Dear Student
Cyclosilicates (Ring Silicates)

If two of the oxygens are shared and the structure is arranged in a ring, such as that shown here, we get the basic structural unit of the cyclosilcates or ring silicates.  Shown here is a six membered ring forming the structural group Si6O18-12.  Three membered rings, Si3O9-6, four membered rings, Si4O12-8, and five membered rings Si5O15-10are also possible.  A good example of a cyclosilicate is the mineral Beryl Be3Al2Si6O18.

We hope that clarifies your query.
