Beautiful translucent to transparent smoky Quartz crystal, contrasted by a matrix of white Feldspar visible on either side of the crystal. Very well formed with sharp stepped termination, glassy lustre and fine internal phantoms. A fine sparkling layer of yellow Gilbertite Mica coats the side of the Quartz and the Feldspar. A genuine rarity for this country, slight chips to termination and one side.
