Art Deco Antique Filigree Old Euro Cut .025ct Diamond 18k White Gold Ring 5.25

Another one of my husband's grandmothers rings - she had several diamond rings and I’m listing them all. She was born in 1924. This size 5.25 filigree ring is stunning and such a statement piece! I know they are super old - I’m guessing she inherited it as the research I’ve done shows Circa 1920/1930 - Art Deco Period. The top of this antique ring consists of a triple-tiered hexagon. Tucked in the midst of this three-dimensional geometry is an old European cut diamond. Floral and filigree design mounting. One old European cut diamond is bead set in a hexagonal top plate. I had my local goldsmith / jeweler clean and grade. Below are his comments: 18k white gold - .025 c 2.2 g I2 Will be shipped in protective case!
