Natural springs bring us some of earth's best water. Liquid, filtered through miles of rock, finds its way to the surface - now purified, and as hot or cold as the stone that carried it there.

We've taken some of this rock from deep beneath the earth's surface, to bring you the most refined drinking experience of all time. Introducing The Stone Cup, artisan-milled from metamorphic rock. Cool it or heat it, to keep your drink at its perfect temperature - and always at its purest taste.
