Description: Osmiridium crystals - over 1 troy ounce vial (approx weight 39grams total) - platinum group metals Location of sample from NW Tasmania Halls Open Cut mine dated around 1960. Osmiridium is an alloy of osmium and iridium found in alluvial deposits scattered sparsely around the world and which often contains smaller amounts of other elements mostly from the platinum group metals (PGMs). This material occurs naturally as small, silvery metallic pieces with a hexagonal crystalline structure. Osmium is one of the rarest stable elements in the earth's crust and is also the most dense. Its estimated average concentration in the earth's crust is 0.05 parts per billion. Osmium has unique properties that have applications in the medical and electronics industries. Iridium is also exceedingly rare with as estimated concentration in the earth's crust of 0.001 parts per million. Iridium is the most corrosion resistant metal, is the second most dense and has the second highest modulus of elasticity as well as a very high melting point. Iridium's unique properties have application in the electronics, aerospace, shipping, and chemical industries. This is a very rare alloy composition to come across as very little is mined, the current market price is approx $400 usd per Troy Ounce of perfectly refined osmiridium. These osmiridium crystals are small and of various sizes as per the photo. The powder form of osmium can be dangerous given the high toxicity of its oxidized state, osmium tetroxide. The crystalline form osmiridium that we sell is considered safe. As we suggest with all of our metals, please keep them stored in a safe place, do not ingest them, and keep them away from children.
