Brilliant luster on transparent crystals of Orpiment that are free standing on white Calcite. Top quality for the mineral and for this world class locale, this is damage free and far better in person. Some crystals have an internal chantoyant zone while other are simply transparent. No discoloration or crumbling, this is an older piece that has not been treated with acids or enhanced, it is from 2005 vintage mining. The Shimen mine has been closed for a while and no more specimens are coming. These have been considered to be the worlds best of the specie and are unique in the mineral world. This example is far beyond average, top quality with sharply terminated crystals just over 2 CM tall.
