A unique and highly unsual quartz specimen from the much less well-known Four Peaks Amethyst Mine of Maricopa County, Arizona and the Richard Hauck Collection. This strange-looking quartz is a doubly terminated amethyst/smoky quartz crystal. The crystal looks octahedral and has fabulous etching. The narrow, smoky termination is water-clear. The photo highlights the crystal translucency, highly variable purple/smoky color saturations and the incredible etching. Very nearly pristine.
