Jade is the gemstone representing the 12th wedding anniversary. Nephrite Jade is derived from the Latin word lapis nephriticus, meaning "stone of the kidney". Jade was considered a prized gem in both Chinese and Central American cultures.
In the 16th century, the Chinese believed that ingesting jade powder would prolong life and strengthen the lungs, heart, and vocal chords. It has also been told that handling jade can help one relax by absorbing some of its secret virtue into the body.
