Locality: Moscona Mine, El Pontón de Solís, Corvera de Asturias, Asturias, Spain (See on Mindat)
Size: 4 inches

Description:
Here is a beautiful fluorite with phantoms from the Moscona Mine in Asturias, Spain. Not the typical blue, but instead a very soft cream yellow, though slightly different across the wavelengths. The phantoms, though, appear in all three wavelengths. The non-fluorescent material in the top center apparently is dolomite. Pretty, but no glow. Also, there are some little specs that do glow in LW, a very dull, dark red that are scattered about the piece. It is suggested that they may be cinnabar.
