Composition
Diamonds are composed entirely of pressurized and superheated carbon. They are the second most stable form of carbon found in nature.
Hardness
The diamond is the hardest known material that exists in the natural world. Because of this, it is often used in cutting tools in industrial settings.
Gemstones
Diamonds are often cut and polished to create beautiful gemstones. These are used to make some of the most sought after jewelry in the world and are traded in retail settings more than other precious minerals.
Impurities
Most natural diamonds contain impurities that can affect their color. For example, those that contain boron are a blue color and also a type of diamond that can conduct electricity.
Controversy
Diamonds mined in certain parts of Africa have started a harsh controversy. Rebel groups in the area that took control of diamond mines are known to treat their workers poorly and the diamonds are often used to fund violent, revolutionary groups.
