| Natural pearls regularly show no (or just a very tiny) intruder, shell, or whatever. I started this threat on the natural pearl forum with these pearls in mind.
For what reason the mollusk started a spontanious pearl formation?
For no reason at all? as an impuls on any stimulation? because the mollusk was irritated? or was the lovely nacre ball the result of some exercise?
