This is a synthetic blue sapphire surrounded by white stones. The white stones may be old synthetic white sapphire stones (they do test as some kind of stone they are not glass).
These rings were very popular in the 40s and 50s. Ring is marked 750 and tests as 18K. Very nice condition. Size 7. Weight 4.6 grams.
