| Iridium var. Rutheniridosmine, native Ir,Os,Ru (stable) alloy | (Ir,Os,Ru) | /Images/picture.jpg | Nizhni Tagil, Ural Mountains, Sverdlovsk Oblast, Russia | collected around 1900, acquired 2006 | Matrix | Secondary Mineral(s) | From the collection of John Betts, #33570: Description: "About 40 small metallic flakes of silver-white iridium, a very rare mineral, mounted in plastic display for protection.
Tested by Excalibur Mineral Co. in 2002. Ex. John A. Rorer, Jr. collection #017; Ex. Prof. G.P.Carlson (Univ. of London, 1952);
Ex. E. Noske Collection (Hamburg, 1902).
Overall size of mineral specimen : .2-.8 mm.
Size of individual crystals : .".
The analysis by Excalibur reports Ir 42.73% by Wt for Ir, 41.53 Os, and 15.74% Ru. Rorer's analysis was labeled Specimen IMK#1 - Silvery flakes and reported back a (Ir,Os,Rh) phase now considered as Ruthenosmiridium. A handwritten comment corrects the Rh to Ru (it was correct in the analysis details), and replaces Ruthenosmiridium with Iridium. Handwritten label on the analysis identifies specimen "Iridium 17". The personal notes go on to add "Dana: 1.2.1.2, Iridium, Ir, specimen, when collected in 1900+-, was labeled by Foote 'Iridosmine (var. Siserskite -- flat siz sided scales)', however, var. Nevyanskite is corect since more than 40% iridium is present (42.73% for Iridium, 41.53 Osmium). Now after qualatative chemistry tests it appears that Ruthenosmiridium is the correct identification of this specimen. However, the IMA now considers this to be Iridium since Ir is doominant in this specimen." Under the technical analysis there is a handwritten comment "Rutheniridosmine: 'Ir' is the dominant element. Ir,Os,Ru (hexagonal) [42.73% in this vs 41.53% Os], Dana 1.2.2.3". Some of the small flakes have fallen off the top and are around the upper edge of the case. One os these flakes is a perfect hexagon on five of the six faces (and almost perfect on the last face). |

The 'sand' sample is really used plastic sand blasting pellets.

The process often produces hazardous waste, and self contained breathing protection is needed to avoid problems from the dust. Pellets are generally reused several times before going to the recycler; the pellets start out with sharp edges, and some have abrasive coatings. | 2310 | Hardness | Streak | Specific Gravity | Crystal Form(s) |
