What is a lab-created diamond?
Lab-created diamonds are real diamonds created in a highly controlled laboratory environment. They are physically, optically, and chemically identical to earth-mined diamonds, without the environmental cost and up to 50% less in price.
A helpful comparison would be to consider the difference between ice that is created in nature by environmental conditions and the ice created by your freezer. Both create "real" ice, the only difference is the point of origin. In either case, both forms are real ice, just like a lab-created diamond and mined diamond.
