Rationale |
No free use or Public Domain image known to show a hibonite crystal imaged in natural light that has a bluish cast though it may be black as hibonite appears in meteorites but this crystal is from Madagaskar. |

Fair use for blue astronomy edit
To illustrate the subject in question (blue hibonite as has also been found in meteorites), since no picture can be obtained of the actual hibonite in natural color as occurring in meteorites.
The image linked here is claimed to be used under fair use as:
- it is a scientifically significant image of the blue hibonite from an Earth source;
- it is of much lower resolution than the original (copies made from it will be of very inferior quality),
- the photo is only being used for informational/educational purposes.
- Its inclusion in the article adds significantly to the article because it shows that blue hibonite not only exists on Earth but may have a different composition than the often occurring natural brown or black hibonite to the general public.
