Lab created diamonds are real diamonds. They have the same optical, chemical, thermal, and physical features as mined diamonds. Lab created diamond engagement rings are beautiful, dazzling, and budget friendly. Lab created diamonds are also referred to as man-made diamonds, or cultured diamonds, are grown using advanced technology that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust. These highly controlled laboratory environments create man made diamonds that consist of actual carbon atoms arranged in the characteristic diamond crystal structure. Since they are made of the same material as natural diamonds, they exhibit the same optical and chemical properties.
