Certifications and our corporate policy

At Sikno, we know the importance of certifications and corporate policy, their application guarantees quality and commitment to our values.

RJC certificate

SIKNO becomes a certified member of Responsible 
 Council (RJC),

a non-profit organisation dedicated to establishing and certifying standards throughout the supply chain for diamonds, gemstones, gold, silver and platinum group metals used in the jewellery industry.

This certification allows our suppliers and customers to be assured that our processes are based on strict quality and sustainability policies.
