Sure, but part of the point of the article was that the "created" diamonds could be made that are literally indistinguishable from those found in the ground. Seems like that has the potential to disrupt the diamond cartel's stranglehold on supply.
In a practical sense, cubic zirconium stones are indistinguishable from diamonds as well. Unless someone breaks out a diamond tester, no one will be able to see the difference. Yet consumers continue to purchase real diamonds.
If a much less expensive synthetic diamond were to enter the marketplace, it would have the same problem as a CZ. Anyone who purchases one would either have to be honest about their purchase, and therein lose the social status benefit, or lie about their purchase, in which case they might as well have bought a CZ.
Perhaps you're right. But I bet a lot more people would be willing to lie about how "real" their diamond is if there was no way anyone could prove otherwise.
