Adamite (classic material)

Item Description

Adamite is a well-known zinc arsenate species, but were it not for the stellar specimens from the Ojuela Mine in Mexico, it would not be nearly as recognized by collectors. I think it's safe to say that the finest examples ever found are those from this renowned locality. These pieces are incredibly beautiful for their excellent color and crystallization. This particular specimen features excellent radial groups and individual "wedge"-shaped crystals of fine quality, lustrous, light yellow-green Adamite with smaller virtually colorless micro crystals of Adamite on Limonite matrix. The largest radial group of Adamite measures 1.2 cm across. The piece shows an intense green fluorescence under SW UV light. A good cabinet sized piece of this classic material with no major damage that I can find.

He worked briefly as a drill runner at the famous Sterling Mine, in Ogdensburg, New Jersey and from 1987 to 1990 he helped convert the mine into a public access mining museum.
