Also called cultured diamonds, synthetic diamonds are man-made stones with the same composition or molecular structure as their natural counterparts. Both are crystallised carbons. The difference is that synthetics can take as little as a few days (up to several months) to make in a laboratory, whereas natural diamonds can take millions of years to form underground.
