|---|---|
| Description | This specimen is 4 cm across. It contains rutheniridosmine, a natural alloy of ruthenium, osmium and iridium in which iridium dominates, mixed with gold-colored sulfides. When fresh, ruthenirodosmine has a silver-white metallic appearance. It occurs in ultamafic rocks and in placers derived from such rocks. Rutheniridosmine, in the past called iridosmine or osmiridium, may contain minor amounts of platinum, rhodium, and other metals. |
