Diamond Foundry Inc.

CarbonNeutral®-certified sustainable lab-grown diamonds

Our rough diamonds are produced carbon neutrally using renewable hydropower. We are proud to have Diamond Foundry Inc. as our partner: Since 2017, the company has been the first diamond producer worldwide to receive the recognized CarbonNeutral® certificate in compliance with strict guidelines.

I am proud to invest in Diamond Foundry Inc. – sustainably produced diamonds from America, whose extraction has no impact on people or the environment.

The CarbonNeutral® Certificate

We can guarantee a demonstrably sustainable production of our MANUFAKTURDIAMANTEN®.

When producing diamonds, Diamond Foundry follows the world-leading framework for carbon neutrality: the CarbonNeutral® Protocol. The rigorous certification involves an independent third-party assessment, for which data is continuously collected and analyzed. A report is then prepared to assess greenhouse gas emissions, documenting the carbon footprint. By accurately calculating greenhouse gas emissions, Diamond Foundry can take appropriate measures to manage these emissions during production.

NACHHALTIGKEIT TRIFFT AUF INNOVATION

Dank des äußerst energieeffizienten Herstellungsverfahrens der Diamond Foundry ist der MANUFAKTURDIAMANT® ein einzigartiger, nachweislich nachhaltiger und hochwertiger Diamant.

THE HOCHMODERNER FERTIGUNGSPROZESS

Zur Herstellung seiner Rohdiamanten nutzt Diamond Foundry die CVD-Technologie (Chemical Vapor Deposition, chemische Gasphasenabscheidung). Bei diesem Verfahren wird ein Plasma erzeugt, in dem sich Kohlenstoffatome frei an das Kristallgitter eines sogenannten „Diamantkeims” anlagern können, wodurch dieser Atom für Atom vergrößert wird, bis ein Diamant in Edelsteinqualität entsteht.

EMISSIONSFREIE PRODUKTION DURCH REINE WASSERKRAFT

Die Hightech-Produktionsstätte in Wenatchee, Washington, wird emissionsfrei betrieben. Die Diamond Foundry nutzt ausschließlich die Wasserkraft des Columbia River zur Herstellung der Rohdiamanten. Sie arbeitet eng mit den Verantwortlichen vor Ort zusammen, um sicherzustellen, dass auch für zukünftige Produktionserweiterungen zu 100 % erneuerbare Energien genutzt werden können.

MANUFAKTURDIAMANT® – the only truly sustainable alternative

“Lab-grown diamonds are only a genuine alternative if they are produced using renewable energy.” This statement from the Natural Diamond Council (NDC) report, published in early April 2023 to debunk myths and false claims in the diamond industry, underscores why our MANUFACTURED DIAMONDS® are a truly sustainable alternative.

Hydroelectricity is a reliable renewable energy source and can provide a constant supply of the high levels of energy required to grow synthetic diamonds. “In such cases, it can be said in good conscience that these lab-grown diamonds are more environmentally friendly than conventional lab-grown diamonds, where factories and machinery are heavily dependent on fossil fuels and non-renewable energy sources,” the NDC report confirms.

Fact 1: The CVD process has a higher environmental footprint. Sphera estimates that average emissions per polished carat produced using the CVD process in India can range between 260 kg CO2e and 612 kg CO2e. When using 100% renewable energy, Sphera estimates that this figure can rise to up to 17 kg CO2e per polished carat of a lab-grown diamond. With 0 kg/CO2e, Diamond Foundry’s emission-free production facility has an even lower environmental footprint than the figures estimated by Sphera.

Fact 2: Energy costs are one of the biggest burdens in diamond production. In the synthetic diamond market, different manufacturers use different reactors for their production processes, which vary in their energy efficiency. This also has an impact on CO2 emissions, ac
