If I was shopping for a near flawless diamond engagement ring and someone was offering me the lab-made version.

I think I’d be quite swayed towards the lab ones knowing that there were engineers who used them for industrial use and found them exactly the same.

Also being much cheaper, I’d likely spend money towards getting a better grade lab-grown diamond than I could afford with a mined diamond.

If I was the lab-grown industry I’d also be actively attempting to shift the narrative around the term real, and say ones mined one is lab made, both are real. But that’s its own fight I’m sure.
