![]() For context, 148 million carats were mined in 2018. “It takes an entire factor more energy to extract an underground diamond from Earth than it takes to create one above ground. On top of this, the energy used in mining is generally dirty diesel versus renewable energy in our above-the-ground production,” says a blog post on their website.Īn estimated 250 tonnes of earth is shifted for every single carat of diamond. However, the latter says that it is certified as carbon neutral by the third party Natural Capital Partners and uses only renewable energy.įigures published by Diamond Foundry suggest that the total environmental footprint of mined diamonds is much higher than lab diamonds. Companies including Ada Diamonds and the Leonardo DiCaprio backed Diamond Foundry in the US were among them. However, some lab diamond companies have been warned by the Federal Trade Commission in the US to be careful when presenting themselves as “eco-friendly” without evidence to substantiate these claims. It’s worth noting that the DPA represents seven of the world’s largest diamond miners, including De Beers, Alrosa and Rio Tinto. One report on the topic, commissioned by the Diamond Producers Association, suggests that the greenhouse gas emissions produced mining natural diamonds is three times less than those created when growing diamonds in a lab. A distinct lack of transparency makes it difficult to source accurate data to compare the carbon footprints of mined and lab diamonds, but the energy needed to produce a lab diamond is significant. ![]() The growth is expected to continue as more jewellers start to sell lab diamonds and more labs are launched.īut lab diamonds are not without fault. Young diamond-buyers are drawn to them by price, transparency and for environmental reasons, with this segment of the market increasing by between 15% and 20% annually, according to the AWDC report.

It has meant growing competition between lab diamond and mined diamond companies. The technology behind lab diamonds has made crucial advances in recent years, allowing companies to grow higher quality diamonds more rapidly and more cheaply. Most were formed between 1bn and 3bn years ago at a time when our planet was hotter than it is today. Naturally occurring diamonds are forged in the crushing pressure and immense heat of the Earth’s mantle around 100 miles underground. The quest to make a material harder than diamondsįirst up, a lab-grown diamond is a diamond: chemically, physically and optically identical to a mined diamond.Can we heat buildings without fossil fuels?.So what are lab grown diamonds, and are they really a more sustainable alternative to traditional mined diamonds? ![]() ( Read more about the rise of guilt free gems.) Millennials and now Generation Z – who together are the main purchasers of diamonds for engagement rings – are moving away from conventional diamonds, with nearly 70% of millennials considering buying a lab grown alternative. Nauhaus’s father owns a diamond jewellery shop, and her grandfather worked for De Beers, making his career in diamonds after World War Two.ĭespite their illustrious family histories in the trade, Neuhaus and Warch chose to break away from conventional diamonds because of the environmental and humanitarian toll of extracting them. Based in Antwerp, the capital of the world’s diamond business, both she and her co-founder Jessica Warch grew up in diamond families.
