Your destination for wearing precious yet sustainable change, KINRADEN is a Danish jewellery brand developed with respect for people and the environment. With its minimal design, unique materials and sustainability ethos, KINRADEN leads the way for pioneering conscious jewels. All their modern and luxurious pieces are handcrafted from purified pre-used silver and gold and embedded with signature velvet black Mpingo diamonds harvested from WWF-protected forests in Tanzania. They create lust worthy pieces you’ll fall so in love with that you’d want to learn more about their sustainability birth story.


Motivated by the harsh reality that soon the world will run out of gold, their sustainability agenda revolves around recycled materials and circularity. The brand has used recycled silver and gold since it was founded and combined these fine materials with Mpingo leftover wood from musical instrument production. That resulted in novel and enduring jewellery designs that are sourced and produced in the gentlest possible manner.


The idea came from Sarah Müllertz, who as a former architect, has worked with concepts and brands for many years. In her own words, she still works with the mind of an architect, only on a much smaller scale. Her sculptural jewellery evolves from the intersection between architecture and design, and is strongly influenced by the Danish and Japanese design traditions. Taking cues from international avant-garde art and fashion, these fun and bold pieces grow more beautiful when worn over time, as they are designed to last for generations. Sarah also finds endless inspiration in Emily Dickinson's romantic yet melancholic poetry, and always chooses the collections’ names based on Dickinson's universe.


Driven by their passion for a more sustainable lifestyle, KINRADEN wishes to build a universe based on honest interactions between humans and nature. The name KINRADEN stems from the old English word ‘kindred’, meaning ‘related through blood’. Their philosophy is thus based on the belief that everything we do inevitably affects the lives of others. As a result, the high-quality expression of their jewellery and circular production need to serve a function and help examine the world around us.


Brand Ethos

KINRADEN is a Danish brand founded by Sarah Müllertz in 2014. The brand was born from a passion for beautiful, luxurious design and conscious transformation. With sustainability and tradition in focus, their eco-gentle jewellery is handcrafted from highly purified pre-used gold and sterling silver embedded with signature Mpingo diamonds. All materials used are certified according to strict standards for sustainability, such as the black diamond-cut Mpingo heartwood, found only in FSC-certified old-growth forests in Tanzania. Adapting a circular mindset and business model, KINRADEN is interested in creating enduring beauty and making a positive impact on our planet and its inhabitants.

Brand sustainability

The brand was created with a passion for excellent design and style based on sustainable and respectful interactions. Each stage of KINRADEN's production process has a purpose and serves a specific goal. They push back against illegal businesses exploiting people, nature and the future of our planet. KINRADEN will never compromise on their beliefs and will continue to use their business humanism to inspire and implement positive change through fair, circular and sustainable solutions.


Natural & Recycled Materials

Rather than causing harm when sourcing for their materials, KINRADEN aims to help nature heal. They refuse to consume Earth’s most valuable minerals and cause further damage to our lands, so they insist on using raw materials already at hand or readily restorable. Their jewellery never involves the use of virgin metals, but only recycled gold and silver, which they purify down to 18-carat gold and 925 sterling silver through the most eco-gentle processes they can find. It is in no way easier or cheaper to do so, but the brand hopes to inspire others to follow the same path and use the riches already at hand.


Sustainable Harvesting

Traditionally mined diamonds were never an option for KINRADEN. After careful investigation, they found the most stunning conscious material that doesn’t leave a dent on nature. The dark heartwood of Mpingo, which gives it its western name of African Blackwood, is one of the world’s densest, durable, and most economically valuable growing materials available. Sustainably harvested in only one place in the world, the Mpingo tree is protected and certified by WWF in the thriving forests of Tanzania.



Durable & Certified Materials Used

All the brand's materials are certified according to strict sustainability standards and purchased with careful respect for both people and nature. KINRADEN works with precious FSC-certified leftover wood from classical wind instrument production and enlists the help of skilled diamond cutters to hand cut and polish it using traditional diamond cutting techniques. The deep black and velvety luster of the polished Mpingo Blackwood creates a lovely contrast to their metals, which by now has become the brand’s signature design.


