We have started a series of brief articles under the title ‘Do you know diamonds?’ We hope they contain something of interest for you.

1. Diamonds are entrusted to us by Mother Nature

Diamonds were created by the Earth, just as air and water. Two billion years into the Earth’s 4.6 billion year history, diamond crystals started to form by the actions of incredibly high pressure and temperature approximately 150 kilometers below the Earth’s crust. Later, volcanic activity threw kimberlite and lamproite rocks, and the diamonds encased in them, to the surface of the Earth. And these deposits are the primary source of diamonds. Nature also has a hand in giving us secondary deposits of diamonds. Through erosion, she takes the diamonds out of these rocks over huge stretches of time, patiently breaking down the volcanic rocks holding the diamonds and depositing the gems in the banks of rivers, or sometimes sweeping them down to the shoreline, to be collected by sieve. Diamonds are not as abundant as air or water, but still they are a creation of Mother Nature. Humans polish the very rare transparent diamond rough and pass the resulting pieces down through the ages with their incomparable and unique beauty to be worn and enjoyed for generations. In this way, diamonds are entrusted to us by Mother Nature.
