Artificial diamonds threaten natural diamonds!

A team of American researchers has developed a technology that makes cheap, high-quality and cheap-quality diamonds.

Researchers at the Carnegie Institution of Washington have created diamond crystals by depositing chemical vapor (CVD) with carbon atoms in the gas.

The CVD process makes diamonds grow rapidly, however, if the gas is impure, the diamond will have a slightly brownish color.

Researchers say the effect can be removed by treating it at high temperatures and high pressures (also known as tempering). However, the process of refining is only suitable for small diamonds larger than 34 carats and about 1 cm wide.

According to researchers, the technology can be easily applied to any laboratory that needs it.

Improving the quality of artificial diamonds is threatening the natural diamond market. Every year about 20 tons of natural diamonds are mined, while up to 600 tons of synthetic diamonds are made available for industrial applications.
