Known as a diamond look-a-like and a stone with a realistic appearance, Cubic Zirconia is the first compound that approximates the radiance and clarity of diamonds.
Cubic Zirconia, also known as Cubic Zirconium or CZ is an artificial gemstone made in the form of cubic zirconium dioxide. Due to the rarity of the natural form of Cubic Zirconia, all Cubic Zirconia used in jewelry is synthetic or manmade. It is generally colorless and hard. It can, however, be colored in different ways.
It was discovered by German mineralogists in metamict zircon as microscopic grains. The metamictization process was believed to be the cause of its formation. However, an X-ray diffraction experiment verified the discovery, demonstrating the existence of a parallel natural product to the synthetic.
•Known as ‘the stone of practicality’, some practitioners use it as a tool for grounding.
•Cubic Zirconia can also provide release from illusions and selfishness.
Note- In the opinion of most astrologers, Cubic Zirconia is an ineffective substitute for diamond, however Natural Zircon is usually the better choice.
The abundance of Cubic Zirconias and their synthetic nature make them relatively inexpensive. This stone costs about Rs 150 per carat. It is easy for these stones to scratch and fade, losing their luster after about two years. Therefore, it is wise to buy a high-quality stone to maximize its benefit.
Cubic Zirconia crystals are usually clear or colorless. But in recent years, those stones are available in every color, as adding minerals to create colors has greatly simplified the process. Cerium is used to make red, yellow, and orange colors while chromium is used to make green. Alternatively, titanium can also be used to produce a golden brown color.
In terms of clarity, Cubic Zirconia is regarded as ‘too perfect’ since they are flawless and have very few natural imperfections. The reason is that they are made in a lab using manmade labor as opposed to being created naturally. As a result, their almost flawless nature makes them shine brighter than comparable diamonds.
Cubic Zirconia is generally weighed by millimeters rather than by carats. It is because a diamond of the same size weighs approximately 1.7 times more than Cubic Zirconia.
Cubic Zirconia’s cut varies from diamonds. In general, Cubic Zirconia is cut with smooth or rounded corners.
Refractive Index and Dispersion –
Refractive Index is angles at which light bends when it enters a gemstone, contributing to brilliance, while dispersion is when light passes through a gemstone and is scattered, creating a gem’s fire/brilliance. Brilliance refers to white light, while fire refers to colored light.
Cubic Zirconia has a significantly lower refractive index. Unlike diamonds, Cubic Zirconia has very little reflection back to the eye. Additionally, it has a higher dispersion which creates a ‘rainbow effect’ in the stone, causing the stone to reflect far too much-colored light.
