Ethically Sourced. Consciously Made.

At Tang&Co., we are deeply committed to responsible sourcing. Every diamond we offer is conflict-free and fully compliant with the Kimberley Process and relevant international standards.

Our Diamond Policy

We exclusively source diamonds from trusted suppliers who uphold the highest ethical practices.
Every diamond is certified conflict-free, and we maintain rigorous documentation throughout the supply chain.
To date, no Tang&Co. jewelry has included conflict diamonds. In the rare event of a violation, we will immediately terminate any partnership and take appropriate legal action.

Our Gold Policy

We work with partners who share our values — including certified ethical mines and reputable gold recyclers.
Wherever possible, we use recycled gold to reduce environmental impact while maintaining the integrity and beauty of each piece.
We refuse to engage with any organization that falls short on social, environmental, or human rights standards.

Supplier Screening

Every Tang&Co supplier undergoes a thorough screening process.
We assess transaction history, sourcing transparency, and business practices to ensure they meet our uncompromising ethical requirements.
