VARISCITE

 

Variscite is a hydrous aluminum phosphate mineral (Al(PO4)2H2O).  It has a bluish-green color similar to turquoise, but is much scarcer.

 

Variscite (blue-green) in polished nodule from the Clay Canyon Mine, Utah County, Utah, USA.  The dirty yellow-green portions are the rare phosphate mineral crandallite (CaAl3(PO4)(PO3OH)(OH)6).
