For many centuries people have been convinced that diamonds are so durable that they cannot be destroyed. Diamonds are truly recognized as the hardest material with a hardness of 10 on the Mohs scale. But even they are not immune to damage. Diamonds can be scratched by other diamonds or cracked by a strong blow. In addition, diamonds can crack during the process of cutting or inserting the stone into the jewelry.

Surprisingly, the same rubies and sapphires that are rated significantly lower on the Mohs scale are actually less destructible. Also, diamonds burn because they are pure carbon. True, for this you need to heat the stone to 1000 degrees. It is this temperature that will turn the diamond into carbon dioxide - just like in a soda bottle.
