Diamond Foundry

Denim and diamonds might just be the ultimate high-low mix. And if indigo with a hint of sparkle strikes one’s fancy, you’re in good company with Tejidos Royo, a sustainable denim mill based in Spain that recently inked a deal with Gap Inc.’s Banana Republic brand to collaborate on sustainable denim initiatives using a waterless, indigo-foam dyeing technique. The mill’s exclusive new process, called Dry Indigo, can reduce water usage by up to 99 percent, while using 89 percent less chemicals, reducing energy usage by 65 percent and eliminating water discharge when compared to traditional indigo processes, according to the firm. Banana Republic’s denim with Dry Indigo will be available through a special collection for men and women in spring 2020, the company said.

Gap Inc.’s executive vice president of global sourcing, Christophe Roussel, said, “Leveraging this revolutionary new dyeing process directly supports Gap Inc.’s manufacturing goal to conserve 10 billion liters of water by the end of 2020, as well as Banana Republic’s recently unveiled sustainability goals to produce eco-friendly denim, reduce water impact and promote cleaner chemistry. Tejidos Royo is a trusted partner and true pioneer in sustainable innovation. We are thrilled to work with them on this exciting new venture and have no doubt that this will change the future of denim manufacturing.”

And pairing that denim with precious stones from Diamond Foundry, an ethical created diamonds company based in San Francisco, creates a sparkling — and sustainable — ensemble. Diamond Foundry uses proprietary solar technology to sustainably grow diamonds that possess an identical composition to natural mined diamonds, enabling a “morally pure” process that impressively and miraculously reduces its carbon footprint to zero. Through its founding team of MIT, Stanford and Princeton engineers that had previously developed technologies in the solar power sector, together they realized that “the energy of the sun could also be used to make a better diamond, atom by atom,” according to the brand.

Ye-Hui Goldenson, director of public relations and communications, Diamond Foundry, told WWD, “We launched in 2015 and [the company] has just grown exponentially. I think being sustainable has always been a really big part of the goal of our company, and not just making diamonds, but how do we keep doing things smarter and better and through a process that’s also great for the environment? It’s an industry that needed a lot of change, and I think everyone felt very passionately about how we could really make a difference in the diamond market.”
