2. Diamonds are indestructible and last forever.
Not exactly true. The idea of a diamond lasting “forever” is the result of the same marketing campaign that sold the idea of a diamond ring as a marriage token. A diamond can certainly last for multiple generations–in fact, most diamonds found today are over one billion years old. However, to say that a diamond is forever would imply that it is an indestructible object. Diamonds are naturally hard substances and are able to withstand various forms of scratching. However, hardness is slightly different than toughness and a diamond is not the strongest form of material known to man. Furthermore, a diamond can still be chipped, broken or damaged if it is treated in a haphazard way.
