This is a HIGH quality ring, based on the original Harry Winston for "Jennifer"! The ring is centered by a stunning 6 Carat (13MM x 13MM) emerald-cut Blue Zircon CZ, dazzling & brilliant to behold, and surrounded by clear and blazing Cubic Zirconia baguettes, which frame it perfectly! All of these dazzling stones are prong-set for added durability, and the Platinum overlay provides not only a gorgeous, high polished sheen to this ring, but also provides protection against tarnishing with age. This ring will NOT tarnish, and these Russian CZs will NOT discolor with time!
