Our highest quality cubic zirconia gems are the finest available anywhere. All of our CZ gems are hand selected for their hardness and brilliance and are hand cut and polished to the same specifications as the best diamonds. We use only the original Russian cubic zirconia, known as Phyanite. This formula was developed by the Russians to use as an alternative to costly diamonds for use in laser optics in their space program. These CZ gems are extremely hard and have the same optical and physical characteristics as the best diamonds. All of our CZ gem jewelry is guaranteed for life to never lose their brilliance and luster and to never cloud as do many commercial CZ's. Remember, there are many grades of cubic zirconia, but only one Phyanite. Insist on the best! 14k Gold CZ Post Earrings 14k Gold CZ Filagree Stud Earrings 14k Gold CZ Dangle Filagree Leverback Earrings 14k Gold Phyanite CZ Basket Set Pendants 14k White and Yellow Gold Bezel CZ Post Earrings 14k Gold Filagree Phyanite CZ Pendants Thank you for shopping with VSC Jewelry.com.
