Curling stones used in the Winter Olympics are made exclusively in the UK, with granite sourced from only two locations: the Scottish island of Ailsa Craig and the Trefor Granite Quarry in Wales. The stones, weighing between 17.24kg and 19.96kg, are manufactured by Kays of Scotland, a company that has been producing them since 1851 and holds exclusive rights to the Ailsa Craig granite.
During the Sochi Winter Olympics, Team GB won silver and bronze medals in curling, bringing global attention to the sport. The stones used in the games were supplied by Kays, highlighting the continued importance of traditional British manufacturing in niche markets.
Kays of Scotland is one of only two manufacturers of curling stones in the world, the other also being based in the UK. The company's long history and exclusive access to the unique granite from Ailsa Craig ensure that British-made stones remain essential to the sport at all levels, from local clubs to international competitions.
