The market has changed drastically since some Chinese factories start mass producing synthetic diamonds around 2019.

Currently in the end market the price is $200~300 for a 1CT synthesized one, and the quality are simply better all around. The only way to distinguish natural ones is to track from the start where each is mined and processed, which is a bit absurd.

Many of these factories were associated with drill head industry and the like until they found the jewelry market is much more profitable and got the trick to mass-produce them. If they are willing to compete a bit the price might even go lower.
