Wow, 28 carats of pure, ethical gemstones in this handcrafted show-stopper of a ring. With a 22 x 16mm central green amethyst and 2 purple amethysts either side, this outstanding trilogy piece in Sterling silver has a beautiful presence which is enhanced by the properties of the stones. To be worn at all times - daytime and nighttime. We recommend a snug fit for this large ring.
