Exceptional Art Deco No-Heat Burma Ruby, Platinum and Diamond Ring. A luscious, electric candy apple-red, square emerald-cut ruby, accompanied by an GIA certificate stating: no-heat – Burma origin, radiates from within a superb and stunning platinum and diamond ring – circa 1930. The gemmy 2.12 carat gemstone is embellished east and west with a sparkling champagne glass motif composed of a half-moon diamond and a pair of slender straight baguette diamonds; the north and south side shimmer with a small cascade of channel-set baguette diamonds, all of which are outlined with small round diamonds. Supreme!
