Ailsa Craig granite shapes Olympic curling stones
Dilaporkan oleh AI Gambar dihasilkan oleh AI
Every curling stone used in the 2026 Winter Olympics comes from granite quarried on Ailsa Craig, a small uninhabited island off Scotland's coast. This unique material ensures durability and precise movement on the ice, as highlighted by Team USA's recent silver medal in mixed doubles curling. The stones' exceptional properties have made them the standard since the sport's Olympic debut in 1924.
