You read it right! A team from the United States has created an improvement to synthetic diamonds; they have no limit to size!
The diamonds are created by chemical vapor deposition ( or simply CVD). This is where carbon atoms are deposited on a surface which, in the end, produced diamond crystals.
This produces diamond growth, however, the impurities from the gas will give the diamonds a brownish tint. The impurities can be treated by annealing, which is a high-pressure, high temperature treatment.
The team was led by Russel Hemley, from the Carnegie Institute of Washington.
