Brandburg quartz - amethyst crystal. The amethyst is a lovely deep colour, with more depth in the centre. There is a small bridge crystal near the base of the crystal, where it is still attached to some of its groundmass. There are interesting growth markings on the two main faces of the crystal; and flashes of fire quartz within, making it a highly unusual combination
