FAQ

We answer all questions about production and our quality promise, order processing and delivery and the company history of Nevermined lab-grown diamonds.


General information

Nevermined stands for sustainable, transparent and conflict-free diamond production. As one of the first manufacturers of lab-grown diamonds in Germany, we are committed to ethical and environmental standards to help create a sustainable future for the jewellery industry. 

Environmentally-friendly production with renewable energies and fair working conditions are a matter of course for us and are part of our corporate culture. We are aware that 100% perfection is not achievable, but we are constantly striving to get as close as possible to a sustainable future. 

Our corporate values are based on responsibility towards our employees, the environment and future generations, and we strive to be a role model for sustainable business.

Nevermined was founded in 2021 to offer a sustainable alternative to conventional and conflict-ridden diamond production. Our founders, Christine Marhofer and Michael Marhofer, firmly believe that sustainability and luxury can go hand in hand and set themselves the task of revolutionising diamond production.
Our factory is located in Essen, Germany, in the heart of the Ruhr region. This is where we produce lab-grown diamonds of maximum clarity and quality under fair and transparent conditions.

Our name Nevermined is a clear statement: our diamonds do not come from mines, but are grown in Germany under the highest scientific standards in the laboratory – without the mining of natural diamond deposits. 

A common misconception is that raw materials such as nickel or iron are still needed for lab-grown diamonds. This is not true for our technology: Nevermined diamonds are produced using the resource-efficient CVD process, which does not require these metals. Furthermore, our hydrogen does not come from coal-fired power generation, as is often claimed. Instead, we use electrolysis to obtain hydrogen from water, using 100% certified green electricity. The water consumption per carat is less than 1ml and is almost completely recycled. 

Nevermined therefore not only stands for ‘never mined’, but for a new standard: transparent, climate-friendly and uncompromising. For diamond production that delivers what it promises.


Our lab-grown diamonds
Yes, lab-grown diamonds are real diamonds and are in no way inferior to natural diamonds. They have the same chemical composition, crystal structure and visual properties as natural diamonds, but they are grown in the laboratory under controlled and fair conditions, making them a sustainable alternative.
Our lab-grown diamonds are grown using the CVD (chemical vapour deposition) process in special facilities. Carbon atoms are deposited from a gas phase onto a diamond substrate to form real diamonds.
The 4 Cs are criteria for determining diamond quality. These are recorded using a corresponding certificate: Carat, Colour, Clarity and Cut. At Nevermined, all diamonds are evaluated and certified according to these criteria to ensure the highest quality and authenticity.
Compared to mined diamonds, lab-grown diamonds avoid the negative effects of mining such as environmental destruction and social conflicts caused by inhumane working conditions, for instance. In addition, the diamonds grown in our laboratory enable short delivery routes, minimise the environmental footprint and offer an ethically conflict-free alternative.
We are constantly striving to make our production more sustainable, taking steps such as covering our energy requirements exclusively using renewable sources and further optimising our supply chains. Although we're on the right track, there is always room for improvement.
We certify all our nevermined diamonds from 0.5 carats. We are happy to re-measure or certify certain diamonds on request. Please use our contact form for this purpose.

Sustainability
At Nevermined, the rough diamonds are grown using the CVD process at our factory in Essen, Germany. We use certified green electricity and prioritise short delivery routes to ensure sustainable and transparent production.
We are constantly working on improvements to our production and supply chain to help us become even more sustainable. This includes the use of renewable energies, the reduction of waste and emissions and the promotion of fair working conditions along our entire value chain.
Yes, it's hugely important to us at Nevermined that we ensure our diamonds are produced ethically, conflict-free and under fair working conditions. With our local production in Germany and our transparent supply chains, we can offer 100% certainty about the origin of our diamonds.
We support social projects such as the Earth Child Project, which teaches disadvantaged children valuable skills for an environmentally conscious lifestyle. Through our partnership with this charitable organisation, we are helping to promote education and sustainability in disadvantaged communities.
