The crystal is very complex with many faces, among which the sharp rhombohedra and shortened scalenohedra stand out, giving it an equant shape. Above all the uniform yellow color, the transparency, brilliance and position on the Dolomite matrix are great. The locality is now completely lost because it is impossible to access it.
