Diamond

Its name comes from the Greek adámas, which means the unalterable or indestructible.

Diamonds form under conditions of extreme pressure and temperature at depths between 140 and 190 km of the Earth's mantle, develop over 1 to 3.3 million years, and arrive close to the Earth's surface through deep volcanic eruptions.

Some of them are of extraterrestrial formation, arriving with the impact of asteroids, it is said that they come from supernova stars.

The diamond helps to transform us internally and reinforces unity.
