Cubic Zirconia is well known as a substitute for diamond, due to its high hardness and great fire. But in recent years, it has established itself as a gorgeous gem in its own right. Check out the sheer sparkle of human ingenuity in our collection of cubic zirconia jewelry in combination with other semiprecious gemstones and sterling silver. Cubic zirconia is a beautiful synthetic gemstone that is durable and inexpensive and now even comes in any color of the rainbow, making it even more desirable. Cubic zirconia is a cubic form of zirconium oxide that is created in a laboratory, thus it is not a mineral. However, it was found naturally occurring once at one site in the 1930's. CZ is about 75% heavier than diamond.
