The 'Illusion Setting', popular in the Late Art Deco era through the early 1950's, gives the stone the illusion of being square, with the sparkle of a brilliant cut! It also protects the stone, and gives it a pretty feminine effect. This center stone is lovely, with good color and a great bright clarity! Set into pretty, decorative, yet also protective white gold prongs, the diamond is nicely accented with a beautifully proportioned milgrain edged shank, with pretty little sparkling pave set diamonds on each shoulder! A true vintage classic!
