Ho et al. have grown single-crystal CVD diamond gemstones 6.7 mm in diameter and 12 mm high . The crystals were intended primarily for use in diamond anvil cells, but the same technology can be used to make commercial gems. Companies such as Apollo Diamond are beginning to exploit these advances for growing commercial gemstones.
