Orpiment is another arsenic sulfide mineral with a stunning orangeyellow color. The mineral is found naturally in hydrothermal vents, hot springs, and fumaroles. Strangely, this mineral was once used medicinally in China despite its toxicity and in alchemy in search for a way to create gold.
Realgar pigments. Orpiment has a first cousin, realgar, also sulphide of arsenic, which is beatiful an orange as or orpiment is a yellow, an bright orangered mineral composed of arsenic disulfide. Realgar occurs naturally in lead and silver ores along with orpiment (arsenic trisulfide).

Orpiment is a rare mineral that usually forms with realgar. In fact the two minerals are almost always together. Crystals of orpiment are extremely rare as it usually forms masses and crusts. The masses are sometimes transparent to a degree and have a gemmy quality to them.
francis Quartz With Realgar, Orpiment and Sphalerite From The Paloma Mine, Peru.
A specimen of elongated orpiment crystals from Shimen. These are usually heavily damaged and somewhat mistreated (orpiment is particularly susceptible to showing scuff marks), but this piece is in remarkably good condition, all things considered.
Orpiment and Calcite stock #Alec15207 Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture Hunan Province, China 8 x x CM (cabinet) price: 380 pre Tucson 2015 update Sharp white Calcite scalenohedrons make a wonderful contrast to the orange red crystals of Orpiment. The Orpiment is sharp and well terminated with translucent to gemmy area.
The Getchell Gold Mine is located on the east flank of the Osgood Mountain Range in the Potosi Mining District, Humboldt County, NV. It has produced the very finest orpiment and realgar specimens in the USA. Mining in the area first began in 1883 for copper, lead and silver in skarnrelated deposits.
both realgar and orpiment have been reported previously, the products of this oxidation in a natural environment have not been fully characterized. This study focuses on the behavior of As in the weathered tailings of the Shimen realgar mine, the largest carbonatehosted realgar mine in .
Orpiment. Orpiment, the transparent yellow mineral arsenic sulfide (As 2S3 ), formed as a hotsprings deposit, an alteration product (especially from realgar), or as a lowtemperature product in hydrothermal veins. It is found in Copalnic, Romania; AndreasBerg, Ger.; Valais, Switz.; and Çölemerik, Tur.

Yellow Colorants. Due to its toxic nature, it is not surprising the Romans used slave labor to mine it from the earth" (Ball, 100). In modern times, orpiment is still mined in the United States, though its popularity has decreased considerably since the invention of other, less toxic yellows.
Brief description of Orpiment: It's an arsenic sulfide which naturally occurs widely, but in relatively small deposits. In modern times the artificial version can be made through a process of sublimation and precipitation. Known to the Greeks as arsenikon and related to the Persian zarnikh which is based on the word zar, the Persian for gold,...
Arsenopyrite (FeAsS), orpiment (As2S3), and realgar (AsS/As4S4) are the most common arsenic sulfide minerals, occurring primarily in hydrothermal and magmatic ore deposits. Arsenic is commonly found in sulfidebearing mineral deposits; especially with gold mineralization.
At Getchell, getchellite cleavage planes over 5mm are unusually large and rare, as well. Getchellite is a very interesting and unusual mineral species. First found at the South Pit of the Getchell mine and named back in 1965, This cherryred, micacious mineral best resembles orpiment in crystal habit.
Orpiment is a mineral of arsenic sulfide with a deep yelloworange color, occurring in hydrothermal veins of low temperature, volcanic fumaroles, and in hot springs as well. Its formation occurs from the decay of Realgar, another mineral belonging to the arsenic group or by sublimation.
