That’s a silly way to look at it. Surely people can realize that something made through natural processes has more of an appeal than something made in a factory?

That said, most of the gems I’ve purchased in my life have been lab grown.

I'd argue that most people appear to prefer manufactured things these days.

No one's wearing clothes their mothers' spun because mothers' see that their children prefer the "higher quality" that is manufactured in factories.

Few choose to spend their time engaged in walking about in nature and choose instead to gaze endlessly at their factory built device that provides them content ground out in other sorts of factories. (content farms etc).

Something made in nature can be more appealing, but it seems to me that the modern preference is not at all for natural things. Hell, even in the diamonds we're talking about. No one's proposing with a natural diamond. People propose with carefully curated, carefully manipulated, and carefully presented diamonds. There's nothing natural about it, really.
