Cubic zirconia, commonly referred to as CZ, is a mineral that is man-made. This artificial substance is the cubic crystalline form of a compound called zirconium dioxide. CZ is widely used as a diamond stimulant because of its visually flawless and colorless state. This is why cubic zirconia is commonly referred to as the cheap man’s diamond. However, it can be made in a wide variety of colors so that it can be used in many different ways.
The history of cubic zirconia is an interesting one. It was discovered in 1892 in its natural form, the yellowish monoclinic mineral called baddelyite. Because it was so rare, it had little economic important.
Growing CZ artificially was a challenge due to the mineral’s high melting point. No existing crucible could hold cubic zirconia at its molten state. In 1899, German mineralogists discovered another naturally-occurring form of cubic zirconia: microscopic grains.
In
The process that the Soviets used is called skull crucible. It incorporates radio frequency induction coils, copper pipes, and other hardware which helps the crucible to be able to hold CZ in its molten state.
By adding certain metal oxide substances into the process, vibrantly colored CZ can be created. For example, adding cerium yields a red cubic zirconia gem, while adding chromium yields a green colored gem. Adding neodymium created a purple color, and adding erbium creates pink CZ. Finally, adding titanium in the process makes the CZ a golden brown color. This made cubic zirconia even more desirable in the market.
Think about the range of possibilities: cubic zirconia could be used to represent many different types of gemstones at a much less expensive cost. Jewelry makers, retailers, and enthusiasts across the world have discovered the sparkling benefits of utilizing CZ in their designs. Customers love the price as well as the look!
