1920's 14k White Gold Filigree Diamond Ring

For sale is this really cute, circa 1920's, 14k white gold ring set with a small, but genuine diamond. The setting measures almost 5/16" from north to south and is currently a size 5 1/2 (shank is not thick, but it is not weak either). The setting has four tiny hearts around the edges and a lot of fretwork, but one tiny piece is missing (see 4th last picture), not noticeable, but needs mentioning for the sake of accuracy. The ring weighs 1.4 grams.
