Osmium leads the list of the rarest elements among the non-radioactive elements and usually occurs together with platinum. Osmium can also be found together with ruthenium, palladium and rhodium.

The main deposits of osmium are in Borneo, Japan, North and South America, Tasmania and the Ural Mountains. In general, deposits are divided into primary and secondary deposits. Primary minerals include iron, chromium, copper and nickel ores containing osmium. Secondary deposits consist of platinum-group metals combined with osmium.

The most common alloys are iridosmium and osmiridium, which both occur naturally.
