Diamonds is the worlds' hardest mineral. They are transparent through a large range of wavelengths and are commonly known as a girl's best friend. Diamonds come in many colors, such as yellows, browns, grays, and also white, blue, black, reddish, greenish and colorless. Diamonds are the best conductors of heat and have a melting point of 3820 Kelvin. The crystal system/structure is isometric and forms in such shapes as cubes and octahedrons, twinning is also seen. Depending on how perfect the lattice of a diamond is, will change the price of a diamond. The price can range from hundreds of dollars to hundreds of thousands of dollars.
The index of refraction of a substance is defined as n = c/v where n is the index of refraction, c is the speed of light and v is the velocity of light through the material. This determines the amount of refraction that occurs when light goes from a vacuum into the material. The index of refraction of a diamond is 2.4175, an exceptionally large number. There are no units for index of refraction.
