VTG Blue - White Topaz Sterling Cocktail Ring- 10

Incredible Vintage Blue Topaz Ring set in Gold and Sterling Sterling Silvet- Size 10. Large center stone, surrounded by prong set white, diamond-like Topaz stones. The top of the ring is gold (still searching for a Hallmark), and the bottom is made of marked 925 Sterling Silver. Extremely beautiful, and very old. I'm probably setting the price too low, but I don't have time to get to the jeweler today. In excellent condition!
