Diamond costs vary greatly depending on the grade of the stone and where it is purchased. A 2-carat lab diamond, for example, can cost as low as $1000 or as much as $7500, depending on the diamond’s 4Cs and rarety. A 2-carat brilliant-cut round lab-grown diamond (one of the most popular carats and cuts) costs roughly $1500 on average, which is up to 89% cheaper than a mined diamond!
How much does a 2-carat lab-grown diamond cost?
2-carat lab diamond prices range from $1000 to $5000, depending on the quality. An excellent quality 2-carat lab-grown diamond costs around $1500-1800, which is up to 89% less than a mined diamond!

The cheapest places to buy a 2-carat lab-grown diamond
Purchasing a diamond is a significant investment, and it is critical to understand how to select the best stone and where to obtain the best value for your money. That’s why we’ve created several tutorials to assist our readers.
We recommend getting started by reading our popular buying guides below:

Understanding 2-carat lab diamond prices
The first thing you should know about diamonds is the 4Cs. We suggest that you start with our introduction to lab-grown diamonds. But, if you are in a rush or simply want to know how much a 2-carat lab diamond costs, you can, of course, skip ahead.
In short, the (lab) diamond 4Cs are:
If you need a quick diamond-buying refresher, keep these 3 things in mind:
- First, you should know that diamonds are all about brilliance, and diamonds are distinguished by their radiance, especially when it comes to all brilliant cut diamonds. Some fancy-shaped and fancy-colored diamonds do not sparkle in the same way, e.g., emerald-shaped or black diamonds. But, regardless of shape and color, if you only remember one thing, make it this: always go for the best diamond cut grade possible! Always prioritize brilliance higher than size.
- Remember, it’s not the size that matters most when it comes to diamond quality. When determining the quality of a diamond, the 4Cs of diamond quality—cut, clarity, color, and carat—in that order, should all be considered. So, first, aim for the best cut possible, then color and clarity grades, and carat weight last.
- If possible, go just below the popular weights. Bypassing round weights can save you a lot of money, and the best thing is that no one will be able to notice the difference. So choose a 1.93ct instead of a diamond that weighs exactly 2.0 carat, for example.
To give you an idea of the prices of 2-carat lab-grown diamonds, we have compiled prices from the best online diamond retailers in 2023. Our reference diamond is a round brilliant-cut lab-grown diamond with the following 4C grades:
- Carat weight: 2.0 (plus-minus a little)
- Cut grade: Excellent (GIA) or Ideal (IGI)
- Color grade: I-J
- Clarity grade: VS1-VS2
- Shape: Round Brilliant
- Origin: Lab-grown (of course)
Our reference diamond is not necessarily the best for you, but it gives a good indication of how to choose between the diamond 4Cs.

Prices for 2-carat fancy-shaped lab diamonds
Diamonds created in laboratories come in a variety of forms and sizes. While the brilliant-cut round diamond is the most popular, many different lab diamond shapes exist. Fancy shapes, sometimes referred to as fancy cuts, are any shape other than round brilliant. As we discussed in our guide to lab diamond shapes, each has its own unique beauty, advantages, and disadvantages.
Certain shapes, like heart-shaped lab diamonds, are more expensive than round brilliant, while others, such as radiant-shaped, are less expensive. To assist you in comparing the pricing of the most popular fancy-shaped lab diamonds, we have compiled the average price of all 2-carat fancy-shaped lab diamonds.
Because fancy-shaped diamonds are evaluated slightly differently, and cut grading is not as stringent as with round brilliants, we have revised the ranges below. Most notably, the cut rating includes very good, which we would never allow for a brilliant round cut.
- Carat weight: 2.0 (plus-minus a little)
- Cut grade: Very Good, Excellent, or Ideal (usually not independently graded)
- Color grade: I-J
- Clarity grade: VS1-VS2
- Shape: Fancy-shapes
- Origin: Lab-grown
All the below prices are starting prices and go higher, but it gives you an idea of the price range, and all will have at least the minimum specifications above.

Prices for sustainable 2-carat lab diamonds
If you’re looking for ethical and sustainable options, lab-grown diamonds are the best choice. But, for complete sustainability, you may want to consider lab-grown diamonds made with renewable energy, set in recycled metal, and packaged in sustainable materials. It’s worth noting that prices for sustainable lab diamonds are typically 30-40% higher than other lab-grown diamonds.
One of the best places to buy sustainable and zero-emission lab-grown diamonds is Brilliant Earth (read our Brilliant Earth review). Another option is Vrai, but as you can read in our comparison between Brilliant Earth and Vrai, we find Brilliant Earth is the best place for sustainable diamonds (see our review of Vrai). Pandora, too, focuses on sustainability, as you can read in our Pandora Brilliance review, but they do not quite live up to Vrai or Brilliant Earth.
