Idrialite, Cinnabar and Pecoraite with accessory minerals from the Culver Baer Mine, California – 1 unique flat

This remarkable selection from the Culver Baer Mine in Sonoma County, California, features a striking combination of rare and unusual minerals. The pieces show vivid red patches of Cinnabar, yellow-green areas of Pecoraite, and dark blackish-brown zones of organic Idrialite. Under UV light, the Idrialite exhibits a bright yellow fluorescence, making this flat highly attractive for fluorescence collectors as well. The specimens are mostly compact, with massive character; some show layered structures or shiny zones, indicating finely distributed crystalline components.

Geology & origin

The Culver Baer Mine is a well-known source of mercury-related secondary minerals in California. Idrialite – a rare hydrocarbon mineral – typically forms in such geologically active mercury deposits, where hydrothermal activity mobilizes and deposits organic compounds. Cinnabar is the main mercury-bearing mineral, while Pecoraite appears as a nickel-bearing secondary phase. This rare mineral combination from a single locality is only documented at a few places worldwide. The flat shown is exactly the one offered.
