where are the stones for curling made

Most modern curling stones are made from very specific types of granite quarried in just a couple of places, mainly in the UK.

Quick Scoop: Where curling stones come from

• The classic source is Ailsa Craig, a tiny uninhabited island off the west coast of Scotland in the Firth of Clyde.

• The granite there (especially “Blue Hone” and “Ailsa Craig Common Green”) is unusually dense, tough, and very low in water absorption, which stops it from chipping or eroding on ice.

• A small factory in Mauchline, East Ayrshire, Scotland (Kays Scotland) has been hand‑crafting top‑level and Olympic curling stones from this granite for over 170 years.

• Another important source for non‑Olympic stones is the Trefor quarry in Wales, which also produces a suitable, very hard granite used for curling rocks.

Put simply: the stones for high‑end and Olympic curling are made in Scotland from Ailsa Craig granite, with additional stones also made from special granite from Trefor quarry in Wales.
