How much do curling stones cost? Brand new curling stones cost between $500 and $900 each.

Stones: Also known as rocks, curling stones are made of a rare, dense granite that is quarried on Scotland's Ailsa Craig. The stones must weigh between 38 and 44 pounds. On average, stones weight about 42 pounds (19.1 kg). In Olympic competition, one set of stones has red handles and the other has yellow handles.

Since 2006, every stone used in the Olympic Winter Games has come from Kays of Scotland. The company has produced curling stones since 1851. But making 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.

The finished curling stones cost between £400 and £450 each and you need 16 of them for a sheet, or set. And it is not just the stones that have to be perfect, so does the ice.
