Classic ring in deep purple, made of silver. - Stone color: Purple - Material: Silver, with markings - Design: Classic style - Accessories: Jewelry case This ring was found in a traditional Japanese chest of drawers at my parents' house. Inner diameter: Approximately 16mm I searched using AI and it indicated onyx, but as there are no details, I am sorry but I do not know the exact type of gemstone. It has been stored for a long time, and I am unsure whether it was purchased or received as a gift, so please understand. ❉Price reduced again. Please consider purchasing.❉ Thank you for viewing.
