Realgar with Orpiment (rare locality specimen)

Item Description

Here we have a rarely seen specimen from the White Caps Mine in Nevada featuring stark vibrant red Realgar associated with goldenrod colored Orpiment. I can't say for certain when the specimen was collected, but the entry on mindat.org for this locality states that a fire within the mine in 1958 "put and end to the mine's production life", so this piece is certainly close to 70 years old, if not much older. Very hard to find on the market, and certainly with such a good visible mixture of both species.
From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974.
