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.

Larger specimen of pinkish red Hureaulite in masses and crystals to 3mm with cavities filled with sugary lime green Tavorite and clusters of well-defined, excellent crystals in groups to 2mm. These are fabulous crystals of Tavorite, some of the best around. At the Tip Top mine, Tavorite is uncommon and crystals are very rare. I'm not sure if there is a better locality. Scattered around the cavaties to a lessor degree are tiny less than 1mm opaque yellow-orange Ushkovite crystals, deep red Bermanite and purple Leucophosphate crystals.

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.
