Madestones, the well-established European producer and distributor of lab-grown diamonds, is proud to announce a pioneering achievement in the diamond industry. The company has successfully obtained the Golden CO2 Neutral label certification for the full life cycle of its diamonds, setting a new benchmark for sustainability in the lab-grown diamond sector.
While many companies in the industry focus solely on the renewable energy required for the production of lab-grown diamonds, Madestones recognized that this approach alone is not enough to make a meaningful impact on climate change. Driven by a commitment to genuine sustainability, Madestones embarked on a rigorous journey seven months ago to ensure that every aspect of its diamond supply chain meets the highest environmental standards.

Madestones collaborated with South Pole, a leading climate solutions provider, to conduct a comprehensive audit of its entire supply chain. This thorough assessment covered every stage of the diamond life cycle, from the purchase of natural gases used in production, to cutting, certification, multiple transportation phases, and the operations of Madestones’ offices. In essence, the company examined the environmental impact of its diamonds from the very beginning until they reach the offices of their customers.
The result is a major milestone for Madestones and the lab-grown diamond industry as a whole. Madestones is now the first in its sector to achieve full life cycle CO2 Neutral certification, a testament to the company’s dedication to sustainability and real climate action.
This certification was awarded following a stringent five-step process. Madestones began by analysing its current environmental impact, including a full life cycle assessment of its main product. The company then set targeted goals to reduce its carbon footprint and supported impactful climate initiatives to offset any remaining emissions. The independent auditor Vinçotte, ensuring the credibility and rigor of the achievement, validated the final certification.

“Our commitment to sustainability goes beyond the standard industry practices,” said Thierry Silber, CEO of Madestones. “We took on the challenge to not only focus on the production phase but to ensure that every step in our diamonds’ journey is environmentally responsible. This certification is a testament to our dedication to true climate action.”
This accomplishment not only reinforces Madestones’ leadership in the lab-grown diamond sector but also sets a new standard for sustainability in the industry. As consumers increasingly seek environmentally responsible products, Madestones’ commitment to a fully carbon-neutral supply chain demonstrates the company’s dedication to meeting and exceeding these expectations.
