For her gold and silver jewellery Ulrike Ramin uses recycled gold and silver that she sources from Burger Edelmetalle in Keltern, Germany, a refinery for precious metal that puts an emphasize on materials with a proven identity. The recycling of precious metals significantly reduces the demand for exploitation of related natural resources. This prevents a company like Dr. Bernhard Burger AG from exploiting workers in gold mines. In addition, the processing of precious metals already available on the market limits the inflow of new quantities, which in turn has a positive effect on the value of existing jewellery.

For these good reasons, the Dr. Bernhard Burger AG successfully completed the certification process in June 2013 under the criteria of the Responsible Jewellery Council (RJC) and has since been officially certified member of the RJC. The mission of the RJC is the commitment to promote ethical, social and environmental practices while respecting human rights.
