Title is misleading. “1 carat of diamonds” is not the same as “1 carat diamond” as stated. Also, huge difference if mining counts the dust and industrial only diamonds they collect, and the lab is growing near perfect near colorless diamonds.

It’s like saying Maybach’s can only be built 1 per week, but Honda can crank out Accords at 1000 per week, so Honda manufacturing must be “better”.
