Consisting of fine sand and silt consolidated by a limestone cement (calcium carbonate), these stones and their curious forms are phenomena common to certain regions of northern Quebec, particularly on the bottom of lakes of glacial origin. The North American native people have called them fairy stones, and often wore them for good luck on hunting and fishing expeditions. Lovers also offered the most beautiful ones to their beloved. Larger specimens often occupied a place of honor in dwelllings, and legend has it that thses stones protected against eveil spirits and brought about health and prosperity to the home. Many people today liken their forms to abstract art. They have a soft feel and are addictive to hold.
