Meaning and Definition
A dense, high-pressure polymorph of silicon dioxide (SiO₂), formed under extreme conditions such as meteorite impacts.
A mineralogical term for a specific crystal structure of quartz, which is metastable at Earth's surface conditions and serves as an indicator of past high-pressure shock events.

FAQ
Frequently Asked Questions
No, it is extremely rare on Earth's surface and is only found in specific, heavily shocked rocks like those at meteorite impact craters.
No, it is not used in jewellery. It is a scientific specimen, typically microscopic, unstable at surface conditions, and of interest only for research.
It was named in honour of Sergei M. Stishov, a Russian physicist who first synthesized this high-pressure phase of silica.
Both are SiO₂, but stishovite has a much denser, rutile-like crystal structure formed under immense pressure, whereas quartz has a lower-density, hexagonal structure stable at surface conditions.
A dense, high-pressure polymorph of silicon dioxide (SiO₂), formed under extreme conditions such as meteorite impacts.
Stishovite is usually highly technical/scientific in register.
