Mineral site, and from there further subdivided by the chemistry of the W site. The Y and Z sites can accommodate a variety of cations, especially various transition metals; this variability in structural transition metal content gives the tourmaline group greater variability in colour. Other cyclosilicates include beryl, AlBeSiO, whose varieties include the gemstones emerald (green) and aquamarine (bluish). Cordierite is structurally similar to beryl, and is a common metamorphic mineral. Sorosilicates, also termed disilicates, have tetrahedron-tetrahedron bonding at one oxygen, which results in a 2:7 ratio of silicon to oxygen. The resultant common structural element is the [SiO] group. The
The Knights of Emerald the Emerald Kingdom, seeing as the Emerald Knights are trained and will live there for the majority of their lives. The Emerald Knights are an elite group of warriors and magicians that are trained in the Emerald Kingdom. Children who show off magical capabilities are brought to the castle to be evaluated by a magician, and then deemed either capable or incapable of becoming a knight. From infancy to their teens, children will study under the magician and previous knights as well as warriors. They then will be employed as Squires to the Emerald Knights, helping them and providing for
