What properties make the diamond useful?
The gem quality stones capture our imagination like nothing else can, but it is the industrial diamond that is arguably the most useful application for diamonds. A link can be found below. We often consider that the beauty and desirability of the diamond is what makes it valuable. But the diamond is the hardest naturally occurring substance.

Fine bits of diamond are used to give a gem stone the characteristic shape and finish we see when this allotrope of carbon is used in jewelry. Of all diamonds mined, about 80% are industrial diamonds and only 20% qualify as gem-quality. As well, most diamonds mined are about the size of a pea.
