Trendy 925 Sterling Silver Ring For Men Jewelry Black Rectangle Retro Dragon Pattern Ring Male Infex Finger Accessories Open

The ring does not match the quality described. There is no 925 hallmark, and there are stains/spots on the metal. Instead of a stone, it looks like it has simply been painted. The ring looks like cheap costume jewellery. I do not believe this is genuine 925 sterling silver. How can I return the item and get a refund?
