The vibrant purple hue of amethyst has made it a favorite with royalty, its lush translucence radiating from the thrones of kings & queens throughout history. Amethyst has been said to improve the wearer's knowledge, mood and intelligence. In Ancient Greece, amethyst was believed to be a deterrent against drunkenness, leading to the production of goblets crafted entirely of the regal purple gemstone. Amethyst is also the 6th wedding anniversary gemstone and the official state stone of Georgia.
