A diamond forms under high temperature and pressure conditions that exist only about 100 miles beneath the earth’s surface. Diamond’s carbon atoms are bonded in essentially the same way in all directions. Another mineral, graphite, also contains only carbon, but its formation process and crystal structure are very different. Graphite is so soft that you can write with it, while diamond is so hard that you can only scratch it with another diamond. They are the hardest material on earth, 58 times harder than anything else in nature.
There is a difference in between hardness and toughness, hardness means the ability to resist against scratching, in the other hand toughness means the ability to absorb energy, with that being said don’t go back to your house grab a hammer and hit your diamond because it will break.
Diamond is the only gem made of a single element: It is typically about 99.95 percent carbon. The other 0.05 percent can include one or more trace elements, which are atoms that aren’t part of the diamond’s essential chemistry. Some trace elements can influence its color or crystal shape, and price. Come and visit any of our Express Pawn locations and see our diamond selections.
