You've heard of whiskey stones, but few carry the ancient history that these possess. The stones are dark granulite Hornblende: a 940-million-year-old stone from the Trois-Rivieres area in Canada. Each stone is deep black and finely crystalline with a dark green translucence and bursts of coppery colors. They're perfect for keeping whiskey cold without watering down your dram and arrive as a set of four stones in a walnut case that is made in Quebec and coated with oil to protect the wood.
