Vintage Dragon's Breath Art Glass Ring in Sterling Silver Size 6

Vintage sterling silver ring with a floral daisy design. It is set with a dragon's breath art glass stone. The surface of the stone has scratched and an indentation that is not a chip but happened when the stone was made. Has many internal bubbles. It is a size 6. the shank is split in the back making it adjustable. However, I looked at the split which is very straight. It looks like it was sized at one time and the solder joint did not hold. Face measures 3/4" long. Weight" 3.4 grams. Marked sterling.
