Origin of the Diamond - Geographically

We’d like to share our passion and expertise for diamonds with you, which is why we’ve created the Blesq diamonds blog – read on for gripping tales and exciting news about the most precious gemstone on Earth.

It takes carbon, extreme heat and high pressure, to create a small, unique specimen like a diamond. There are several circumstances that cause these three factors to occur together. Asteroid impacts generate a tremendous amount of pressure and heat causing diamonds to form. The Barringer Crater in Arizona, and the Popigai crater in northern Siberia, are such examples of locations where diamonds were discovered.

Even beneath stable tectonic plates, diamonds have formed over millions of years and are transported by volcanic activity in so-called lava tubes to the surface. The different inclusions in diamonds reveal that many originated from shifts in oceanic and tectonic plates.

These diamonds contain, for example, traces of seawater and other minerals from the oceanic plate. This suggests that an oceanic plate has slid underneath a tectonic plate, pushing the carbon deeper. In this way over millions of years, under extreme heat and pressure, diamonds have emerged.

At Blesq Diamonds, look around for a small, unique, fire from within the earth.
