Understanding lab diamond quality – the diamond 4Cs
If you’re beginning to learn about diamonds, we suggest starting with the diamond 4Cs, and our intro to lab-grown diamond guide is an excellent place to start. However, if you’re short on time or only interested in the pricing of a 0.75-carat lab diamond, you may skip ahead.
The 4Cs of diamonds apply to both mined and lab-grown diamonds and include:
For a quick refresher on buying lab-grown diamonds, keep these three points in mind:
- The primary feature of diamonds is their brilliance, particularly for diamonds with a brilliant cut. While brilliance is less important for some fancy-shaped and fancy-colored lab diamonds, the cut grade remains crucial for all diamonds. Therefore, we always recommend prioritizing cut grade over diamond size when purchasing a lab-grown diamond.
- When it comes to diamond quality, size isn’t the most important factor. The 4Cs of diamond quality – cut, clarity, color, and carat – should be prioritized in that order when assessing a diamond’s quality. Focus on obtaining the highest possible cut grade, followed by color and clarity grades, and lastly, carat weight. With fancy-colored lab diamonds, the color grade is usually the most critical factor.
- Whenever possible, consider selecting diamond weights that are slightly below the most popular sizes. Opting for non-round weights can result in significant cost savings as the size difference is barely noticeable. For example, choosing a 0.71-carat diamond instead of an exact 0.75-carat diamond.
To provide you with a cost estimate, we have gathered pricing information on 0.75-carat lab-created diamonds from the best online lab diamond vendors in 2023. Our reference diamond is a lab-created round brilliant-cut diamond with the following 4C grades:
- Carat weight: 0.75(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)
While our diamond example ranges may not be the best fit for everyone, they can be a good indicator of prices (and how to compare the 4Cs of lab diamonds).

Cost of 0.75-carat fancy-shaped lab diamonds
Lab-grown diamonds are available in various shapes, with the round brilliant-cut diamond being the most popular. However, lab-created diamonds come in several other shapes, known as fancy shapes or cuts, which include any shape other than round brilliant. In our guide to lab-grown diamond shapes, we explain how each shape has its unique beauty, benefits, and drawbacks.
The prices of fancy-shaped lab-grown diamonds can vary significantly. For instance, heart-shaped lab diamonds tend to be pricier than round brilliants, while shapes such as the emerald cut are more affordable. To help you compare the costs of the most popular fancy shapes, we have compiled the average prices of all 0.75-carat fancy-shaped lab-grown diamonds below.
Because fancy-shaped diamonds are evaluated differently and have less strict cut grading than round brilliants, we have adjusted the ranges below to include a “very good” rating, which would not be acceptable for a brilliant round cut.
- Carat weight: 0.75 (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
The below prices are starting prices and will increase with higher quality, but they give an idea of the price ranges at each retailer and the overall price levels of each lab diamond shape. All diamonds will have at least the minimum specifications above.
