It seems De Beers strategy is to clearly differentiate a man made stone vs a natural stone. This way a man made stone can't easily cannibalize the value of a natural stone's market price premium. The goal it seems is in-fact to maintain a premium with natural stones which is De Beers speciality. If they can't have all the revenues, De Beers want all the profits of the industry.
