Usually, about the appearance, Cubic Zirconia is so optically close to diamond that even jewellers cannot tell the difference between a Cubic Zirconia and a diamond with the naked eye - jewellers use a loupe to tell the difference. But the cost of Cubic Zirconia jewelry is just a fraction of the cost of jewelry containing real diamonds. So Cubic Zirconia jewelry started to become popular during the 1980's. Most of our sparkly stud earrings and necklace pendants are made of high quality Cubic Zirconia, not the cheap glass which is dimmer when you are wearing for several days. Besides, we have the stable suppliers to make sure the qualities, so please confirm again whether order is sold by JewelrieShop at checkout. About JewelrieShop Customer Service 1.
