10K Yellow Gold Sapphire Cluster Ring Size 5 3/4. This ring is classically beautiful and features 3 marquise cut blue sapphires that are approximately 0.08 carats each, approximately 0.24ctw or just under 1/4 carat of sapphires. There are also 2 small white color accent stones, but they are small enough that my tester can’t not touch the surrounding gold setting and therefore I can’t determine what they are. The ring is in good shape with just some minor scratches on the band. It is a size 5 3/4 and weighs 1.5 grams.
