Montroydite (rare mercury oxide - Type Locality) Edgar Bailey Coll.

Item Description

A very rich and unusually large specimen of the super rare species montroydite, a rare Terlingua mercury mineral. From the Type Locality and an important collection, the remainder of which is now in a museum. The piece has a thick mineralized vein running through it, and is rich with dark red microcrystals on attractive contrasting calcite. The dark red is the montroydite, and the orange mineral is kleinite. Edgar Bailey was a noted mineralogist and field collector of Terlingua minerals, and the species Edgarbaileyite is named after him in honor of his work. This is from his collection and was self-collected by him, part of a suite of such pieces. His label has a March 5th, 1945 date. Light orange fluorescence on the calcite is also present. Hard to value, but a VERY rare piece of a very rare species from a pedigreed source
