Are lab-grown Diamond Carat and Size the Same?

How Does a Lab-Grown Diamond's Weight Affect its Prices?

The following factors will help you understand the elements that influence its pricing:

  1. Rising Cost Per Carat: Whether a diamond is traditional or lab-grown, it's a universal rule that the heavier the weight, the more expensive it will be. Larger diamonds are generally more costly because they require more resources and time to grow. For instance, a 4 carat lab-grown diamond costs significantly more than a 3 carat lab-grown diamond, not just double the price but exponentially more due to its rarity.

  2. Market Demand: Certain carat weights, like 2 carat lab-grown diamonds, are particularly popular for engagement rings and other subtle jewellery. However, because of their popularity and demand, their prices shoot up despite being lighter in weight.

  3. Cut Quality: The cut quality of a diamond affects its brilliance and how large it appears. A well-cut large diamond can reflect light better, making it seem more brilliant. Hence, it is more valuable. Conversely, despite its weight, a poorly cut diamond may appear smaller and less brilliant, reducing its price.

  4. Clarity and Colour: As diamonds increase in size, imperfections like inclusions and colour tints become more noticeable. Therefore, larger diamonds often require higher clarity and colour grades to maintain their visual appeal, raising their price. On the other hand, a large diamond with poor clarity or colour may be less expensive.

What are the Magic Numbers of a Lab-Grown Diamond Carat?

Magic numbers refer to specific carat weights at which the price of diamonds tends to increase. These points or numbers are important because lab diamonds India at or just above these weights are often much more expensive per carat than those just below.
