LeVian 18K Diamond Sapphire Vintage Gold Ring

Beautiful vintage 18k white gold ring with diamonds and a sapphire. This is a dainty ring and my photos are greatly magnified. The sapphire is a nice blue the photos were taken outside so indoors it appears darker but still you can see it’s blue. I don’t know the diamond weight or sapphire weight. I’m guessing and that the weight of the sapphire is at least 1/2 a carat and same with diamonds could be more. Little scratches from age and wear nothing major. Can use cleaning.
