How much does a lab-grown diamond engagement ring cost in 2024? Well, the price can vary significantly depending on the stone’s grade and where they are purchased.

Diamond engagement rings 101 – the diamond 4Cs
Starting your diamond education with the 4Cs is fundamental. We recommend beginning with our lab-grown diamond guide. However, if you’re short on time or only interested in the price of engagement rings, feel free to skip ahead.
The 4Cs of diamonds (applicable to mined and lab diamonds alike) are:
- Diamond cut
- Diamond clarity
- Diamond color
- Diamond carat
If you need a quick refresher on lab-created diamonds, remember these three things:
- The primary feature of diamonds, particularly for all brilliant cut diamonds, is their sparkle. Although brilliance is not the most crucial factor for some fancy-shaped and fancy-colored lab diamonds, the diamond’s cut grade remains essential. Therefore, we always recommend prioritizing the cut grade over the diamond’s size when purchasing a lab-grown diamond.
- Size is not the most critical factor when assessing a diamond’s quality. Instead, the 4Cs of diamond quality– cut, clarity, color, and carat- should be prioritized in that order. First, look for the highest-quality cut, followed by color and clarity grades, with carat weight being the least important.
- Opt for diamond weights slightly below the commonly sought-after sizes whenever possible. Avoiding the round weights can result in significant cost savings without any noticeable difference. For example, you can choose a 0.96-carat lab diamond instead of a precisely 1.0-carat diamond.
Next, let’s learn how much the rings cost.

Where to buy the best sustainable lab diamonds?
If you are looking for sustainable diamonds, Brilliant Earth is one of the best places to buy sustainable and climate-neutral lab-grown diamonds.

Vrai is another good option, but when comparing Brilliant Earth and Vrai, we found that Brilliant Earth is a better option for sustainable diamonds and diamonds in general (see our Vrai review).
