For consumers, whether to choose natural diamonds or laboratory-grown diamonds is a question.

Rough Lab Grown Diamonds Introduction
Lab Grown Diamond is a mono crystalline diamond made of diamond crystals with a diameter of 10 to 30 nanometers. In the early stage, man-made diamonds showed a light color of sugar due to the nitrogen atoms in the air entering into the diamond crystal. Through the improved production method of scientists, there is no difference between man-made diamonds and natural diamonds in appearance now.
