Jade is thought to be able to help a person just by being in contact with it. The feel of cool jade is said to elevate and purify thoughts, to quiet the mind, and to induce a state of contemplation. It is also believed that frequent handling of jade will cause the stone to grow even more beautiful in sheen. According to one Chinese proverb, Jade is cool because it comes from the essence of clear mountain streams. Science says that jade is cool to the touch because it is a non-conductor.
