While the brilliance and shape of a lab-grown diamond are undoubtedly important, it's crucial to understand that they are not the sole factors influencing the cost of a synthetic diamond. The most pivotal factor is the Carat, which directly impacts the market price of a lab-grown diamond.
Of the 4C's, Carat is one of the C's that helps determine the market price of a lab-grown diamond.
What is a Lab-Grown Diamond Carat?
A diamond carat is the measurement unit used to specify a diamond's weight. In simple terms, carat is the measurement of a lab-grown diamond's weight. So, 1 carat (or ct) of a lab-grown diamond weighs 0.20 grams or 200 milligrams.
Here are some lab-grown diamond carat measurements for you to understand better:
- 1 carat lab-grown diamond = 200 milligrams / 0.20 grams
- 2 carat lab-made diamond = 400 milligrams / 0.40 grams
- 3 carat lab-created diamond = 600 milligrams / 0.60 grams
- 4 carat lab-grown diamond = 800 milligrams / 0.80 grams
Are lab-grown Diamond Carat and Size the Same?
It's a common misconception that a lab-grown diamond's carat weight and size are the same. In reality, a carat's weight is a reflection of the stone's size, but they are not synonymous terms.
Carat measures weight, whereas size refers to a lab created diamond's physical dimensions and appearance. For instance, two lab-grown diamonds India of the same carat weight may appear to be different sizes because of their cut and shape.
How Does a Lab-Grown Diamond's Weight Affect its Prices?
The following factors will help you understand the elements that influence its pricing:
-
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.
-
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.
-
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.
- 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.
The magic numbers in lab-created diamond carat weights are available in 0.25 ct increments, such as 0.50 ct, 0.70 ct, 0.50 ct, 0.75 ct, 1ct, 1.25 ct, 1.50 ct, 1.75 ct, 2 ct, and so on. This means that the price of a 1 carat lab-grown diamond will be much more than 0.75 ct lab diamond.
It is important to understand that these magic numbers serve as psychological benchmarks for consumers. Even though the cost of lab diamonds is at a magic number, demand increases the prices.
Which is the Best Carat Weight for a Lab-Grown Diamond?
The best lab-grown diamond carat weight depends on your preferences, budget, and requirements. If you are looking for everyday jewellery, you can buy a 1 carat lab-grown diamond ring or earrings.
