Can you tell me what is the difference between a man-made diamond and a natural diamond?

The main difference between a man-made diamond and a natural diamond is in their origin. Man-made diamonds are made from carbon, which can be found in nature, but they are usually grown in a lab under high pressure and temperature conditions. Natural diamonds are formed deep within the Earth over millions of years and contain impurities that make them more rare than man-made diamonds.
