Lab-Grown Diamonds

What Are Lab-Grown Diamonds?

Lab-Grown Diamonds are optically, chemically, and physically, identical to natural diamonds and are created in a lab by scientists. Lab-grown diamonds provide the same luxurious diamond at flexible price points to fit anyone’s lifestyle. Lab-grown diamonds also offer the opportunity of a larger carat weight at lower costs.


Indistinguishable from the naked eye, lab-grown diamonds present the same visible qualities as their natural counterparts.


Lab-grown diamonds are not simulants. They are formed from rough crystals taking an average of 2–4 weeks.


To confidently tell lab-grown and natural diamonds apart, advanced instruments are needed to detect the physical aspects.
