Artificial diamonds are man-made materials which have the same chemical composition, crystal structure, optical properties and physical behavior as pure diamonds. Diamond varieties underneath excessive temperature and pressure conditions that exist only about 100 miles beneath the earth’s floor.
Diamond is a rare, naturally occurring mineral composed of carbon. This will doubtless be the greatest motivator for consumers to simply accept synthetic diamonds.
