Cubic Zirconia Violet Oval, CZ Violet Oval

Cubic Zirconia dates back to 1937. It is a man-made composition to simulate
diamonds. Due to a hardness of 8.5 and modern technical advances, CZ has become
a high quality, inexpensive, beautiful gemstone. The cubic zirconia violet color
is one of the more unusual products in the jewelry industry and our oval shaped
violet cubic zirconias are in high demand because of their stunning depth of
color.
