Introducing Natural Amorphous Carbon Stone - Carbonado

Carbonado.vn is a leading supplier and distributor of natural amorphous carbonaceous stones in the Vietnamese market.

Natural amorphous carbonaceous stones (also known as carbonado) are mysterious gemstones, believed to originate from outer space, possessing a polycrystalline structure and containing up to 99% carbon. Unlike ordinary diamonds, they are only found in Brazil and the Central African Republic, possibly formed from meteorite impacts or in carbon-rich environments outside of Earth billions of years ago.

- Cosmic origin: The leading hypothesis suggests that naturally occurring amorphous carbonaceous rocks formed from giant meteorites (several kilometers in diameter) colliding with Earth from space.
  - Composition and structure: They contain approximately 99% carbon, a combination of millions of microscopic (polycrystalline) diamonds, resulting in exceptional hardness and a unique structure, completely different from natural diamonds formed deep within the earth. - Characteristics: Natural amorphous carbon is usually black or dark gray, opaque, with a distinct porosity and sheen.

- Lonsdaleite (Space Diamond): Another form is lonsdaleite, a hexagonal diamond formed when graphite-containing meteorites collide with Earth, capable of withstanding 58% more pressure than ordinary diamonds.
Natural amorphous carbon is not only a rare and precious gemstone but also an important subject of study regarding the history of the formation of the Solar System.
