When natural diamonds are found in the earth, before they are cut and polished, they are called rough diamonds and still have their outer ‘skin’. They can be discovered in a variety of shapes from cubes to octahedrons (imagine two pyramids joined together at the base). All started life deep within the earth’s mantle between 720 million to 3.5 billion years ago, created under extreme pressure and high temperatures.
The exact conditions of their creation, as well as those they experienced during their long journey to the earth’s surface through volcanic activity, shape their unique characters and colours. For example, pressure can distort their atomic lattice to create a pink rough diamond, or when saturated with nitrogen, they appear yellow.
Rough diamonds were first discovered in India almost 2,500 years ago and many ancient civilisations have been captivated by their appearance and touchable texture. Diamonds were a symbol of power long before they became a symbol of love, and were often worn by Kings and Princes going into battle as talismans.
