A large amethyst geode in two halves from Aurangabad. From the outside the geode is unremarkable, but split open, both halves show a cavity fully lined with sparkling purple amethyst crystals.

The edges reveal a layer of white, translucent quartz beneath the purple, which frames the color well. Amethyst geodes form when silica-rich fluids fill gas cavities in the Deccan basalt lava flows, and the purple color comes from traces of iron combined with natural irradiation. Aurangabad district is one of India's steadier sources of well-colored geodes.

At over 10 lb, it is a heavy, impressive pair for display.
