Vintage sterling silver Art Nouveau style ring. It has A floral theme with decoration that goes all the way around the band. Face measures almost 1" long. Marked sterling inside. Because of the shape of the ring, I cannot get a good sizing from the mandrel. The stone touches your finger as you wear it. The approximate size is 6 1/2. Weight 5.8 grams. 

Bright blue stone is faceted glass. It has many small edge chips .
