They say "diamonds are forever," but what they really mean is that diamonds are a never-ending sign of love. What element makes up this precious gemstone?

Pure diamonds are entirely made up of carbon while other lower-quality diamonds have some chemical impurities such as nitrogen in them. The atoms of a diamond are arranged in a stunning crystal structure called "diamond cubic".
