This ring is amazing! Get two looks in one ring! Just open and flip the ring to change it to either red or blue stones. Stones: Only genuine Cubic Zirconia and Swarovski crystal are used to represent our diamond-like styles. We also use genuine stones such as tiger eye, onyx, opal, garnet, amethyst and sometimes ruby, sapphire or emerald. Beneath the Surface: The finish is the most important part of any piece of fine costume jewelry. Covenant rings have the best finish that money can buy. Every casting of brass-alloy or sterling silver is hand polished before going to the plate. Electroplating is a three-stage process; first copper, then nickel and finally pure gold or precious rhodium are electronically bonded to the surface of the ring. In the case of our brass-alloy rings, Covenant’s is the only factory that inspects each piece during the plating process. After copper is applied, each ring is re-inspected to be sure the surface has no flaws.
