Cubic Zirconia, also referred to as CZ and Cubic Zirconium is a bright man-made gemstone that is often used as an affordable simulant or replacement for real diamonds. Developed for its intense clarity and sparkle, it was originally intended to be used as an optic for lasers in military operations. Cubic Zirconia can be made in a sparkly rainbow of colors so it looks great with just about any similar colored gemstone. Metaphysically, Cubic Zirconia is said to bring light, joy, and positivity to the wearer. It is also used to boost intuition during meditation and support the solar plexus and crown chakras.
