SC1115 – Cinnabar and Idrialite from the Culver-Baer Mine, California, USA

Oct 12, 2024 | Idrialite, Mineral Collection

A very rich piece of yellow idrialite and red cinnabar. Some nice little crystals are visible with a druzy quartz (?) coating. The idrialite fluoresces very bright green under any UV light. The fluorescence photo was taken with a little bit of daylight too. Not sure yet if it is a better daylight or fluorescence specimen!
