Description

I know of only a few pieces of this bizarre material!This is a reverse scepter of a calcite scalenohedron on which small gem gypsum crystals grow in areas!The piece seems to have recrystallized areas that used to be contacts to other crystals.The color is ochre yellow and the luster is fine on all faces!The sceptered tip makes it a winner and it's in great condition, almost totally perfect!
