Large statement silver ring. With many security prong set amethyst stones of light purple/ lilac / lavender color. Size 8.5. Stamped 925 and has a makers mark OTAZU. Has a bit of wear on the inside of the band, otherwise in very good condition. Judjung by the look and the feel of the metal, not sure if it is made of real sterling silver though. Selling as is and pricing as a good quality costume jewelry with natural stones.
