※ This is a one-of-a-kind ring. Please confirm availability via comment before purchasing! Thank you for viewing this item from among our many products! We are pleased to present a ring featuring a 4.01ct Sri Lankan blue sapphire with a royal blue color, certified by the GRC, a gemological institution overseas. Despite its deep, rich, and powerful color, it is rare to find a sapphire with such brilliance, luster, and exceptional transparency. Furthermore, the motif part of this ring can be detached, allowing it to be used as a pendant top. (See photos 7 and 8; chain not included) Round brilliant and marquise diamonds are used for the surrounding diamonds, making the normal surrounding design more decorative. The European atmosphere further enhances the nobility of the sapphire. It is a truly artistic piece, beautiful even when viewed from the back. It will be delivered in a jewelry box.
