Uruguayan amethyst is the rarest and most expensive in the world, renowned for its being transparent and pure purple with a deep saturation and tone and desirable red flashes. Because the Uruguayan amethyst deposits are nearing depletion, it has become increasingly precious for its rarity, becoming essential items in high-end jewelry stores around the world.
