Fashion Ring with Turtle Setting and Black Stone - Size 7 (EUC)

Fashion ring with turtle setting and black stone - excellent condition. Size 7 (as shown on sizer in photos). Undetermined stone - no facets so may not be a stone at all. Ring is not stamped that I could find. Next to no signs of wear or bends in band. Some scratching on ‘stone’ and no facets to see any other flaws. Measurements are approximate. Comes from a smoke free, pet friendly home. All jewelry in my closet is cleaned and disinfected before posting!
