Hallmarking is a centuries-old practice used to certify the authenticity and purity of precious metals. The Hallmarking Notice provides an overview of UK hallmarking and explains the approved marks customers may see on precious metal jewellery.

At Studio Playfair, each piece is hallmarked at the Edinburgh Assay Office. The Assay Office’s history traces back to 1457, when early regulation was introduced in Scotland to guarantee the purity of precious metals.

Studio Playfair jewellery carries the Edinburgh Castle hallmark, a mark used since 1485 on pieces that have passed assay. These hallmarks carry tradition, quality and trust.
