Yup, exactly. The man-made diamond industry should just counter by talking up how they can make perfectly "pure" diamonds with zero imperfections in color or clarity, superior in quality to mined diamonds, and with no human lives lost. Just keep drilling that point home in all their sales and PR until it changes the dynamic. I'm sure the millennials will be receptive to that - cheap, better, not immoral.
That would be a marketing battle, which is often won by the side with the biggest marketing budget, probably the well established natural diamond industry.
Besides, I personally feel that "lab grown diamonds" have more weak (marketing) points than "natural, made by stars, millennial diamonds". Could be wrong though.
