What Are Lab-Grown Diamonds?

Consumers often confuse lab-grown diamonds with diamond simulants, such as Cubic Zirconia or Moissanite. These may look like diamonds, but are actually made from different materials. 

However, lab-grown diamonds have the same crystal structure and chemical composition as natural diamonds. When put next to each other, the look and sparkle is one in the same. 

The true difference is in the creation process. Lab-grown diamonds are created using technology that mimics the Earth's natural growing process in a controlled environment.

Lab-grown diamonds have the same chemical makeup as natural diamonds, only man-made.
