Beyond Beauty: Certification and Traceability

Why clear documentation and responsible sourcing matter more than ever.

Gemstones have always inspired fascination, but buyers increasingly want to understand more than a stone’s appearance. Questions about identification, treatments, origin and sourcing are central to an informed purchase.

What an independent laboratory report tells you

Depending on the stone and the service ordered, a gemmological report may identify the material, describe detectable treatments and offer an origin opinion. The scope varies by laboratory and report type. A laboratory report is not necessarily a valuation, nor does it automatically certify ethical sourcing.

In January 2026, the Gemological Institute of America introduced redesigned coloured-stone reports and expanded selected origin-determination services. This reflects the growing importance of accessible, meaningful gemstone documentation.

The challenge of tracing a gemstone

Coloured gemstones can pass through miners, traders, cutters and dealers across several countries. That makes full chain-of-custody documentation challenging. In August 2026, SCS announced the retirement of its SCS-007 sustainably produced gemstones certification programme, citing insufficient market adoption and the complexity of tracing fragmented supply chains.

A considered approach

At Green River Gems, we favour careful sourcing through established suppliers, independent gemmological documentation and clear communication about what is — and is not — known about an individual stone. We believe confidence begins with transparency, rather than claims that go beyond the available evidence.
