A superb cabinet sized Orpiment with perfect, gem-clear transparent crystals in a complex cluster perched on a white Calcite matrix. Many consider this sort of Orpiment from Shimen to be the best ever found in the world, it is certainly world class when of this quality. Excellent color intensity (better in person) bright glassy luster and with some chantoyance seen in a some prisms. An older specimen from Shimen (2005) this has not been acid dipped or shows any signs of crumbling, or alteration. Specimens were sometimes enhanced in acid baths but this tended to cause degeneration over time. This is fully natural, undamaged, and with a lot of display impact. The crystals are free standing terminated with pyramidal tips and reach over 2.2 CM. Hard to render well in photos due to the many internal reflections and bright luster. Outstanding and no longer available, the mine closed a few years ago.
