Responsible sourcing requires more than intent. It requires systems, oversight, and documentation that hold across regulatory change and operational scale.
Our offices in Antwerp and Mumbai and our manufacturing unit in Surat all operate under Responsible Jewellery Council (RJC) certification, aligning our operations with internationally recognised standards across every transaction we undertake.
The Responsible Jewellery Council sets the benchmark for ethical, social and environmental practice in the jewellery supply chain. Copies of our certificates are available on request.
Our Antwerp headquarters operates under full RJC certification, covering trading practices, sourcing conduct, and documentation integrity.

Active GovernanceCountry of origin is documented at source level, enabling full geographic traceability from mine to supply.

The specific polishing facility is documented, supporting end-to-end accountability within the supply chain.
Touch Stone supplies natural diamonds exclusively. Laboratory-grown diamonds cannot be told apart from natural diamonds by eye — only by instrument. That is why screening is built into our process, not added at the end.
Every parcel is screened in-house using Yehuda detection equipment and De Beers’ AMS2 instrument. Parcels are also sent to HRD Antwerp or IIDGR for independent laboratory testing — as periodic checks on our own process, and on request from clients.
All rough we purchase and manufacture is covered by Kimberley Process certification, and every invoice carries a conflict-free, Kimberley Process–compliant declaration.
