Take a look at the Clogau earrings we currently have in stock. Crafted in 925 sterling silver and 9ct gold, every pair of earrings will contain rare Welsh gold, as worn by the British Royal Family in their wedding bands. Welsh gold, the rarest gold in the world, comes from the St David's gold mines in Snowdonia, Wales. Because of this every Clogau piece of jewellery is highly collectable.
