Lab-created diamonds and gemstones (also referred to as lab-grown or man-made) are identical to naturally occurring stones in every sense: chemically, physically, and optically.

The mineral composition of a lab-created diamond or gemstone is made with a process similar to what nature does beneath the earth over millions of years. However, it is done in a lab in a fraction of the time and for a fraction of the cost of mining.


 The average person would be extremely hard-pressed to tell the difference between a natural and lab-created stone. It takes a trained eye, high magnification, and other instruments. The result is a high-quality, lab-created stone at a price that’s significantly lower than its natural counterpart.
