Lab grown diamonds are authentic diamonds in every sense. All their physical, chemical, optical, and atomic properties are identical to those of mined diamonds. The only difference is that they are made above ground instead of below ground. Lab grown diamonds are absolutely real diamonds. On the other hand, diamond simulants such as moissanites and cubic zirconia are not actual diamonds but merely resemble them because they do not have the same chemical & physical properties of a mined diamond.
