Some diamonds ...
The process just takes way less time (we’re talking a few months as opposed to billions of years), and the lab-grown diamonds have the same physical and chemical properties as natural diamonds ...
Whether a gemstone is a natural stone or synthetic, the chemical, physical, and optical characteristics are the same: They are composed of the same mineral and are colored by the same trace materials, have the same hardness and density and strength, and show the same color spectrum, refractive index, and birefringence (if any).
