10k Yellow Gold Diamond Marquise Shape Cluster Women's Ring, Size 7, Pre-Owned.  Good Condition.  There are 18 or 19 Round Diamonds.  Sorry I do not know TCW as I am not a jeweler.  The diamonds on the side are just for illusion and are not diamonds.  The band is approximately 3 mm.  The ring weighs 5 grams and is stamped 10K, not plated or filled.  Please refer to the several photos that I have posted so you can judge accordingly.  Will include a gift box.  Shipped USPS Ground Advantage.  Thanks for Looking!
