Uneek Petite Oval Blue Sapphire Ring with Diamond Halo and Split Upper ShankThe good thing about sapphires of the royal blue kind is that you do not need a large one in order to make a statement, as demonstrated by this piece; the ring is petite, the shank is simple (splits in the upper portion), the halo is straightforward, but the oval center, despite being a few points short of a carat, makes the whole thing just as imposing as all the other rings in our Royal Blue Collection.
