Vintage Cobalt Glass Vase Blue Glass Silver Toned Insert Tall Ornate Large

Up for auction is this vintage vase. It has a metal silver tone holder with a cobalt blue glass insert. It is 8 3/4 inches tall and 5 7/8 inches wide at opening. I see no chips or cracks in the glass. The silver has wonderful ornate detail. I tried to find a makers mark. I could only find an etched marked on the bottom of the silver - it looks like a backwards 3 then a 3/8/2. The previous owner said that it once belonged to her mother-in -law.
