These specimens are primarily botryoidal clusters of orpiment on a minor amount of matrix with or without barite and/or realgar. The orpiment is very delicate and the surface easily "bruised", the lighter colored area on many of the specimens. Most of these specimens are miniature to small cabinet sized.
The Quiruvilca Districts is a lead/zinc/copper/silver deposit and is particularly noted for its fine enargite and pyrite specimens.
