Like delicate butterfly wings, this Art Deco antique filigree engagement ring flutters around the finger. The domed platinum mounting of this antique ring is delightful with its pierced filigree. A collection of eighteen old style single cut and round full cut diamonds, along with a quartet of rectangular French and mixed faceted cut blue sapphires, accentuates the filigree. Rising out of the center of the dome is a round brilliant cut diamond. Weighing 1.12 carats, this GIA certified center diamond is I in color and SI2 in clarity. The total diamond weight of this Art Deco engagement ring is 1.365 carats. From the Topazery Tara Collection. Circa 1920s.
