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) man she doesn't know when she returns home. She also explains that if you help a mermaid, you get a wish. Aquamarine immediately sets her eyes on Raymond (Jake McDorman), the lifeguard who Hailey and Claire have had a crush on for years. They are reluctant at first, but know it is their last hope, so they agree to help her. However, because Aquamarine isn't human, she doesn't understand that people don't just love one another instantly, and is rejected by Raymond when they first meet. Still, the girls promise to make Raymond fall in love with Aquamarine over the
