How Big Can Lab Grown Diamond Be in Size?
Big diamonds attract more attention compared to smaller diamond sizes. But how big can lab-grown diamonds be in size? What are the possibilities? What makes diamonds big or small? And how do the other factors, such as the 4Cs and lab-grown diamond cost, relate to its size?
We explore the answers to all these questions in this blog.
How big can lab grown diamonds be in size?
Lab created diamonds, when first discovered, many decades ago, were smaller in size than the lab made diamonds we see today. Over time, thanks to advanced technology and rising customer demand, the size of lab grown diamonds has been able to overcome the size limitations.
With advanced technologies to grow diamonds in laboratories, such as the CVD and HPHT processes, the sizes of diamonds have grown significantly. Customers can now customize the size of their lab grown diamond based on their preference and budget.
For instance, if a customer wants a 2 carat lab grown diamond within a specific price, they can easily get a diamond made in a laboratory.
Diamond sizes can range from 0.25 carats to 40 carats. Here’s an illustration that comparatively shows some of the sizes of lab grown diamonds.
But how is a diamond of the desired size grown? Let’s find out.
How is a lab grown diamond of a desired size grown in a lab?
In this section, we explore the various factors that lead to a lab created diamond.
1. The diamond seed
The process of growing lab diamonds starts with the selection of a diamond seed. The seed plays a key role. A crystal seed is placed inside a special chamber to initiate the diamond-growing process. The dimensions of the seed have an impact on the final size of the lab grown diamond. Larger seeds typically result in the growth of larger diamonds, while smaller seeds tend to produce smaller ones.
2. Time taken to grow a diamond
The next critical factor in the size of the lab grown diamonds is the time taken to grow them.
The longer the seed is allowed to grow, the larger the final diamond size. However, while extended growth time can sometimes result in larger diamonds, there is also a risk of imperfections in the diamond that can potentially compromise the lab created diamond’s quality.
3. Pressure and temperature
When going through the CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) processes, the seeds can get impacted. When there is precise control of temperature and pressure on the diamond seed, the size of the lab made diamond can be controlled too.
4. The ratio of gases
The diamond seed is also put through different types of gases. The ratio of gases can also influence the size of the lab created diamonds. For instance, the ratio of other gases and carbon can make a huge difference to the size of the diamond. Hence, it is essential to control the ratio of gases in the diamond-growing chamber.
5. Cutting and polishing
Once the raw diamond is grown, the next steps involve cutting and polishing. Both these processes play a critical role in determining the size of the lab grown diamond. Skilled craftsmanship is essential to maximize the size of the rough diamond while ensuring quality, brilliance, and other key attributes.
