Blue Diamond
Found in - South Africa, Sierra Leone, Nambia, Angola, Australia, Canada, Russia, & USA. Sir William Crookes, a gem connoisseur as well as a chemist and physicist, was the first to discover radiation's effects on diamond color when in 1904 he conducted a series of experiments using radium salts. Diamonds enveloped in radium salt slowly turned a dark green; this color was found to be localized in blotchy patches, and it did not penetrate past the surface of the stone. The emission of alpha particles by the radium was responsible. Unfortunately radium treatment also left the diamond strongly radioactive, to the point of being unwearable.[3] A diamond octahedron so treated was donated by Crookes to the British Museum in 1914, where it remains today: it has lost neither its color nor radioactivity. Presently diamonds are safely irradiated in four ways: proton and deuteron bombardment via cyclotrons; gamma ray bombardment via exposure to cobalt-60; neutron bombardment via the piles of nuclear reactors; and electron bombardment via Van de Graaff generators. These high-energy particles physically alter the diamond's crystal lattice, knocking carbon atoms out of place and producing color centers. Irradiated diamonds are all some shade of green, black, or blue after treatment, but most are annealed to further modify their color into bright shades of yellow, orange, brown, or pink. The annealing process increases the mobility of individual carbon atoms, allowing some of the lattice defects created during irradiation to be corrected. The final color is dependent on the diamond's composition and the temperature and length of annealing. History - Diamond is the hardest mineral on earth, with luster and fire, makeing it the most highly prized gem. The most popular stones are colorless, but are also found in colors ranging from yellow and brown to green, blue, pink, red,(most rare) grey, and black, depending on the impurity present. Diamond forms at high temperatures at a depth of 50 miles or more under the earth. They are graded by cut, clarity, and carat. The name derived from the Greek word "adamas" meaning unconquerable. Diamonds are usually found in gravel or Kimberlite. They were first found first in India and later Brazil, then South Africa, and Australia. The only location of diamonds in the U.S. is in Murfeesboro Arkansas. Diamonds are a pure carbon composition, as are coal and graphite, and can only be cut by another diamond. An average of over 275 tons of rock have to be mined to find one was the only source, at Golconda, which has been mined since the 3rd millennium. The Kolninoor or mountain of light diamond found there is believed to give the owner world domination and is now property of the British Crown. Metaphysical - It was thought that a diamond held in the mouth of a liar would help him speak the truth. Diamonds are also thought to soften anger, and strengthen love and harmony, which is why it is commonly used for wedding and engagement rings.
