Next question:

Some facts about this mineral:
[list][*]This mineral belongs to the class that constitutes around 90% of the Earth's crust.
[*]The dimorph of this mineral can sometimes be associated with pyrophanite.
[*]Parts of the mineral may appear brown due to surface oxidation.[/list]
1) ID the mineral.
2) This mineral actually contains six elements: Mn, Fe, Mg, O, Si, and one other. What is the sixth element that is represented by the blue spheres in the image above?
3) What mineral class does this specimen belong to?
4) This specimen is the official state gem of what state?
5) Give another mineral on the 2012 SO Rock/Mineral list that also belongs to the same mineral class.
