This is a diamond band set in 14K solid yellow gold. It features 10 diamonds that are 2.2 mm rounds. They total approximately 0.5 carats. They are eye-clean with minimal inclusions visible under magnification. It is a size 5.75, but should be sizeable by a jeweler. Lots of gold in this piece with a band width of 2.9 mm at the narrowest point and it weighs 3.6 grams. Great for stacking or adding to an existing ring. Also, substantial enough to be worn alone. In excellent condition!
