A spectacular, two-sided amethyst specimen. Gorgeous, glassy, translucent to transparent, purple crystals of amethyst to 5.5 cm in size stand upright on the striking matrix of an earlier generation of quartz crystals. The crystals really sparkle and are called "cactus quartz" for their form. The terminations are isolated, while the bodies have a prickly, "cactus" look with an overgrowth of smaller crystals. The yellow iron oxide inclusions are a nice accent. This is the true source for the amethystine quartz crystals (aka "cactus quartz" and "spirit quartz") erroneously marketed as being from the Magaliesberg Range. A super example with great color. The amethyst crystals are all pristine.
