Zircon vs Diamond: Unveiling the Brilliance Battle

Posted on June 23rd, 2023 04:13 PM

When we are eager to find zircon vs diamond, these two stones are completely distinct from one another for a variety of factors, including chemical characteristics, brilliance, and color. Let’s read how zircon is different from diamond.

  • Zirconia is frequently viewed as a less expensive diamond substitute; however, because it is a lab-grown material, it differs from natural diamonds in terms of aesthetics and physical makeup.
  • Zirconia is worth practically less in terms of the value of diamonds. A zirconia engagement ring's setting might be worth something if you tried to resell it. The zirconia gemstone has no commercial value, exactly like other diamond substitutes.
  • The market price of a diamond, on the other hand, continues to rise over time. Contrary to zirconia, diamonds can be handed down through the years as a cherished family heirloom. Because they are gorgeous and natural with an alluring beauty, diamonds have a set higher standard. In general, a diamond's 4 Cs determine its cost and value. These components combine to give the stone its aesthetic appeal and radiance.
  • Although the cost of diamonds and zirconia is drastically different, it is important to understand that the same is true of their qualities, qualities, and beauty. A reduced cost here does not necessarily equate to a greater value or offer.
  • Diamonds are the toughest substance known to man, naturally occurring, and exceptionally beautiful. Lab-made zirconia is available but not equally brilliant or enduringly beautiful.

What is zirconia?

Zirconia is colorless and naturally found within the mineral baddeleyite, but it’s extremely rare. In all zirconia jewelry, the gemstones are exclusively lab-created. To create  zirconia, zirconium oxide powder and stabilizers like calcium and magnesium are melted at 4,982 ºF. Crystals form and stabilize after being exposed to heat for hours. A genuine man-made gemstone is a zirconia. It is a hard, colorless crystalline form of zirconium dioxide. The crystals are then polished and sliced. The particular processes used by each laboratory to create zirconia vary. Diamond shapes like the Cushion Cut and Oval Cut can be curated with  zirconia. There are various colored varieties of zirconia.

How Can You Tell the Difference Between Zirconia and Diamonds?

Zircon vs diamond: The best approach to distinguish between zircon and diamond is to examine the gemstones in natural daylight. A diamond emits high white light or brilliance, whereas zirconia emits an apparent rainbow of colorful light. A crucial indicator that the stone is not a diamond is the extra light dispersion. Other methods for differentiating between diamonds and zirconia include examining their physical, chemical, and aesthetic characteristics. Making the best choices while creating and buying jewelry depends on your understanding of the distinctions.

Zircon vs diamond: Beauty and Brilliance

Zircon vs diamond

A diamond's cut, which affects how much light reflects through the diamond's table to your eyes, has a significant impact on how beautiful it is. Brilliance is the name given to the reflection of white light and fire to the reflection of colored light.

There is no precise sparkle or fire in zirconia. Compared to diamonds, which have a refractive index of 2.42, it ranges between 2.15 and 2.18. Zirconia indicates how light travels through materials, providing far less reflection to the eye.
The stark difference in light reflection between the two jewels may be seen just by holding them up to a light source. For instance, no matter its size, the gorgeous diamond ring will sparkle more brilliantly than any  zirconia.

Moreover, the dispersion rate of zirconia is larger (between 0.058 and 0.066 as opposed to 0.044 for diamonds). The zirconia stone exhibits a "rainbow effect"—that is, it reflects an excessive amount of colored light—due to the enhanced dispersion. It is simple to identify as a fake diamond because of the excessive light dispersion. Overall, compared to a diamond's unrivalled beauty and brilliance,  zirconia is incomparable. 

Zircon vs diamond: Difference of Durability and Density

Diamonds are the world's hardest naturally occurring mineral, scoring a perfect 10 on the Mohs scale of hardness. Diamonds are exceptionally strong and sturdy, which makes them perfect for everyday wear as engagement rings. Diamonds require little maintenance to keep their brilliance and beauty.

On the other hand, zirconia has a Mohs hardness rating of 8.5. It gives some durability due to the fact that it is a synthetic substance. It can be used to make jewelry, but it won't last as long as a diamond. For instance, zirconia ages with scratches and cloudiness.

Zirconia is slightly denser than diamonds. By weighing the stone on a scale, a jeweler or gemologist can easily tell a CZ stone from a diamond. Depending on the shape of the gemstone, a 1 Carat diamond ring can appear a little bit bigger than a 1 Carat  zirconia.

Zircon vs diamond: Difference of Clarity and Color

Since zirconia is created in a laboratory, it does not have the same inherent flaws that diamonds do. Because perfect diamonds are so rare and valuable, they are very pricey. Although some people may think  zirconia is flawless, most people think it's "too perfect". If you're shopping for a diamond, we advise picking one that is eye clean, which means that any flaws or imperfections are invisible to the naked eye. Although you have the option to select a higher clarity grade, doing so will cost you money for unnoticed features. We often advise searching for a diamond that can be a magnificent Princess Cut halo ring depending on your Diamond Shape and the style of setting. Because it is produced in this manner, zirconia is regarded as being colorless. However, these man-made stones frequently reflect light that has an orange tint to them, which is yet another unmistakable sign that they are not genuine diamonds.
