Beautiful specimen of vivid red, flattened, tabular hexagonal crystals of Vanadinite attractively set on a base covered by black Mottramite or Manganese Oxides. The crystals have intense red color with some orange nuances and good luster to more matt. Very sparkling micro black crystals of Mottramite or Manganese Oxides add nice contrast. For references the issue of The Mineralogical Record - Vol. 44, No. 3 May - June 2013. Some damages.

Wonderful!
