Vintage Edwardian meets Art Deco 925 sterling silver pink stone ring 7.75

Vtg antique Edwardian meets Art Deco 925 sterling silver & pink stone ring 7.75. Gorgeous ring with a style that’s a little Edwardian and a little Art Deco. The setting almost resembles a frame, set with older marcasite stones and surrounding a baguette cut pink stone (my guess is topaz?). The stone could also be glass. It’s well cut and open on the back to allow lots of light to shine through. Stamped 925 on inside band. Sits at a 7.75 on my ring sizer. Good condition. Light wear. One marcasite stone is missing from one corner, and another is slightly damaged. Silver has aging/oxidation/discoloration. Band seems a little wonky. Stone could benefit from a careful cleaning. Please refer to photos for additional condition details. 4D
