VD59Y3: Group of crystals on matrix, with a very well marked barrel-shape and vivid orange color with the intense luster typical of this type of sample from the Bunker Hill Mine. As a rarity, we note a coating of a second generation of yellow crystals with a prismatic shape and very well marked curvatures of faces and edges. While this type of crystals is described as arsenical, nor by the bibliography or by analysis we have done previously, we know that this is so.

Orpiment

This was the main novelty from Tucson 2000. These were found in April 99 at the Twin Creeks mine, north of Winnemucca, Humboldt County, Nevada. Many specimens were found, but the majority of them were pale orange or yellow. The Orpiment was found in the 62 bench of the mine and the geologists seeing them decided to preserve them so they were removed manually with great care.
Orpiment is a stable mineral that does not alter over time, however like many other minerals it is sensitive to sun light so it is best to display specimens in darker areas of your display.
