Masculine Sterling Silver Gear Machinist Rayures ring retail size 11

Product Name: Masculine Sterling Silver Gear Machinist Rayures ring retail size 11
Pre-owned menʻs ring in sterling silver (has a 925 hallmark on the inside but no makerʻs mark) shaped like a gear or machine cog. Raised retail gear "teeth" and the lower areas are black. I used a microfiber cloth to clean it up but no buffing or polishing. Ring as pictured, it is used with minor surface scratches and small ding here or there but nothing major. Some light scratches on the inside of the ring (where it touches the skin, but can't be seen when worn. Could be readily resized as the back of the ring is flat (that past that is exposed in the palm) so jeweler has space to work.
