CVD and HPHT Lab-Grown Diamonds
Lab-grown diamonds are famous for their affordability and quality, and their demand is also increasing. Lab diamonds are created using two methods, CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature). Those made using these two processes are real and high-quality, with physical and chemical properties similar to natural diamonds.
What is a CVD Diamond?
CVD Diamonds are made through the Chemical Vapor Deposition process. In this process, diamond seeds are put in a chamber filled with carbon gas. As soon as the temperature of the chamber goes up, the carbon atoms start breaking and get deposited on the diamond seeds. These diamonds are very pure and whiter.
What is an HPHT Diamond?
HPHT diamonds are created by replicating the natural diamond creation process in a lab. Carbon is injected at temperatures and pressures that create diamonds. These diamonds are larger in size and have a blue or yellow-toned color. This process is often used to enhance color in diamonds.

Which One Should You Choose?
If you like diamonds with exceptional clarity, you can go for CVD diamonds. If you prefer diamonds with unique hues or color enhancements, you can opt for HPHT diamonds. Both of these diamonds are of high-quality and 100% real.
Conclusion
Both CVD and HPHT are lab grown diamonds - quality and affordable. In this article, we have given all the details about both the processes and the diamonds made from them. Hope you found it helpful.
