Cubic Zirconia, or loose CZ for short, goes back to 1937. It
is a man-made composition to simulate the Diamond. Due to a hardness of 8.5
on the Moh's scale and modern technical advances it became a high quality, inexpensive,
beautiful gemstone and one of the major products in the jewelry industry. Our
very best highest quality AAA-Zirconia is a very fine, loupe clean product,
which could match or surpass many expensive diamonds.
All our Zirconias are IF (Internal Flawless) - Lupeclean. That is the highest
ranking in diamond grading.
