Where did the curling stone come from?

Answer 1

When curling was invented in Scotland nearly 500 years ago, they would slide "river stones" (large stones worn smooth by water erosion) down lanes of ice. Over time, as the game evolved, the stones turned into the precise granite products with the plastic handles we see today.

Today, curling stones come from one of two manufacturers. Kays of Scotland creates curling stones using granite mined from Ailsa Craig, a small island off the west coast of Scotland. Meanwhile, the Canadian Curling Stone Co. creates stones using granite mined from Trefor quarry in Wales.
