Glasslike faces with high luster and very sharp edges define this older Mexican Calcite. The crystal is twinned and transparent with fine violet color throughout. The reflective faces makes this hard to show to well in photographs but in person it is striking. The display side of the piece is in fine shape, the bottom and rear are contacted or broken in areas that can be concealed by display angle. otherwise only very tiny edge rubs are found with 10X loupe, this is naked-eye clean and impressive for any Calcite.
