Did you know that a cubic zirconia has a greater chance of surviving a house fire than a diamond? Once you introduce enough heat or oxygen to a diamond, it disappears into a puff of carbon dioxide. Diamonds aren't rare either; there are warehouses full of diamonds, and the people running them don't sell them in order to keep the price up. The diamond manufacturers have an agreement to only release a certain number of diamonds a year. So, diamonds are neither "forever" nor rare. And this has been, my interesting fact for you all.
