A beautiful two-sided, mounded amethyst specimen. Glassy, translucent to transparent, purple "spires" of amethyst to 6.6 cm in size stand upright on the matrix. 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. This is the true source for the amethystine quartz crystals (aka "cactus quartz" and "spirit quartz") erroneously marketed as being from the Magaliesberg Range.
