Definition of diamond
Natural mineral consisting essentially of pure naturallycrystallised carbon in the isometric system, with a hardness
on the Moths scale of 10, a specific gravity of 3.52 and a refractive index of 2.42.
The stone’s name is derived from the Greek word adamas, which can be translated into unconquerable. This symbolic meaning lends itself well to the diamond’s historic commemoration of eternal love.
The earliest diamonds were found in India in 4th century BC, although the youngest of these deposits were formed 900 million years ago. At the time of their discovery, diamonds were valued because of their strength and brilliance, and for their ability to refract light and engrave metal. Diamonds were worn as adornments, used as cutting tools, served as a talisman to ward off evil, and were believed to provide protection in battle. In the Dark Ages, diamonds were also used as a medical aid and were thought to cure illness and heal wounds when ingested.
Surprisingly, diamonds share some common characteristics with coal. Both are composed of the most common substance on earth: carbon. What makes diamonds different is the way the carbon atoms are arranged and how the carbon is formed. Diamonds are created when carbon is subjected to the extremely high pressures and temperatures found at the earth’s lithosphere, which lies approximately 90-240 miles below the earth’s surface.About IDA
