Open Source Minerals only trades in diamonds, gems and precious metals that come from legitimate sources that can disclose origin and cutting centre practices.

We pay visits to the manufacturers and polishers and are in contact with organizations that conduct independent 3rd party verification of the mining practices.

Open Source Minerals is liable to issue the Jeweltree Foundation Quality Label. A label that guarantees supply chain transparency, social responsibility and ecological sustainability.

Part of our profit goes to this foundation to support fair trade initiatives in the diamond and jewelry trade.

We don't only believe in ethics, integrity and quality. We practice it!
