2.3" Cactus Quartz (Amethyst) Cluster - South Africa
This is a beautiful, light purple, 2.3" wide by 2.9" tall cluster of cactus/spirit quartz (amethyst) from the Magaliesberg Mountains, South Africa. The base of this cluster has been left flat to allow it to be displayed without the use of a stand.
Cactus quartz, often also referred to as spirit quartz, is a variety of quartz characterized by second-generation druzy crystals growing on the faces of larger quartz crystals. The small second-generation crystals point away from the prism and their orientation is not related to the crystallographic orientation of the central crystal. Cactus quartz is currently only known from the Magaliesberg Mountains region of South Africa, and comes in a variety of shades ranging from white to deep purple to orange colorations. The deep purple amethyst points are the rarest and most coveted by collectors.
