How its artificial scarcity if it is possible to tell man made vs natre made diamond, they are two different this then! Purity of man made stuff is why it sucks, pure iron will rust the fuck away, u need add carbon and some metals to make good steel, same pure diamonds dont break light passing trough in such beautiful way as natural diamonds, and those impurities so far were not recreated by man.
