This is a vintage 10K yellow gold Ostby & Barton signed ring. The ring is set with brilliant blue, faceted glass stones. The ring face measures 16mm long x 13mm wide. Under magnification, I can see a culet/pavilion chip in the center stone. The band is sized at 6 1/4. Total weight is 1.7dwt/2.7grams.
This is a vintage, previously owned ring. Therefore, light wear can be expected.
