Researchers at the Carnegie Institution have been successfully creating large diamonds using chemical vapor deposition (CVD) for a few years now. Now they’ve announced a new technique for improving the color and clarity of their diamonds. A special annealing process turns the yellow-brown created stones colorless and pink. The large size and transparency resulting from these methods will enable the creation of diamonds for high-pressure situation and optical applications. They also mention the possibility of using these diamonds in the future as storage devices for quantum computing.
