Metallic microinclusions of the extremely rare ruthenium-osmium arsenide anduoite from the type locality in Anduo, Tibet, in a specimen that was analyzed. Evidence of the analysis is still present in the specimen since it is a polished section with a thin sheet of copper, usually used to make the sample conductive under the SEM/EDS machine. Associated mineral species are irarsite and rutheniridosmine, which match perfectly with the material from the type locality described in Mindat ("Best of"article"): "The mineral occurs as massive grains or granular aggregates (60 to 100 μ) in a chromium deposit related to augite, peridotite, and dunite…Anduoite and other arsenides and sulfarsenides, often distributed around the grains of rutheniridsosmine, are closely associated with irarsite and show replacement of irarsite". Ex Vandenbroucke Museum collection from Waregem, Belgium. Mineral

Andyrobertsite, Calcioandyrobertsite Locality: Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia (Locality at mindat.org) Size: 3.3 x 2.5 x 1 mm. A piece of the only known specimen of Andyrobertsite and Calcio-andyrobertsite (see the Mineralogical Record, Vol. 30, #3, May-June, 1999). The color on this single crystal ranges from a spectacular royal blue (Andyrobertsite) to a beautiful and intense green (Calcio-andyrobertsite), with a superb luster to match. Both are valid species in a series. This specimen was peeled off the TYPE SPECIMEN and so is a HOLOTYPE. This means that it is a validated piece from the type descriptive specimen listed in the scientific records for the species. It is accompanied by the label from William Pinch, who gave it to Charlie as a gift when Bill found out that he had a new species. Bill bought the specimen (said to have been found about 1950) years ago and to this day it is the only one that has turned up. This is a rare trim he peeled off it, for his friend, with documentation. Mineral
