What does a buyer check before sourcing jewellery?
They check metal purity and hallmarking for the destination market, stone certification and disclosure of any treatment, and responsible sourcing documentation. Treatment disclosure is a legal requirement in most markets and the most common source of disputes.
A retail buyer is sourcing a range where an undisclosed treatment would become a consumer protection problem.

Questions suppliers ask
Why is treatment disclosure worth leading with?
Because non-disclosure is both illegal in most markets and the fastest way to lose a retail relationship permanently. A supplier who discloses treatments as standard practice, in writing, is immediately more trustworthy than the many who disclose only when asked.
How should responsible sourcing be presented?
With the documentation you actually hold and the scheme it belongs to, rather than a general statement about ethics. Retail buyers face public scrutiny and need documentation they can point to, not assurance they would have to defend themselves.
What does a retail buyer need beyond product?
Repeatability and security. They need to know a design can be reordered to the same standard and that high-value goods move safely and insured. Both are unglamorous and both decide whether a range is commercially workable.
