For the past 12 years, Rosenkrantz has worked with artisanal miners to establish small scale mines in remote parts of Africa. The first mine was located deep in the jungles of Southern Tanzania. The mine is run without the use of chemicals or machinery and Rosenkrantz works to preserve the beautiful nature surrounding the mine while supporting the local community.

The company’s CEO, Iver Rosenkrantz co-founded the World’s first all-women mine in 2019. The mine – Zimbaqua – is located in the Northern part of Zimbabwe. Read more on (

In rural African communities, the mining and trading of coloured gemstones are cultural traditions and sources of livelihoods that have been passed down for generations.

Approximately 40-50% of the coloured gemstones in Rosenkrantz jewels are sourced from small-scale and artisanal mines in East Africa. Rosenkrantz collaborates directly with the miners in order to monitor and guarantee fair treatment of people.

By sourcing directly from small-scale and artisanal miners, Rosenkrantz ensures that miners reap the rewards and compensations for their hard work. By this, the miners are also able to tell the stories behind the gemstones featured in Rosenkrantz jewellery.

Our goal is to promote responsibility and traceability in the mining and sourcing of gemstones across Africa.

“To us, being socially and environmentally responsible requires involvement. As an African brand, we endeavour to know the origin of every gemstone used to tell their stories.” Iver Rosenkrantz


Rosenkrantz considers all the facets of the materials used in jewellery: The sourcing of gemstones and precious metals – the cutting and refining – and finally, the goldsmith crafts they are worked upon.

Rosenkrantz adheres to guidelines for species sustainability (such as leathers) by The International Union for Conservation of Nature (IUCN) Red List and The Convention on International Trade in Endangered Species (CITES) Appendices.


Rosenkrantz does not use materials such as ivory, as the company supports the efforts to preserve endangered species, especially elephants and rhinos. Rosenkrantz directly supports conservation efforts in Kenya, Tanzania and Zimbabwe.

“The best way to eliminate poaching is by giving poachers in Africa an alternative source of income to support their families with. We believe artisanal and small-scale mining is a good alternative, but only if fair trade and treatment of the miners is safeguarded, in order to make the mining practice attractive.”


Through the company’s work with artisanal and small-scale miners such as Zimbaqua ( in Zimbabwe, Rosenkrantz remains committed to promoting the health and safety of the people that contribute to the company’s success.

Rosenkrantz follows the standards of the internationally recognized ISO 14001 to contribute to a better version of Africa, where people may live in harmony. At the same time, the company’s goals are aligned with the UN’s Sustainable Development Goals. Read more here:
