Introduction to Diamonds
Diamonds are one of the most precious and sought - after gemstones in the world. Composed of pure carbon, they are formed under extremely high pressure and temperature deep within the Earth's mantle. Their unique physical properties, such as high hardness (being the hardest known natural material on the Mohs scale), excellent refractive index, and high dispersion, give them a brilliant sparkle that has captivated humans for centuries.
Diamonds are not only used in jewelry, including engagement rings, necklaces, and earrings, but also have industrial applications. In the industrial sector, their hardness makes them ideal for cutting, grinding, and drilling tools.
