Mineral Specimen #1227 Myrickite: Cinnabar in Common Opal
Winnemucca District, Humboldt Co., Nevada, USA
Brilliant red Cinnabar which contrasts nicely with enclosing white opaque Common Opal. Myrickite is an old name used by lapidarists for this material. It does take a high polish and makes quite nice cabs. There are a few small, scattered, isolated dark included spots which may possibly be Metacinnabar.
