For sale is this size 10, man's 10k white gold ring set with a nice, clean 0.25 carat solitaire diamond and black onyx. The setting measures almost 5/8" from north to south and weighs a hefty 9 grams. It has a neat stepped design in following with the style of the Art Deco era and not only has onyx in the center, but it has two separate strips of onyx on the shoulders. Please note that the only wear to the ring seen in the last picture is great exaggerated by my extreme close ups and really cannot be seen without a loupe. Diamond is clean with no visible carbon or inclusions.
