Through the use of ADT (amorphous diamond technology) technology man-made diamond crystals are infused into simulated crystals to create a diamond top that is made of pure carbon SP3 bonds.This adds a thick layer of organized lattice on the surface of these stones and allows them to convey a look and feel that approximates authentic diamonds. In fact, in their optical and physical properties they are the closest that synthetic diamonds come to natural stones. The upper layer of carbon lends a sparkle to these stones that makes them stand out amongst the other Man Made stones.
