Diamonds are formed under the surface of the earth under conditions of high temperature and pressure over billions of years. They come to when the layers of soil above them get eroded. Sapphires on the other hand are formed because of the metamorphosis of rocks which is very different from how diamonds are formed.

This is because diamonds disperse light to a great extent and emit a rainbow like flash. Sapphires do not exhibit as much dispersion as the diamonds. Diamonds are the hardest substance known to man and are therefore extremely durable and resistant to scratching. They score a 10 on the Moh’s hardness scale. Sapphires are not far behind and hard and durable but rank less when compared to the diamonds because they score a 9 on the Moh’s hardness scale.
