You must have come across Cubic Zirconia recently. Most people now prefer CZ over diamond rings. It is now widely used in gold and silver jewels. Its major advantage is, it looks exactly like real diamonds. Hence, it gives a royal and luxurious look. Due to its similarity, many people find it difficult to find the difference. It may look similar at a distance, but there are a few differences in physical structure and quality.

Since most of the properties of Cubic Zirconia stones are similar to diamonds in naked eyes, people might get tricked. Firstly, it is important to understand what Cubic Zirconia is.


Cubic Zirconia was first discovered in 1899, but it was introduced into jewelry production only in the ‘70s. These are synthetic gemstones made of cubic crystalline( a form of zirconium dioxide). Unlike real diamonds, CZs are lab-grown gemstones.


Though each lab follows a unique method, Cubic Zirconia is made by melting zirconium oxide powder with stabilizers such as magnesium or calcium. Once the crystals are stabilized, it is then cut and polished.


It can be mimicked to many shapes of diamonds such as an oval cut or cushion cut. Colored versions of CZ are also found.

It is often referred to as an inexpensive diamond. An untrained eye might tell they are identical, but CZ and diamonds are two entirely different stones. Here is how,


• Cubic Zirconia is a man-made synthetic gemstone created in the laboratory to look exactly like a diamond. But the diamonds are naturally found on the earth’s surface.

• CZ is a crystalline form of Zirconium oxide and looks flawless, hard, and looks pretty similar to a diamond.

• The edges of the diamonds are usually sharp and crisp, whereas the edges of CZ look more rounded and smoother.

• Diamonds are naturally imperfect, they are flawed and impure. They might also have hues of particular colors. But since CZ is made of synthetic matter, it looks colorless, flawless, and free of impurities.

• The first thing that indicates whether the crystal you have chosen is a real diamond, Swarovski crystal, or Cubic Zirconia, is the price. Cubic Zirconia is cheaper compared to other crystals like diamonds.

• Diamonds might project a more white light, whereas the Cubic Zirconia stones might project rainbow colors because of the excessive light dispersion.

• The refractive index of CZ is much lower compared to diamonds.

• Diamonds are highly durable and resilient.

• Cubic Zirconia is slightly denser than diamonds.

• CZ might be more susceptible to wear and tear compared to diamonds.

• CZ cannot withstand the same heat as a diamond.

• A white light reflection is called brilliance and a colored light reflection is called fire. Diamonds radiate more brilliance compared to CZs, irrespective of the size.


If you are someone who is looking for a cheaper but high quality diamond alternative, Cubic Zirconias are the best option. You might also have seen people preferring CZ for their engagement rings.
