This is how old diamonds really are
One of the most popular diamonds slogans is a diamond is forever. That phrase was coined in order to help develop the idea of diamonds signifying eternal love--a symbolism that works very well when you consider just how long diamonds can last. Because they are the hardest natural substance, they are virtually indestructible and can go on existing indefinitely. That longevity can be seen by looking towards the past--the average diamond is well over one billion years old! In fact, many diamonds on the market exceed two and even three billion years--a number so large, it encompasses over 75% of the earths total lifespan!
