As can be seen in the figure above, artisanal diamonds have the highest true cost. The true cost of diamond combines the impacts of producing rough diamonds and the processing step. All figures are in USD per carat of polished diamond for use in jewellery.

|Description:||True Price calculated the true cost of 1 carat of polished diamond in three systems: large-scale mining, artisanal mining, and laboratory-grown diamonds. We also assessed ways for the sector to move forward. For example, reducing coal for energy use in diamond synthesis can save USD ~780m/year in environmental impacts. Similarly, reducing underpayment in the polishing industry can prevent USD ~35m/year. Understanding pathways for improvement can contribute to significant change in the diamond sector in the years to come|
