Vintage Art Nouveau Ring Pearl Sterling Silver Arts & Crafts Blue Floral 8.25

Vintage Art Nouveau Ring Pearl Sterling Silver Arts & Crafts Blue Stone Floral Size 8.25 Vintage condition with general wear, patina, and tarnish. This has some sort of wax or something on the underside, I'm assuming it's part of the construction. Please take a look at all the photos and use them as part of the description. Approx ring size 8.25 No hallmarks but tests as silver I am unsure what the blue stone is, but it is a genuine stone. Very unusual and beautiful piece of history.
