A 2mm deep reddish brown crystal embedded in Sanbornite-Quartz matrix. I am not sure about the identity, thus no return. It seems different than Titantaramellite in both color and shape but may be Titantaramellite. It is an old Carlton Davis specimen.

Mercury has not been mined in the USA since 1992 when the McDermitt mine in Nevada closed. It is now only produced as a by-product from gold-silver mines. Nonetheless, the USA is the leading exporter of mercury since it is still produced through secondary recovery programs and recycling. A 76 pound mercury "flask" averaged $550-650 in 2008 (USGS). At one time the USA had many mines namely in California. Terlingua, Texas had producing mercury mines. Terlinguaite, like this specimen, was a chief ore at Terlingua. This is an old Carleton Davis specimen with tag.
