Our Suppliers

We source our recycled sterling silver and other metals from The Bangkok Assay Office. With almost 40 years of service in the jewelry and precious metal industry, they consistently supply metals that meet Fionna’s incredibly high standards. The Bangkok Assay Office is certified by the Responsible Jewellery Council, meaning their supply chain meets the highest health and safety, human rights, fair labour, governance, and environmental practice standards, from end-to-end.

The gold used to create Fionna’s industry-leading 14K gold vermeil is sourced from Nardi Gold. An institution in the Arezzo goldsmith district – Italy’s “Capital of Jewelry” – Nardi Gold has supplied superior gold to some of the world’s best-loved jewelry brands for decades. Nardi Gold is built on the same family-first, expert-led ethos as Fionna, making them the perfect parter in our mission to create the finest jewelry without compromising on quality or price. 

Our hand-selected and rigorously tested natural gemstones come from Bright Future Gems Co. They are trusted across Asia and the world as one of the biggest and best suppliers of precious and semi-precious stones. Despite its size, Bright Future places a high value on corporate responsibility and trust, ensuring employees and customers alike are treated with respect.

Every piece of Fionna jewelry is carefully considered, down to the last detail. W.R. Cobb Company supplies the findings – that’s the clasps and posts, among other things – in every piece of Fionna jewelry. The superior quality of these essential components means every piece of Fionna jewelry can be enjoyed for years to come. W.R. Cobb Company has also fostered a strong commitment to corporate responsibility, adhering to the RJC’s Code of Practices standards across the entirety of their 150-year-old operation.
