1. Diamonds are the hardest materials that occur in nature
Diamonds are not only beautiful, but also extremely hard. With a hardness of 10 on the Mohs scale, they are harder than any other natural substance. This makes diamonds ideal for industrial applications such as grinding, drilling and cutting.
2. Diamonds in underground volcanoes
Diamonds are often associated with deep underground mines, but they are also found in diatremes, pipes that are created by volcanic eruptions. These eruptions bring diamonds to the earth's surface.
