it has originated in outer space. Such materials include those found in cosmic dust and meteorites - Iridium and Osmium are two examples of extra-terrestrial minerals arriving in meteorites, and being extremely rare on earth, with only tiny amounts mined annually. Armantium is also very rare, and arrives on earth in the same manner as Iridium and Osmium.", Tony explained.
