1.67ct GIA Certified Color Change Alexandrite, 0.40ctw SI1-SI2 White & Yellow Diamond Solid 18K White/Yellow Gold Ring (Comes W/$14,500 Appraisal) - This lovely ring was finely crafted of solid 18k white and yellow gold, and is decorated with a 1.67ct GIA certified cushion cut color change alexandrite. Alexandrite is an extremely rare gemstone with pleochroic (color-changing) properties when viewed from different directions, and the most beautiful alexandrites also change color from daylight or fluorescent light to incandescent light due to its unusual light-absorbing properties. This beautiful gemstone is "Green changing to Purple" according to the GIA report, one of the most sought after colors you can find. The ring is then finished with approx. 0.15ctw yellow diamonds surrounding the alexandrite and 0.25ctw fiery white diamonds lining the perimeter and shoulders of the piece. The ring shows wonderful attention to detail, as the yellow diamonds are set in yellow gold to best display their radiant color. The head of the ring measures 10.5mm x 10.5mm and the band measures 1.3mm wide. The ring will be accompanied by the GIA report for the alexandrite, along with a $14,500 insurance valuation report in the winning bidder's name by a graduate appraiser. Ring size: 7.
