Horlyne obtains RJC CoC certification

Horlyne strengthens its commitment to responsible and sustainable jewellery and watchmaking. Already certified to the RJC Code of Practices (CoP) since July 2018, our company has now reached another significant milestone: as of 19 November 2025, Horlyne is also certified to the RJC Chain of Custody (CoC) standard.

These two certifications, awarded by the Responsible Jewellery Council, are major international benchmarks for stakeholders in the high-end jewellery and watchmaking sectors. They recognise companies that uphold strict standards in ethics, sustainability, and transparency.

Concrete and measurable commitments

The combined achievement of the CoP and CoC certifications demonstrates the strength of our approach:

• Compliance with the highest ethical, social, and environmental standards
  The CoP certification confirms that our practices meet international standards in working conditions, professional integrity, and responsible resource management.
• Full and reliable material traceability
  Thanks to the CoC certification, our products now benefit from a fully certified supply chain, offering our partners complete transparency regarding the origin and processing of precious materials.
• Strengthening our commitment to sustainable jewellery
  These certifications underline our determination to contribute to a more responsible industry, where quality, integrity, and sustainability go hand in hand.

A long-term commitment

For Horlyne, this new certification is not an end in itself, but an additional step in a long-standing commitment. It reflects the rigour of our teams and our ambition to continually progress in order to offer our clients and partners a level of excellence that meets their expectations.

Building the future with confidence

By reinforcing our engagement within the Responsible Jewellery Council, we reaffirm our intention to build lasting relationships founded on transparency, responsibility, and excellence.
