Jewelry designer and retailer Pandora announced today that it has added carbon footprint labelling for each of its lab-grown diamonds as part of the product information provided to consumers alongside traditional diamond criteria such as Cut, Color, Clarity and Carat.

According to Pandora, the new carbon footprint reporting is being introduced in response to increasing consumer expectations to sustainability, with the company also pledging to share its findings and methodology with other jewelry makers to drive greater transparency.

The company added that the new labelling will provide consumers with a new point of comparison and insight into the climate impact of their diamond jewelry, noting that lab grown diamonds have a carbon footprint roughly 90% below their mined counterparts.

Pandora CEO Berta de Pablos-Barbier said, “As consumers demand greater knowledge of how their products are made, transparency is becoming a defining force for brands. We are happy to share our learnings with others.”

Pandora stopped using mined diamonds in 2021 and is now only using lab-grown diamonds made with 100% renewable energy, which it noted are chemically, optically, thermally and physically identical to mined diamonds. The company also announced in 2024 that it completed the transition to using 100% recycled silver and gold in its jewelry.

The carbon footprint data provided by the company covers all emissions from the diamond crafting process, from producing raw materials to cutting and polishing the diamond. Pandora said that the carbon footprints of the diamonds have been calculated by external life-cycle assessment experts and published in a study verified by EY.

de Pablos-Barbier said, “We believe the future is about making diamonds more accessible while giving customers clarity on what they’re buying. We craft our jewellery with sustainability in mind and by introducing the 5th C, we’re empowering consumers to make informed choices.”
