This can be based on aesthetics, personality, or other attributes that seem to (subjectively) correlate to a given character.
If a character is already minerally themed, you can try to be alternative in your decision if preferred.
Rules:
1. No NSFW?
2. Any species/type of mineral is viable(?)
3. You may include reference images (if preferred).
4. Post in-character if possible.
5. If possible, put thought into your response?
I think muriel would like Coquina, as its composed of shells, pebbles, sand, ect! Lots of beachy goodness!
Censored for poooossible tryphobia?
Possibly Zincite? [This stone was apparently used historically as a crystal detector? -- It corrected radio signals, alike to how Mog listens to others' concerns?]
