Skip the ice; Serve your drinks on the rocks. 

These innovative soapstone cubes were designed by Andrew Hellman, a big fan of single malt scotch, who wanted to chill his spirits without diluting them. After much research, he came up with the idea of using natural soapstone to chill drinks due to its softness (won't scratch the glass) and its unique ability to retain temperature for extended periods of time. Milled in Perkinsville, Vermont by the oldest soapstone workshop in the United States. 

Simply chill the stones. Add three to your next drink, let stand for five minutes and enjoy. Sold as a set of nine with muslin storage bag.
