An epitome of shimmer, this ring is adorned with diamonds all over, not to mention the sparkling huge cushion cut lab diamond as the centrepiece. It is mounted securely on a four-clawed structure of an elegant 18K White Gold band, which is embedded with beautiful round diamonds, 12 on each shoulder, creating a magnificent glitter. In addition, the mount is bordered with a row of petite round diamonds on the upper area, on all its sides, and just beneath the solitaire along the length of the claws and the base of the mount on all sides. With the entire mount studded with diamonds and the band exuding a row of sparkle, the ring is a priceless piece of jewellery, all set to create a sensational statement.
