Answer:
I dissagree, diamonds are not forever. Some may say that they are, but nothing is forever. Diamonds can be damaged with other diamonds. Diamonds can't be destroyed by anything other than another diamond. Others may beleive that Diamonds are forever because they do not have many things that can damage them, but they do still have one thing that can. Which like I said before, is diamond.
