regarding RJC COP
As a certified member of the Responsible Jewellery Council (RJC), we are committed to adhering to the standards set out in the Code of Practice (COP). The RJC Code of Practice (COP) represents ethically responsible, environmentally friendly, and sustainable business practices in the supply chain of gold, platinum group metals, silver, diamonds, and colored gemstones. RJC members—from mining companies and refineries to diamond dealers, precious metal refineries, jewelry manufacturers, and retailers—commit to preventing corruption, money laundering, and the financing of conflict and terrorism. They ensure healthy and safe working conditions. They are committed to upholding human rights and the sustainable management of natural resources. Among the RJC standards for companies in the supply chain is the public reporting of due diligence activities based on the OECD Due Diligence Guidance (“Guidelines for Due Diligence to Promote Responsible Supply Chains for Minerals from Conflict-Affected and High-Risk Areas”).s
Our supply chain policy regarding the processed precious metals, diamonds and gemstones is published on our website at https://www.kriegernet.com/supplychainpolicy.
The due diligence process has been implemented, and responsibilities have been defined. A corresponding company document has been created. The goal is to exercise the necessary care in the selection and monitoring of supply chains.
This system is reviewed annually and adjusted as needed. The core elements are: identification of the supplier and the origin of the material through access to international data.
Risk assessments along the supply chain are conducted in accordance with the OECD Due Diligence Guidance. Our suppliers in the precious metal, diamond, and colored gemstone supply chain have signed our Code of Conduct, completed the KYC form, and identified their beneficial owners. Our supply chain policy is published on our website. A risk analysis has been conducted, and measures have been established to regulate the review and monitoring of our suppliers. Responsibilities have been defined. Should any violations of OECD due diligence be identified, appropriate investigations will be initiated, and measures will be taken that may result in the suspension or even termination of the business relationship. Furthermore, we value long-term business relationships and work with a manageable and consistent pool of suppliers. We generally do not source from CAHRAs (Conflict and High-Risk Areas). When purchasing precious metals, we focus on suppliers certified by the RJC. There have been no complaints or concerns regarding the RJC COP (Code of Practice) actions via the publicly available compliance email or other communication channels. No red flags were identified during the reporting period; therefore, there is currently no need for action regarding risk mitigation.
All measures and processes are subject to continuous review and, if necessary, adjustment with the aim of improvement.
