It's all just a crystalline form of carbon.
Regardless of how it was made, one is just as much "forever" as the other. The real major difference is in the labor practices being used.
De Beers had a good run as a cartel but as they say, "the jig is up"
The entire point of a diamond is that it’s expensive. People buy them for status. Otherwise there are lots of gems that are much more prettier, but they are not as expensive. It’s like saying people will stop buying branded clothes because unbranded clothes have the same or even a higher quality for a fraction of the price. Kinda misses the point.
People buy inferior, counterfeit merchandise all the time because they can't tell the difference.
But there is nothing inferior or counterfeit about a manmade diamond. It is *exactly* the same material as a natural one.
Yes, you can buy a man-made diamond the same you can buy counterfeit branded clothes. That only shows that you’re tasteless and that you can’t afford the real thing.
