sought-after ! Vintage Cocktail Ring

This is a exquisite vintage cocktail ring from the 1990s. The ring is made of 925 Silver with a gold Vermeil finish. The ring is in extremely good condition. I received it, from a late relative in 1999 and have had it packed in my storage since 2000. To me it looks like a style similar to those of The Deco era in the 1920s. Ring is a size 10 and the markings are 925 with an image of a diamond & China. Feel free to ask questions thanksl
