It is very important for curling clubs to have in place a long term game plan when it comes to their stones.
Curling stones are a curling club s biggest asset.
Therefore, knowing what type of granite your stones are made from will allow you to better assess your stones and help you to determine what your club should be considering for your stones future. There have been other types of granites that have been tried in curling stone manufacturing, such as granite from India and black Canadian granite. These granites were quickly dismissed, as they never withstood the game of curling the same as the granites in the following descriptions. If your club has blue hone, keanie, or common green ailsa craig stones, they can be used as a trade in for a set of new trefor stones or insert stones. The trade in value will depend on what type of granite that your club s stones are made from.
