Diamonds are formed through extreme heat and pressure.

Under conditions of extreme heat and pressure, the carbon atoms crystallize in the earth’s mantle. As a result, diamonds form over billions of years. Thus, the most common way diamonds are formed is through volcano pipe eruptions shooting upward from the mantle.

The first diamonds were mined in India.

Diamonds were first mined in India around the 4th century BC. Furthermore, India is the only source of diamonds during ancient times. This is why India was the world’s leading source of diamonds, from ancient times until the year 1726. However, from the year 1726 to present, diamonds became more popular, leading to more and more countries joining the diamond rush hunt, taking away the throne from India as the leading diamond producer.
