Quartzite Jasper Pebble

Though jasper naturally exhibits a dull luster, the silica-based mineral may be polished to a high sheen. It is, therefore, commonly utilized as a gemstone and for ornamental items, such as vases. Widely distributed and often occurring as detrital pebbles, in earlier times, many people kept jasper at hand for medicinal and spiritual purposes. According to various myths, jasper pebbles could toughen one’s stomach, drive off evil spirits, provide protection from spider bites, and instigate rainstorms. Even today mystical properties are sometimes associated with jasper, but the chalcedony is more generally appreciated and sought after for its beauty.
