Tom Wood coin ring. - Material: Silver 925 - Design: Coin design - Engraving: 925 - Shape: Round ring Thank you for viewing. The size is size 19. The previous owner had it enlarged from size 18 to 19 at the store where they purchased it. I loved it and thought it was incredibly cool, but it's too big and slips off, so I'm selling it. There are a few scratches, but they're not noticeable due to the design's processing. This is a popular model, so if you're looking for one, please consider it! The following is from the Tom Wood website: The coin ring is a classic signet ring featuring a coin with a slight oxidation finish. This coin is cast from a genuine ancient Greek coin used in Afghanistan thousands of years ago. It is a coin of Alexander the Great of the ancient Greek Kingdom of Macedonia. This ring is made of polished sterling silver 925 and is white rhodium plated to strengthen the surface and prevent discoloration.
