This six prong rose and platinum Tiffany style solitaire engagement ring contains the following. The center stone is a GIA certified round brilliant cut, which weighs 2.20 carats and has a color and clarity of I-SI-2. The diamond is a triple "X" stone meaning it is a perfect stone. The diamond has a excellent cut, symmetry, and polish. The center diamond has not fluorescence and the SI-2 is not black and is a white feather off to the side of the table and not seen with a naked eye. This stone is a steal and mostly because of the purchase price we bought it at. The center diamond sits atop a 14k rose gold diamond ring which has .50 carats of round brilliant diamonds that exhibit a color and clarity of G-H SI. The ring is cast from 18k rose gold and platinum. This ring is a perfect engagement ring for anyone looking for a timeless ring design.
