Perfect for those that like to nurse a slow drink in the summer sun, these unusual cubes ensure your drink isn't watered down by melting ice. Mined in Sweden, these cubes are made from natural pollution-free stone. You just pop them in the freezer for an hour before use, and when finished give them a quick rinse before returning them to their leather pouch. A great gift for someone who has everything, the rough stone finish brings a captivating richness to quiet drinks and charms guests at cocktail parties. Bringing new meaning to “On the rocks”, a set of ten Nordic Rock Ice Cubes are £15.99 from Mocha.uk.com.
