Lab Grown Diamonds are grown in highly-controlled laboratory conditions that simulate the earth’s natural growing environment, producing real diamonds that are optically, physically and chemically identical to earth mined diamonds, so its refractive index ,density ,hardness ,dispersion and crystalline structure are almost same as each other. Nowadays almost no jeweler, diamond merchant or even a customer with microscope can tell one apart from the other.
The properties of synthetic diamond depend on the details of the manufacturing processes; however, some synthetic diamonds (whether formed by HPHT or CVD) have properties such as hardness, thermal conductivity and electron mobility that are superior to those of most naturally-formed diamonds. Both CVD and HPHT diamonds can be cut into gems and various colors can be produced: clear white, yellow,
they never lost their their shine or color and are also cut and polished in the same way as mined diamond ,they have the same lustre and fire as the mined diamonds .
