Responsible actions in line with the guidelines of the OECD

We adhere to the most stringent standards of ethical action. Gold that we process into our C.HAFNER & C-HAFNER & HILDERBRAND SA alloys comes from our own recycling process! What this means is that the input material of our recycling process consists exclusively of secondary material, that is waste from the industrial processing and finishing of precious metals, such as for jewellery and watch production, as well as old gold which for example was previously processed into jewellery, coins or dental gold.

Precious metals from C.HAFNER therefore contain no material:

  • that was acquired through human rights violations such as child labour or slavery
  • whereby extraction and processing destroys the earth’s surface
  • which serves to support criminal or terrorist activities such as money laundering, tax evasion
  • which is harmful to the environment

Supply Chain Responsibility


Responsible ethical behaviour has always been a driving force for C.HAFNER. To give expression to this sentiment, C-HAFNER has been a member of Urban Mining e.V. since 2015. This association considers cities and settlements as raw material mines, in which valuable resources of various kinds are bound for different lengths of time, but subsequently become free and usable again. This also includes precious metals. When it comes to gold mining, C.HAFNER relies exclusively on precious metal recycling, i.e. urban mining. After all, recycled precious metal from local sources is a useful resource, but it is most importantly a necessity for companies that act responsibly! C.HAFNER thus makes an important contribution to the preservation of the environment and demonstrates respect for human rights..


The Responsible Jewellery Council (RJC) is an international association of companies in the jewellery and watchmaking industry, as well as their suppliers, with the aim of promoting an ethical, social and environmentally safe and human corporate policy. Companies bind themselves to these basic principles by issuing a declaration of commitment on corporate practice, known as the Code of Practices (CoP).

Both C. HAFNER & HILDERBRAND SA are certified Member of the RJC with both CoC and COP certifications.
