This is a 1" or 25mm Hand Carved Chinese Turquoise Shou Bead. The material is natural (not stabilized) turquoise in a gray-green tone with commonly occurring dark gray veining. Two sides of the bead have a round area inscribed with the Chinese shou symbol, the word for longevity. In Chinese traditional thought, shou is one of three blessings and important goals in life. The remainder of the bead has a curvilinear design with pinholes around the symbol and around the 2mm (0.0787") stringing holes. Maker and exact age are unknown. However, the original owner of this bead purchased it about 40 years ago. This 25mm Hand Carved Chinese Turquoise Shou Bead is in very good condition with no damage or wear.
