Diamond comes from the Greek word “adamas” meaning invincible. It is crystallized carbon, the only gem composed of a single element. It is the hardest natural material known to man and the third-hardest known material after aggregated diamond nanorods and ultrahard fullerite. Its hardness and high dispersion of light make it useful for industrial applications and jewelry.
The most popular diamonds are traditionally colorless, but they can also be found in yellow and brown colors. Although much rarer, diamonds known as “fancies” also come in blue, red, pink, green, orange and black. They make excellent abrasives because they can be scratched only by other diamonds, Borazon, ultrahard fullerite, or aggregated diamond nanorods, which also means they hold a polish extremely well and retain their lustre. On Mohs’ scale of hardness, diamond is the world’s hardest substance at 10. 1 is the softest and 10 is the hardest.
People before already used diamonds as their gift to other noble people. The first recorded diamond engagement ring was on 1477, when Archduke Maximillian gave his betrothed a ring set with a diamond as a love token.
It is the birthstone of a person born under the zodiac sign of Aries (Ram) from March 21 - April 19. It is said that diamond has a healing ability. Diamond is a great assistance for all brain diseases and strengthen the owner's memory. Diamonds give faith, purity, life, joy, innocence and repentance. It is an antidote to poison and is capable of detecting poison by exhibiting a moisture or perspiration on its surface. Supposedly, the higher quality the diamond, the better it supports these qualities.
