More commonly known SiO2 gemstones
- Common Quartz
- amorphous forms (properties similar to: chalcedon, opal, obsidian, ...)
mechanosynthesis would allow for synthesis of pseudo amorphous configurations
Especially interesting since unusually hard and dense
- Stishovite –– may be transitionable into other gemstomes with the same rutile structure forming pseudo phase diagrams
- Seifertite –– (scrutinyte structure)
Both are metastable very hard and very dense.
They may not be very resilient against high temperatures.
Other polymorphs of SiO2
