There is an array of diamond alternatives available on the market today. With so many options, it’s challenging to keep up with all of them and recognise the features and properties that make each variety different.
With the popularity around lab-grown diamonds increasing, interest in has naturally grown. Understanding the inherent differences can be beneficial when purchasing a mined diamond alternative, in terms of setting expectations and figuring out a budget. To make an informed purchase, read on for a comparison between cubic zirconia and lab-created diamonds:
Source or Origin of the Stone
Optically, physically and chemically, lab-form diamonds are identical to mined diamonds. Sharing the same chemical makeup means that their carbon is arranged in the same isometric crystal pattern. The only difference is their origin; one is mined out of the ground and the other is man-made in a laboratory.
Cubic zirconia on the other hand is the cubic crystalline form of zirconium dioxide. While zirconium on its own is often used in other products, like dental implants, the crystallized version creates the affordable diamond replica which most people are familiar with.
The Rainbow Effect
It’s important to note, there are more than a few affordable lab diamond rings available. However, Cubic zirconia (or CZ) is typically offered at the lowest price points. This is of course because they are not mined or lab-formed. But how do you tell the difference between these types of stones?
There are several differences to note. Firstly, they are made of completely different chemicals, and there’s a noticeable difference compared to diamonds. When looking at the stones side-by-side, CZ will give off a “rainbow effect.” This is usually a giveaway that the stone is not a lab or mined diamond.
Hardness
Cubic zirconia is much softer than mined or lab-formed diamonds. Diamonds have the most durability in mineral form and are considered a “10” on the Mohs scale of hardness. However, the cubic zirconia only scores an 8.5. This means they will scratch more easily and the stone may even become foggy or cloudy as time passes.
A key difference between these stones is that the price point varies greatly. A lab-grown diamond can cost up to 40 percent less than mined diamonds. However, CZs come in even lower on the price scale and are a great option for anyone with a limited budget.
When it comes to purchasing a diamond, either lab-grown or mined, or cubic zirconia, there’s no question that each stone has its benefits. Consider factors such as budget, appearance and style when deciding which type of stone to purchase. Whether it’s a gift for a loved one or something special for yourself, it’s good to know there’s an option for everyone.
