Stishovite a polymorph of SiO2 other than quartz that is:
- much harder
- much denser
- has higher crsytal structure symmetry (the same as rutile)
- is metastable (hopefully)
There are several other known polymorphs of silicon dioxide.
One of them is Seifertite which is also a denser and harder thah quartz.
