This is a silver ring from M•A•R•S featuring a natural onyx stone in the center with sheep designs on either side. The inner diameter is 19mm. I purchased this a while ago, but I rarely wore it and mostly kept it for display, so there is no visible damage. It comes with a dedicated pouch. - Brand: M•A•R•S - Materials: Onyx, Silver - Size: Inner diameter 19mm - Accessories: Dedicated pouch Thank you for looking.
