What is Cz or AD Jewelry?
Cz or Cubic Zirconia Jewellery which is also known as American Diamond or AD Jewellery, is a type of Imitation Jewellery that is made with Lab Created Gemstones called Cubic Zirconia. Both Cz and AD or American Diamonds are the same. Kindly note that these are not real 'Zircons' which are mined gemstones.
Cubic Zirconia crystals are made by melting powdered zirconium and zirconium dioxide together and heating them up to 4,982°F. It is technically Zirconium Oxide and is made in crystalline form for use in Jewellery. Both Cz and AD or American Diamonds are the same. Kindly note that these are not 'Zircons' which are mined gemstones. While white colour AD / Cz is the most abundantly used, Green (which are made to look like Emeralds) and Red (which are made to look like Ruby) are also very common. Other colours include Blue, Black, and Champagne etc. While White is crystal clear Green and Red Cz stones are manufactured in a slightly translucent form to give them the look of real Emeralds and Rubies (which are seldom available with full clarity). Theses stones are hard and much superior to other ‘glass' stones used in other forms of Imitation Jewellery. They can withstand the tough heating conditions which are necessary in the manufacturing process of AD / Cz Jewellery. They are made to bear a heat of 750 degree Celsius without affecting the shine and lustre of the stone. Even Swarovski crystals are Cubic Zirconia stones, but the cut and polish of Swarovski stones are superior to normal Cz Stones commonly used by Manufacturers.

Following are the details of Zirconium Oxide or Cz / Ad stones:
Chemical Composition: ZRO2
Refractive Index of 2.5 to 2.8.
Melting Point: 2700 degree Celsius.
Hardness of 8.5 on Moh's Scale which means they are harder than many gemstones. Dispersion or 'Fire': 0.065 more than a diamond which is 0.044.
