What an exquisite solitaire ring this is; a round diamond set in a square mount.  The diamond is set with four claws within a millegrain border.  The mount is open allowing the light to filter through the diamond  unhindered and has a faintly Art Deco style.  Scroll design, tapering white shoulders each set with three diamonds are a further adornment to the setting which is on a D shaped yellow band.  Stamped 18ct plat and testing as 18ct gold and platinum.
