This gorgeous solid 18 kt white gold ring contains 22 4.5 point European-cut round diamonds totaling about 1 ct. Total Ring Weight is 2.50 grams. Band width is 3.2 mm and ring size is a U.S. size 6. This ring was made in the 1920s or 30s - art deco era. Each stone is set in its own frame - truly a stunning setting and gorgeous ring. With a loupe, I can see that one diamond is larger than the others ... only by half a point or so. It may be a diamond that was replaced a long time ago. The diamonds, which sparkle with amazing fire - seem to be a very nice color and clarity. The ring is not marked anywhere, but is guaranteed as described. In excellent condition.
