Formation and Composition of Carbonado
- Carbonado is a type of diamond composed of microscopic diamond crystals.
- It is formed through a high-pressure and high-temperature process.
- Carbonado contains trace amounts of nitrogen and hydrogen.
- The formation of carbonado is believed to have occurred in an interstellar environment.
- It is theorized that carbonado may have originated from carbon-rich cosmic dust.
Physical and Chemical Properties of Carbonado
- Carbonado is the toughest form of natural diamond.
- It has a porous and irregular structure.
- The color of carbonado ranges from black to gray.
- Carbonado has a high density and is heavier than regular diamonds.
- It exhibits unique optical properties, including strong luminescence.
Extraterrestrial Origin of Carbonado
