Laser

Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. A powerful, coherent, straight-line beam of light, very narrow in diameter which, when strong enough, can be used to cut through solid substances. Lasers can be strong enough to cut through diamond and is more precise and much safer than previous hand sawing and cleaving techniques. Lasers are also sometimes used to "clean out" dark inclusions in diamonds. Laserscan also be used to place microscopic inscriptions and identification marks on diamonds and other gemstones.
