The Russian Radiant Diamondz are formed through a complicated process from zirconium oxide and yttrium oxide. These two chemicals are melted together at temperatures of almost 5,000 degrees Fahrenheit, and then carefully cooled to create flawless crystals. It's the yttrium oxide that stabilizes the color and clarity of the cubic zirconium (CZ). Prior to the addition of yttrium oxide, CZs would cloud up with prolonged exposure to sunlight. Now, the Russian Radiant Diamondz will maintain their color and clarity for many years.
Our Russian CZs are the finest cubic zirconium available!
Just as there are many different grades of diamonds, there are also many different grades of cubic zirconium. Superior cutting and polishing, for maximum brilliance, create a noticeable difference between our Russian Radiant and the conventional grades of cubic zirconium which are mass produced and commercially cut with minimal finishing techniques. The Russian Radiant has dispersion greater than a diamond, and this produces an abundance of color play and "fire".
Selected from the finest CZ crystals, experienced cutters facet and hand polish each Russian Radiant to the same specification used for diamonds, set forth by the GIA (Gemological Institute of America).
You will always be assured that your Russian Radiant cubic zirconium is of the best quality and to the exact diamond cutting standards.
