Lab-grown diamonds, also known as synthetic or cultured diamonds, are real diamonds that are created in a laboratory setting rather than mined from the earth.

Chemical Composition:
Lab-grown diamonds have the same chemical composition as natural diamonds: pure carbon crystallized in a cubic structure.

Physical Properties:
They exhibit identical physical properties, including hardness, brilliance, and fire.

Optical Properties:

They have the same optical properties, meaning they refract and disperse light in the same way as natural diamonds.

Grading:
Lab-grown diamonds are graded using the same 4Cs as natural diamonds: carat, color, clarity, and cut.

Identification:
While they appear identical to the naked eye, sophisticated laboratory equipment can distinguish between lab-grown and natural diamonds.
