Jade is a silicate mineral best known for its green varieties, the most common of which are jadeite and nephrite. Jadeite is a variety of jade primarily composed of silicon, calcium and magnesium, while nephrite contains silicon, sodium and aluminum. For thousands of years, jade has been used for ornamental purposes and as tools due to its relative strength and durability.
