Gemstones & Certification
Exceptional gemstones. Carefully sourced.

Our approach is guided by a commitment to quality, authenticity and transparency. We source gemstones through established and reputable suppliers, selecting each for its individual beauty, character and quality.
Every gemstone we offer is accompanied by a report or certificate from an independent gemmological laboratory, alongside a separate Green River Gems certificate of purchase recording the stone’s documented details.
Laboratory reports vary in scope. Depending on the report, they may identify the gemstone, describe detectable treatments and provide an opinion on origin. Our own purchase certificate is not an independent laboratory assessment.
Our expertise has developed through research, education and hands-on experience, complemented by an ongoing commitment to further professional development in gemmology.
Naturally Presented
Every gemstone is securely protected in an appropriate gemstone case and thoughtfully wrapped in soft ivory linen with a simple forest-green ribbon. Independent laboratory documentation and our certificate of purchase accompany the stone. An optional keepsake presentation box may be introduced in future.
Formed by nature. Treasured for generations.
