This is a silver ring. It shines beautifully and makes your fingertips look fashionable! It likely has an amethyst, but I'm unsure of the exact stone type. Size: 10 (Japanese size) There is a silver hallmark. I took photos, but it was too small to capture clearly. This is a used item. It appears to be clean with no noticeable stains or scratches, but please understand this before purchasing. The case is not included. Thank you for looking.
