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 Adams, 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 pressure.
It was these conditions that caused deposits of carbon to begin to crystalline deep in the earth. As the earth’s surface cooled, volcanic activity forced streams of manna (liquid rock) to the surface, carrying with it the diamond crystals. Later, the diamond-bearing rock hardened, encasing the diamonds in vertical volcanic “pipes”