Social Sustainability

As a modern and responsible business, KINRADEN has chosen to incorporate two of the 17 UN’s Sustainable Development Goals in the way they develop their operations. The UN Goal no. 8 refers to their efforts in empowering people through fair and decent work. Their jewellery is handcrafted by certified goldsmiths at a high standard production facility in Thailand, run entirely by women. The company ensures that everyone they work with is always treated with fairness and respect and is able to make a dignified living from their work.


Responsible Consumption & Circular Production

Beyond that, they also work with Goal no. 12, which stands for pursuing a sustainable and circular production. KINRADEN is all about lasting relevance and slowly handmade jewellery to be loved for generations to come. As a circular company, they are committed to minimize their negative impact on the world’s limited natural resources and create sustainable production loops. They use the purest materials that can seamlessly be reused or reengineered, and aim for neutral energy consumption and zero waste, like in their multi-use organic paper packaging.

The Comarché Notes

KINRADEN manages to integrate sustainability without ever compromising on aesthetics. KINRADEN allows you to explore a new side of yourself with their conscious jewellery, embellished with FSC-certified and WWF protected rare Mpingo Blackwood diamonds.

UN’s Sustainable Development Goals

Goal 8: Decent work and economic growth image Goal 8: Decent work and economic growth

Over the past 25 years the number of workers living in extreme poverty has declined dramatically, despite the lasting impact of the 2008 economic crisis and global recession. In developing countries, the middle class now makes up more than 34 percent of total employment – a number that has almost tripled between 1991 and 2015.

However, as the global economy continues to recover we are seeing slower growth, widening inequalities, and not enough jobs to keep up with a growing labour force. According to the International Labour Organization, more than 204 million people were unemployed in 2015.

The SDGs promote sustained economic growth, higher levels of productivity and technological innovation. Encouraging entrepreneurship and job creation are key to this, as are effective measures to eradicate forced labour, slavery and human trafficking. With these targets in mind, the goal is to achieve full and productive employment, and decent work, for all women and men by 2030.

Goal 12: Responsible consumption and production image Goal 12: Responsible consumption and production

Achieving economic growth and sustainable development requires that we urgently reduce our ecological footprint by changing the way we produce and consume goods and resources. Agriculture is the biggest user of water worldwide, and irrigation now claims close to 70 percent of all freshwater for human use.

The efficient management of our shared natural resources, and the way we dispose of toxic waste and pollutants, are important targets to achieve this goal. Encouraging industries, businesses and consumers to recycle and reduce waste is equally important, as is supporting developing countries to move towards more sustainable patterns of consumption by 2030.

A large share of the world population is still consuming far too little to meet even their basic needs.  Halving the per capita of global food waste at the retailer and consumer levels is also important for creating more efficient production and supply chains. This can help with food security, and shift us towards a more resource efficient economy.

Sustainable highlights on brand level

  • This indicates that the brand has actively sought out Fair Working Conditions for the producers of its product(s).

Product Lifecycle


The Design Phase is a crucial part of determining a product’s sustainable capabilities. We’ve chosen to highlight a few genius steps that enable a sustainable product right from the beginning.

    Material & Material Extraction

    The materials used for a certain product and how these materials come to life are of crucial importance to the sustainable capabilities we seek in products.

      Transportation of Materials

      This step relates to the transportation of the raw materials from when they are first obtained (harvested etc.) to the production site. Obviously, the closer to the production site, the better.


        Obviously, the production of a certain product has an impact on the overall level of sustainability. Luckily, many manufacturers have now taken steps towards more sustainable production methods.


          How a brand chooses to package its products will have a significant influence of the carbon impact from packaging and transportation.


            This step relates to the distribution of products when they have been produced. Obviously, the closer to the brand’s warehouse, the better.


              How you choose to use and take care of a product has a bigger impact than you think. Just think about how much longer a shirt lasts if it has been washed in the right way.

                End of life

                At this step, there is no way out and we have to find some way of discarding our product. How we discard a product will significantly influence the opportunity of reusing materials used.
