Our lab created diamonds are grown from the tiny carbon seeds of pre-existing diamonds. Advanced technology – either extreme pressure and heat or a special deposition process known as CVD – mimics the natural method of diamond formation. Some lab diamonds grown through deposition may also undergo pressure and heat treatment after they are grown. Lab grown fancy colored diamonds are formed when small amounts of specific trace elements are present during the growth phase of the diamond, just like in nature. In both white and fancy colored lab diamonds, the exact composition of trace elements may differ from their natural diamond counterparts. Lab diamonds can only be distinguished from natural diamonds using specialized equipment that can detect the minor differences in trace elements and crystal growth.
