Jade is a mineral that is highly prized for its beauty and has been treasured for centuries in many cultures around the world. It is actually composed of two distinct minerals: jadeite and nephrite. Both jadeite and nephrite are classified as silicate minerals, which means they are primarily composed of silicon and oxygen.
