Diamond vs. Cubic Zirconia – the top 7 differences you should know about

The availability of diamond substitutes like Cubic Zirconia and Satéur™ has made it exorbitant to spend huge sums of money on a diamond. These two gemstones look exactly like a diamond to the naked eyes. In fact, there have been a lot of discussions on Cubic Zirconia vs diamond difference and why you should or shouldn’t get one of them. The most common diamond substitutes are, of course, Satéur™ or Cubic Zirconia (CZ).

Cubic Zirconia vs. Diamonds – What you should know

Diamonds come in two forms, the natural and the man-made varieties. In terms of look and composition, both are similar. Natural diamond is mined from reserves in the earth while man-made diamonds are made in the lab. These two varieties of diamond are similar in most ways. However, natural diamond is expensive because of their natural occurrence and rarity. Lab-made diamond is cheaper and more accessible in the jewelry market place.

Cubic Zirconia looks like diamond but it isn’t. It is fully lab-made and has few things in common with diamond apart from looking like it from a distance. While diamonds are made of Carbon, Cubic Zirconia is made from Zirconium Oxide. The debate of Cubic Zirconia vs diamond is one that will never end as both gemstones has their advantages and disadvantages.

Satéur™ Stone looks most like diamond and the Ultimate Stone 2.0 version passes a diamond tester without issues. As far as we can tell, this is the stone that comes closest to a diamond.

For Cubic Zirconia though, the good thing about it is the fact that it’s lab-made and has no conflict history or ethical and sustainability issues like natural diamond which often have some shady history

Cubic Zirconia vs. Diamonds – Durability

Diamonds are more durable than Cubic Zirconia in terms of toughness. On the Mohs scale of hardness, diamond is rated 10 while Cubic Zirconia is rated between 8.0 and 8.5. This means that diamonds are tough and can be worn regularly without any fear of damaged, getting chipped or scratched compared to Cubic Zirconia. Diamond requires less maintenance but Cubic Zirconia needs to be shined more often to maintain its brilliance. When durability is what you’re looking at, diamond will offer you more on the long term. Cubic zirconia vs diamond price should be the determinant at this point.

Cubic Zirconia vs. Diamonds – Color

Considering color, the fact that Cubic Zirconia is lab-made means that its color can be controlled to be as desired. Diamond on the other hand, occurs more naturally so it’s not as easy to get colorless diamonds. Such color stones are rare and expensive. For diamonds, they are graded on a color scale of D (colorless) to A (yellow).

This doesn’t mean that there aren’t colored Cubic Zirconia, you will find out that they’re as affordable as the colorless variety. Colored diamond is more expensive than the colorless or near-white versions.

Satéur™ Stone are colorless and look same as diamond to the naked eyes. This one stone that looks perfectly the same as diamond without the expensive price tag.

Cubic Zirconia vs. Diamonds – Clarity
Cubic Zirconia vs. Diamonds – Dispersion

When a gemstone is said to have fire, it refers to its ability to disperse light into different colors of the rainbow. This dispersion makes the stone to sparkle with fire. Diamonds have always been rated for their ability to brilliantly refract light, thanks for their dispersion rate of 0.044.

Cubic Zirconia has a higher dispersion rate pegged at 0.066. This makes Cubic Zirconia to have a tell-tale ‘rainbow effect’ dispersion when light hits it. This fact is another cubic zirconia vs diamond difference though it is less noticeable when the 2 stones are smaller in size. The distinction is more pronounced in larger stones

Some jewelry lovers don’t fancy the flash of colors exhibited by Cubic Zirconia and other diamond alternatives when it is hit by light. Not everyone loves a brilliance of colors as shown by these gemstones. Smaller stones have less colorful brilliance and should be considered in this case.
