10k Gold with a deep purple stone, this is a smaller ring, 4.5, which I used to wear on my pinkie. It's stunning with prongs on either side to form a twisted setting and years of wear on the gold shank - it has hardly been worn at all. The prongs are in perfect condition. The stone is vibrant, similar to an amethyst but perhaps Almandine? The stone stands high, about 5/16 inch. Just a beautiful ring.
