(jckonline.com) - For the last few weeks, I have been researching the environmental impact of lab-grown versus mined diamonds for a future blog and article in JCK. And one of the people who I wanted to talk to was Dr. Saleem Ali. Ali, an environmental planner and a professor of energy and the environment at the University of Delaware, is the only academic, to my knowledge, who has studied it. His 2011 working paper on the issue is available here. It was eventually updated and published in the Journal of Bioeconomics in 2017.
