Overview
This is a classic circular pewter brooch featuring a deeply cast Celtic quaternary knot design with a darkened, textured background. Crafted by the renowned Cornish workshop St Justin, it represents a modern revival of ancient Insular art traditions.
Story
In 1984, a small group of artisans in Cornwall began recreating the magic of ancient Celtic metalwork. This brooch carries a quaternary knot, an endless loop representing eternity, protection, and the four seasons.
Maker / Origin
St Justin was founded in Cornwall, England, in 1984, starting in a small shed before growing into a highly respected name in pewter and bronze jewelry. They specialize in historical revivals, particularly Celtic, Pictish, and Viking designs, handcrafting each piece in the UK to keep traditional metalworking alive.
Condition & Value
The brooch is in very good vintage condition. The pewter shows light surface wear and a gentle patina consistent with age, while the pin and safety clasp on the reverse remain fully functional. Excellent preservation of the dark background contrast. Pewter jewelry by St Justin is highly collectible but widely produced.
