What is a diamond?
Over a billion years ago, deep beneath the Earth's surface, carbon atoms bonded tightly under high temperatures and extreme pressure, resulting in the world's hardest natural mineral: diamond.
Hidden for millions of years, diamonds only reached the Earth's surface after volcanic activity transported them upward in magma. Then, in the 4th Century BC, the first diamonds were found in India. Today, as they have been for centuries, diamonds are one of the most beautiful and coveted objects on Earth.
