These are amethyst geode bookends, made from volcanic rock cavities lined with purple quartz crystals. Amethyst is a violet variety of the mineral quartz, with colors ranging from light mauve to deep purple. The color is caused by natural irradiation of iron impurities within the crystals. Geodes like these are formed over millions of years as mineral-rich water deposits silica and iron oxide into volcanic cavities, allowing crystals to grow. Major sources for amethyst geodes include Brazil and Uruguay. (Google AI)
