Ailsa Craig

Ailsa Craig (/ˈeɪlsə/; Scots: Ailsae Craig; Scottish Gaelic: Creag Ealasaid) is an island of 99 hectares (240 acres) in the outer Firth of Clyde, 16 kilometres (10 miles) west of mainland Scotland, upon which "blue hone" microgranite has long been quarried to make curling stones. The now-uninhabited island is formed from a magmatic pluton formed during the same period of igneous activity as magmatic rocks on the nearby Isle of Arran.
