Understanding synthetic diamond prices

The 4Cs are the first thing you should learn about lab-created diamonds. However, you can skip ahead if you are in a hurry or want to know how much you will have to pay for a synthetic diamond. We recommend starting with our easy-to-read guide to the 4Cs of synthetic diamonds.

Diamond cut
Diamond clarity
Diamond color
Diamond carat

Consider these three things when shopping for a synthetic diamond if you need a quick diamond-buying refresher.

– You should first understand that diamonds are all about the sparkle, also known as brilliance or fire in the diamond industry. Diamonds are distinguished by their radiance. Always prioritize brilliance over size. For example, choose a 0.96-carat lab diamond over a 1.0-carat lab diamond. So, when determining the quality of a diamond using the 4Cs of diamond quality, prioritize the best cut possible, followed by color and clarity grades, and finally, carat weight. Even if you are purchasing a non-brilliant diamond shape, you should strive for a well-cut diamond. Avoiding round weights can save you a lot of money, and the best part is that no one will notice. A higher-quality lab diamond appears larger. – Quality is more important than quantity! So, if you only remember one thing, make it this: always go for the best diamond cut grade possible! Furthermore, a low-quality diamond will not appear to be a diamond! Buy a large brilliant-shaped diamond with poor brilliance instead. – If possible, choose a synthetic diamond with a weight slightly lower than the popular “round” weights.

Now that you understand why synthetic diamond costs fluctuate let’s compare pricing for various synthetic diamond carats. We regularly collect and update synthetic diamond prices from the leading online diamond jewelers.

Using a reference diamond, we compare the pricing of synthetic diamonds. A round brilliant-cut lab-grown diamond with the 4C grades we suggest for most lab diamonds serves as the reference synthetic diamond. They are as follows:

Carat weights: 0.5 to 6.0 (plus-minus a little)
Cut grade: Excellent or Ideal (whichever is the best, depending on the laboratory)
Color grade: I-J
Clarity grade: VS1-VS2
Shape: Round Brilliant
Origin: Lab-created

Our reference diamond may not be the best for every jewelry necessity, but it is what we propose for the most common lab diamond jewelry demands. Just be careful not to reduce the diamond cut grade! Expect to pay more for higher-grade synthetic diamonds and less if you relax them.
