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 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 want to know how much a 2-carat lab diamond costs, you can skip ahead.
In short, the (lab) diamond 4Cs are:
- Diamond cut
- Diamond clarity
- Diamond color
- Diamond carat
If you need a quick diamond-buying refresher, keep these three 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 regarding diamond quality. When determining the quality of a diamond, the 4Cs of diamond quality—cut, clarity, color, and carat—should all be considered in that order. 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.
How We Researched Diamond Prices
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 2024. Our reference diamond is a round brilliant-cut lab-grown diamond with the following 4C grades:

April 2026 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 called fancy cuts, are any shape other than round brilliant. As discussed in our guide to lab diamond shapes, each has unique beauty, advantages, and disadvantages.
Like heart-shaped lab diamonds, some shapes 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 prices below are starting prices and go higher. But they give you an idea of the price range, and all will have at least the minimum specifications above.
| Lab diamond jeweler | Oval | Emerald | Pear | Princess | Radiant | Cushion | Heart |
|---|---|---|---|---|---|---|---|

Why Choose a Lab-Grown Diamond?
To begin with, lab diamonds are up to 60-80% less expensive than their mined counterparts with identical diamond 4C grading. And if you’re lucky, you could save even more money with lab-grown diamond deals. We monitor the market closely and are the first to know when diamond sellers announce specials or bargains. Sign up below to be notified of new lab-grown diamond discounts.
Additionally, it is not just the lower pricing that makes lab-created diamonds superior to mined diamonds. They are also more environmentally friendly and have a more positive impact on society. You may find out a lot more about it in the following articles:
- Why lab-grown diamonds are the sustainable, environmentally, and ethical diamond choice
- What You Need To Know Before Buying a Lab-Grown Diamond
Sustainable 2-Carat Lab Diamond Prices
Lab-grown diamonds are the best choice if you’re looking for ethical and sustainable options. But for complete sustainability, you may 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 those of 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 that Vrai is not as good (see also our review of Vrai).
Pandora, too, focuses on sustainability, as you can read in our Pandora Diamonds review, but they do not quite live up to Vrai or Brilliant Earth.
