Spirit Quartz is found in South Africa. It's unusual in that drusy Amethyst grows over an opaque Quartz shaft, thus creating a sparkly, cactus-like specimen. I learned with considerable glee, that this Quartz was not named "Spirit Quartz," because of any isoteric, or transcendental reasons. The African miners named it Spirit Quartz because when they found the good color (a rich purple) they could then get paid and buy some of the readily available "mentholated Spirits," at the local liquor store. Apparently both Spirit Quartz and Mentholated spirits have the same purple color! 

This piece is aesthetic and has crystals that are on average 9 cm (3 1/2 inches) long. It displays well, and is in good condition. Unseen from the displayable angle, on the back there is a patch where some of the drusy Amethyst came off, thus exposing the primary Quartz shaft, probably when it was extracted.
