Uneek Oval Tanzanite Halo Engagement Ring with Ribbon-Style Crisscross Upper ShankWe borrowed one of the more popular engagement ring styles from our Radiance Collection and put a 3 carat oval tanzanite on it, and the result is just breathtaking; there's 80 round brilliant cut diamonds U pave set along the halo and down the very delicate looking crisscross style double shank; what makes this style more eye catching is the openwork design in the gallery; from Uneek's Royal Blue Collection.
