What is a Lab-Grown Diamond?
May 7, 2026
Lab-grown diamonds are real diamonds. Learn how they are made and how they compare to mined diamonds.
Lab-grown diamonds are real diamonds. They have the same chemical and physical properties. They are made in a lab, not mined. There are two processes. High pressure, high temperature (HPHT) mimics the Earth's crust. Chemical vapor deposition (CVD) uses gas. Lab diamonds are less expensive. They can be 30 to 40 percent cheaper than mined stones. They are more sustainable. They do not require mining. They are more ethical. There is no risk of conflict diamonds. The only way to tell the difference is with specialized equipment. The naked eye cannot tell. Lab diamonds are not fake. They are real. Cubic zirconia and moissanite are diamond simulants. They are different stones. The choice between mined and lab is personal.
