Cubic Zirconia, or CZ is a synthetic gemstone having optical characteristics that are very close to a natural diamond.
Though the raw material of all CZ is the same, top-quality faceting and polishing results in "lively" gems with a crisp, clean appearance.
CZ is an alternative birthstone to Diamonds for the month of April.
