Large, mounted specimen of red-orange realgar and yellowish orpiment, both arsenic sulfide minerals but with different crystal structures. The paper label on the styrofoam mount indicates it came from Humboldt County, Nevada, without any mine name, however, the Getchell Mine in the Potosi Mining District of Humboldt County, Nevada, 35 miles northeast of Winnemucca, is a well-known collection site. Realgar and orpiment are almost always found together, since realgar (AsS) converts to orpiment (As2S3) when exposed to air. This is a hard-to-find size of specimen of this unusual mineral.
