This is an early Jeff Cooper offering. It is 0.34 CT TW of lush clear blue Sapphires and 0.21 CT TW clear Diamonds on a 18 K gold band.
The ring is size 6.5 and could be sized by your local jeweler if needed. It weighs 3.1 grams and is 3 mm on the front and 2 mm at the very back.
I have sold several of these excellent bands by this NYC designer. A Ruby one which was larger and a multi-stone one which was smaller. They add that wonderful pop of color to a stack of rings. Excellent condition.
