Osmium is both the rarest precious metal as well as the rarest existing element.

Osmium is mined together with platinum, however, the huge amount of 10,000 tons of platinum ore contains only 30 grams osmium. The separation of the metals is cost-intensive and very complex.

Once the mining of platinum declines, it is no longer possible to mine osmium. At this point, osmium will become even rarer.

Currently the yearly production of osmium amounts 360 kg, but only 120 kg are processed for crystallisation.
