A very attractive Art Deco era Tiffany & Co diamond ring built around an exceptionally high quality 0.82 carat old European cut diamond. It's set in an octagonal platinum top, over a wide tapering 18K yellow gold shank. Likely designed as a men's ring but perfectly suitable for a man or woman. Dates to the 1920-40s. Comes with a GIA certificate for the diamond stating F color and VS2 clarity.
