Don’t shoot for perfect crystal and gem-quality diamonds. Synthetic diamonds produced by high-temperature and high-pressure methods are yellow because of nitrogen-containing impurities. At the same time, because of the limitation of production methods, they will wrap metal particles. Single crystals do not mean regular hexahedrons and octahedrons. Mind if you don’t shoot!
