Reply to comment by Worst_username_eu in Scientists have analyzed the specific labor costs for producing a 1 carat diamond in mines and through artificial synthesis. The work of human turned out to be more effective: 26 minutes versus 2-3.5 hours. by Skoltech_
The measurement is "carats per hour" not "diamonds per hour".
So one 5 carat diamond pulled out of the ground and five 1 carat diamonds pulled out of the machine would be equal production in this study.
