I love these old rings. They came in so many colors, and this one has bright red glass. The band is hallmarked 14K and it is white gold. There is lovely filigree work all around the stone and part way down the shoulders. The top of the ring measures approx. 1/2" X 3/8". The ring is a bit over size 5 1/2. Weight is 2.7grms. Pretty flowers on each side, the filigree work looks great for age. Four large prongs hold the red glass well. I would date this fine ring at c1920's.
