A huge amethyst geode may be just what you need to promote sobriety, piety, celibacy, love, happiness, and good dreams, at least according to popular myths. Amethyst ranks as a seven on the Mohs scale of mineral hardness, with diamonds coming in at the hardest rating of 10. Amethyst is the most valuable type of quartz, and it has a high iron content that gives it the beautiful purple or lavender color. It was a stone of royalty for thousands of years because of the aesthetic appeal of the color. Higher levels of iron make the purple color darker and increase the stones' values. Large amethyst geodes have smaller six-sided individual crystals called druze. Large, clear crystals in regular, organized patterns make geodes more valuable and attractive. Brazilian amethyst geodes formed after millions of years of volcanic activity. Other productive amethyst mines exist in South Korea, Austria, Siberia, and Sri Lanka. Rely on the sellers on eBay to help you find the perfect huge amethyst geode to serve as a gorgeous conversation piece or an elaborate gift.
