This set of two elegant amethyst stackable rings spotlights amethyst, the February birth stone, accented by lovely white diamonds in our exquisite stackable eternity ring platinum settings. A stackable rings set is both chic and classic! In ancient times, the amethyst was said to hold many mystical powers. Though most of these legends have passed, the birth stone stackable band can now communicate other things; not only one's own birthstone, many mothers, for example, have put on sets of individual rings with gems for the birth month of each of her children.
