What is Cultured diamonds?

Cultured diamonds (also known as laboratory-grown diamonds or synthetic diamonds) are indeed real diamonds, just with a different formation process compared to natural diamonds.

The IGI also provides certification and grading services for cultured diamonds. The main characteristics of cultured diamonds are as follows:

Chemical composition: Cultured diamonds have the same chemical composition and crystal structure as natural diamonds.
Physical properties: Cultured diamonds possess the same physical properties as natural diamonds, such as refractive index, hardness, etc.
Artificial cultivation: Cultured diamonds are grown in a laboratory environment, using methods such as high-temperature high-pressure or chemical vapor deposition.
IGI certification: The IGI issues specialized certification reports for cultured diamonds, indicating that they are laboratory-grown.
Therefore, IGI-certified cultured diamonds are indeed real diamonds, just with a different formation process than natural diamonds. The IGI certification can help consumers understand the origin of the diamond. However, whether it is a natural diamond or a cultured diamond, their essential characteristics are the same.
