Item Description

A beautiful and aesthetic CABINET amethyst specimen. Gorgeous, glassy, translucent to transparent, blush-purple amethyst crystals, to 5.5 cm, dramatically stand, jackstraw-style on the sculptural quartz matrix. The crystals really sparkle and are called "cactus quartz" for their form. The gemmy 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. The bit of noted periphery wear, reveals the filled-in hollows, where the precipitating silica-rich fluids flowed, adding character. Ex Richard Rossi Collection. Richard is a Senior Fellow of the Mineralogical Record. A lovely example with great color.
