You understand that lab made diamonds are chemically identical, and have identical properties, to mined diamonds? And are orders of magnitude cheaper to create. Does that instantly make this viable? No. Does it mean that the fact that diamonds, which are themselves kept artificially priced high by cartels such as De Beers, will be the most cost prohibitive part of improving longevity and speed, and reducing cost in PCM? Seems unlikely to me. But who knows. Don't get caught up on the fact that it's diamond though.
