This is a very unique sterling silver and amethyst ring. It is marked 925 and C A on the inside of the band. The amethyst is cut so that it molds to the shape of the ring. It has horizontal facets on the face. I believe this is called a buff top cabochon cut. The ring is a size 10. It is in very good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
