For the 2026 Winter Olympics, Kays Scotland delivered 132 curling stones, all certified by the International Olympic Committee. A single curling stone costs over $960. That makes a full set of 16 stones worth more than $15,000. Since 2006, every stone used in the Winter Games has come from just one company, which has been making curling stones since 1851. But producing these stones isn’t easy. For every stone it makes, Kays uses granite from one tiny island off the coast of Scotland called Ailsa Craig. By combining Ailsa Craig’s common green and blue hone granites, Kays produces the only stones allowed in World Curling Federation contests and the Winter Olympics. 00:00 - Intro 01:00 - Kays Scotland 01:43 - Sourcing the granite 02:59 - Unique granite 03:45 - Cutting and shaping the granite 06:10 - Polishing the curling stone 06:34 - The final curling stone 07:19 - History of curling 08:12 - The Winter Olympics and beyond 10:03 - Credits Also read "26 photos show how some Olympic ven...
