It's a silicate mineral with an unusual composition:
- Beryl contains the element beryllium.
- It is a ring silicate - the silicate tetrahedra are linked to form rings!
- Beryl commonly grows as elongate crystals with hexagonal cross sections.
- Formula Be3Al2Si6O18
Mineralogists focus on the silicate part of the formula, and represent the compound as containing isolated cyclic silicate ions Si6O186- with Be2+ and Al3+. However beryllium forms mainly covalent compounds BeO is a giant molecule with 4 coordinate beryllium atoms. As aluminium can be substituted to a small extent without disturbing the crystal by the chromium ion, Cr3+ , (which as it is as a transition metal adds color) to form the gemstone emerald. A better description of the structure is to include the beryllium in the ion which gives an infinite lattice (Be3Si6O18)n6n-
