About Diamonds
Modern scientific techniques have enabled scientists to date the age of formation of diamonds as being between 900million years to 3.3billion years ago. The geological conditions for the formation of this crystalline form of carbon require specifically high pressures and temperatures, an environment found in only two specific places on planet earth; the zone beneath the earth’s crustal plates in the upper parts of the mantle and in the rarer sites of meteorite strikes.
It takes millions and hundreds of millions of years for the results of this deep-seated volcanic activity to be exposed at the earth’s surface by the forces of erosion and deposition.
It wasn’t until the 4th and 3rd century BC when diamonds were first recorded as precious gemstones, holding qualities of strength, brilliance and hardness.
Today, diamonds are recognised as the ultimate gemstone, possessing unique ‘fire’ and aesthetic beauty. Because of its value as a highly traded commodity diamonds are graded according to The 4C’s ; Colour, Clarity, Cut and Carat.
