Filigree diamond engagement ring Art Deco.  This original antique Art Deco diamond solitaire ring features a brilliant 1.41 carat old European cut diamond.  The diamond is bead set into a decorative square bezel with a milgrain detail.  There is an additional exterior square bezel surround the center diamond creating a slightly larger appearance.  The shank and gallery of the ring have an incredible fine open platinum filigree detail in a scrolling pattern.  The lines of the ring are bold while the mounting feels delicate in structure and is truly a tribute to the capabilities of platinum.
