Iridium

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Ir,Os,Ru)
Hardness:
6 - 7
Crystal System:
Isometric
Natural iridium often contains distinct amounts of Os, Ru or Pt.
The definition of iridium now incorporates old "osmiridium" and "ruthenosmiridium" mineral species (all have Ir as the dominant element).

See also (hexagonal) rutheniridosmine.


Note: The type locality is not determined.

Varieties of IridiumHide

AurosmiridiumA solid solution of Gold and Osmium in cubic Iridium.
Originally reported from Urals Region, Russia.
OsmiridiumA variety of Iridium rich in Osmium.
Originally reported from Urals Region, Russia.
PlatiniridiumA variety of Iridium rich in Platinum.
RutheniridiumOriginally a ruthenium-rich variety of Iridium, however as all natural Iridium contains ruthenium this name is now regarded as synonymous with Iridium.
RuthenosmiridiumA variety of iridium rich in ruthenium and osmium.
