Spinach-green nephrite from the Lake Baikal region of Russia is known as "Russian jade". Jadeite is the rarer of the two varieties of jade, and as a result it is more precious.
Jade is the stone of calm in the midst of storm. Its action balances nerves and soothes cardiac rhythm. A piece of Jade kept in a pocket or on a pendant to stroke from time to time recharges energy, and traditionally guards against illness. Jade may also be used to temper the shock or fear of the very young or very old being cared for in the hospital or away from home and family.
