A plate of medium purple Amethyst as matrix and as a dense coverage of lustrous, stubby, sharp little crystals from a few millimeters to 1cm in length is dotted with rosettes of translucent, snow-white Calcite that average 8mm in diameter resulting in charming little display piece. Ex. Kay Robertson collection with label. Old classic!
