How Much Does a 5-Carat Lab Diamond Cost? (Updated 2023)

Last Updated on April 23, 2023 by LabGrownCarats

The cost of a diamond can vary significantly depending on its grade and the location of purchase. For instance, a lab-created diamond weighing 5 carats can cost anywhere between $5300 to $27000, based on its 4Cs and scarcity. Typically, a 5-carat lab-created diamond with a popular round brilliant cut shape costs about $6-8000, which is nearly 80% less expensive than a naturally-mined diamond.

Our comprehensive guide analyzes the pricing of 5-carat lab diamonds, including round brilliant and fancy-shaped diamonds. We review the costs from six of the best-priced websites for buying lab-created diamonds.

Investing in a diamond is a significant decision, and it’s important to make an informed choice about selecting the appropriate stone and finding the best deal. To assist you, we have developed several guides that provide helpful tips and suggestions.

The essentials – the diamond 4Cs

To start your education on diamonds, learning the 4Cs is fundamental. We suggest beginning with our guide on lab-grown diamonds. However, if you are short on time or solely interested in the pricing of a 5-carat lab diamond, feel free to skip ahead.

The 4Cs of diamonds (applicable to both mined and lab-grown diamonds) are:

If you need a quick refresher, remember these three things about lab-created diamonds:

  • The primary feature of diamonds, particularly for all brilliant cut diamonds, is their brilliance. 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.
  • When assessing a diamond’s quality, size is not the most critical factor. Instead, the 4Cs of diamond quality, which are 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.
  • Whenever possible, opt for diamond weights that are slightly below the commonly sought-after sizes. Avoiding the round weights can result in significant cost savings without any noticeable difference. For example, you can choose a 4.89-carat diamond instead of a precisely 5.0-carat diamond.

We have compiled price information for 5-carat lab-created diamonds from the best online lab diamond sellers in 2023 to give you an estimate of their cost. Our example diamond is a lab-created round brilliant-cut diamond with the following 4C grades:

While our example diamond may not be the perfect fit for everyone, it provides a useful idea of how to differentiate between the 4C attributes of diamonds.

Cost of 5-carat fancy-shaped lab diamonds

Lab-grown diamonds are available in various shapes and sizes, with the round brilliant cut being the most popular. However, there are numerous other shapes of lab-created diamonds, collectively known as fancy shapes, which refer to any shape other than the round brilliant. In our lab-grown diamond shape guide, we explained how each shape has its unique beauty, advantages, and disadvantages.

While some lab-grown diamond shapes, like the heart shape, may be more expensive than the round brilliant cut, others, such as the emerald shape, can be more affordable. To help you compare the costs of the most popular fancy shapes, we have compiled the average price of all 5-carat fancy-shaped lab-grown diamonds.

As fancy-shaped diamonds are evaluated differently and have less strict cut grading compared to round brilliants, we have adjusted the ranges below. Specifically, the cut rating now includes “very good,” which would not be acceptable for a brilliant round cut.

Note that the below prices are starting prices and increase with quality. But, they provide an indication of the price range, and all diamonds will have at least the specifications listed.
