Silver wave design ring. It may be a design from the 1970s to 1980s. I'm not an expert on rings, but it has a substantial feel. I think it's a wonderful piece. The inner diameter is about 18mm. I think it's a ring that women can also wear. As a bonus, I will also include a pure silver accessory. Not only gold, but also silver is currently rising in price. Offered at a bargain price. Due to the nature of the product, no returns or exchanges. Thank you. - Material: Silver - Design: Wave design
