Diamonds are forever?One of our super-bosses today, used the phrase “because diamonds last forever…” Is this true? I don’t think so. Diamond is said to be the hardest known substance naturally occurring, but that doesn’t mean that it is indestructible. They will shatter if treated roughly because they are brittle. They will also burn (with some difficulty) and dissolve in some substances. For this reason I suspect that they do also naturally decay by oxidation but very slowly due to the tight molecular bonds.
It is also to be noted that diamond is not the rareest or most expensive of the gem stones. Good sapphires, emeralds, garnets and rubies are much less common and fetch higher prices; particularly now that sythetic diamonds are getting to be so good.

if you get a diamond hot enfough it will melt
if just before it melts you drop it into liquid oxygon it will burn
very well
and nothing will remain other than carbon dioxide
ergo diamonds are not forever
