Crafted in 18 karat yellow gold and platinum, this Tiffany & Co. solitaire ring is from the Retro period (1940's) and features a 1.39 carat old European cut diamond as its centerpiece. This GIA-certified diamond boasts a VS1 clarity and H color and has exceptional brilliance. The diamond is securely held in place by a six-prong platinum basket mounting that blends seamlessly with the center stone.  The polished yellow gold band adds a warm and elegant contrast of color to this antique Tiffany and Company piece.  As classic as it gets, this vintage piece is a showstopper!
