Diamonds form between 75 and 120 miles below the earth’s surface. According to geologists, the first recovery of diamonds was around 2.5 billion years ago and the most recent was 45 million years ago.
Diamonds have been a source of fascination for centuries. They are the hardest, the most imperishable, and the brilliant of all precious stones. The word diamond comes from the Greek word adamas, meaning unconquerable.
A diamond is a transparent gem made of carbon, one of the earth’s most common elements. The formation of diamonds began very early in the earth’s history, when the condensation of solid matter into a sphere caused the center of the planet to become subjected to incredible extremes of temperatures and pressures.
