This Art Deco era cocktail ring features a 5.86 carat shield cut iolite set in platinum with decorative filigree mounting and bezel setting for the center stone. Twenty old European cut diamonds are set across the face, adding 1.04 total carat weight to the design. The shield cut iolite displays deep purple-blue tones that contrast beautifully with the white diamonds and platinum. This ring captures the geometric design elements and bold proportions that defined jewelry from the Art Deco period.
