I think people will keep buying diamond jewelry with natural because it the product is sold as real/natural diamonds. Prestige is important for the high-end market and most of the price will be markup anyway. (Well diamonds are nearly all markup anyway).

Tiffany's isn't suddenly going to be cheaper.

Or even the other way around: with the economies of scale created by industrial use cases removed, mining diamonds just for jewelry could get more expensive.
