Tesoros de la Tierra: los diamantes

Diamonds, known for their unbreakable nature, are formed from carbon under high pressure and temperature deep in the earth's mantle over billions of years. They reach the surface through volcanic eruptions. Diamonds have a unique lattice structure, making them rigid and shiny, often free of impurities. Contamination with elements like nitrogen and boron can change their color. Diamonds are carved into various shapes and are valued based on carat, cut, color, and clarity. While famous as gemstones, 80% of mined diamonds are used industrially for cutting, grinding, and polishing due to their durability and thermal conductivity.
