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
Aquamarine (film) next three days. They use strategies found in the magazines that Claire and Hayley read, and proceed to stalk Raymond around town so he can notice Aquamarine more and more. At the street fair, Raymond spends the day with Aquamarine. While spending time together alone in the water watching the sunset, he mentions that he wants to see her at a party, The Last Splash, the following night, but she flees before she can give him an answer knowing a sunset can cause her legs to transform back into a tail. Claire and Hailey show Aquamarine a water tower for
