An exceptional 5.29-carat cushion-cut ruby is the star of this showstopper ring. The gemstone displays a highly desirable vivid red hue, commonly called pigeon's blood red for its vibrancy, saturation and lack of fluorescence. The stone is certified by the GemResearch Swisslab as being Mozambique in origin and a "GRS-type pigeon's blood ruby." Diamonds totaling 1.09 carats join the ruby in its classic platinum setting.
