Faceted amethyst pendant & gracefully twisting chain, both sterling

Very lovely pieces. The pendant, about an inch long with the bail, includes two stones, a dark purple oval above a lilac raindrop. The chain of 17-1/2 inches has a subtle but interesting twist along its length. Both pieces are stamped 925. The pendant is additionally stamped Thailand and SU, while the chain is stamped Italy. Everything is in great shape.
