Pandora is introducing carbon footprint labeling for its lab-grown diamond collection, claiming a 90% lower impact compared to mined diamonds. The company is using consultant reports to back these sustainability assertions, comparing the footprint of its diamonds to that of a pair of jeans. Critics argue the data relies on an older 2019 study and ignore the socioeconomic impact on diamond-producing nations. The move highlights the ongoing tension in carbon accounting within the jewelry industry as brands attempt to quantify environmental advantages.
