Lighter areas of the matrix create an attractive contrast and enhance the lively structure of the specimen.
The Descloizite crystals are clearly visible and abundant. They display a strong luster and form a uniform, dense crystallization that gives the piece a particularly appealing and high quality appearance. The crystals are well developed and contribute significantly to the aesthetic character of this collectible specimen.
Geology & Origin
Descloizite is a vanadate mineral belonging to the adelite descloizite group and forms in oxidized zones of vanadium rich deposits. It typically occurs as a secondary mineral in arid environments and is often associated with other vanadium minerals.
The Grey Horse Mine in Arizona is a well known locality for high quality vanadium minerals and has produced numerous aesthetically appealing Descloizite specimens. Pieces from this locality are highly valued by collectors for their intense colors and dense crystallization.
