Lab Grown Diamonds (Lab cultured, man made diamonds)
Lab grown diamonds--unlike CZ and other simulants--are REAL diamonds.
Lab grown diamonds have nearly the same physical and optical properties of natural diamonds. It is virtually impossible to distinguish with the naked eye and requires special equipment to identify a lab grown diamond. They are just as hard, and they are available in a range of colors and qualities. Just like natural diamonds, they can have an excellent cut—and, therefore, excellent fire, brightness and scintillation—or they can have a poor cut or anything in between just like with earth mined diamonds. It all depends on the quality of the diamond and the skill of the cutter.
While natural diamonds may take billions of years to form, lab grown diamonds can be grown in a matter of weeks! It is quite impressive how technology has advanced and this is a relatively new breakthrough that is disrupting the industry and worth looking into.
Lab grown diamonds are produced in a variety of ways. The supplier we have chosen for lab grown diamond specializes in using the Chemical Vapor Deposition (CVD) process will be described here:
With this newer technique, synthetic diamonds are grown in an apparatus that uses moderate temperatures and very low pressures in a vacuum chamber. The CVD process involves heating a mixture of a hydrocarbon gas (such as methane) and hydrogen, which releases carbon atoms that then settle onto the cooler, typically square-shaped seed plate of natural or, more likely, synthetic diamond. This results in a square-shaped, tabular synthetic diamond crystal. Once the crystals are made they are fashioned the same way that a natural diamond is fashioned to bring the sparkle to life. CVD diamonds and Natural Diamonds look exactly the same next to another and even a professional jeweler could not tell the difference since both stones share the same attributes and chemical composition. In order to tell one from the other it is necessary special laboratory machines created for this use. CVD diamonds are priced 30% to 40% lesser than natural diamonds and just like Natural Diamonds they are priced depending on their 4Cs characteristics: Color, Clarity, Carat and Cut.
