Sometimes I wish I had studied geology. All I know is that both of us like rocks, and we can't resist collecting them from time to time when we're hiking or on the beach. These four rocks, one shaped like a heart, come from the watercolours featured in the August page of the 2010 calendar. 25cm (1") each, sold as a set and packaged in a small bag.
