Keshi freshwater pearls are another type of freshwater pearls, characterized by their incredible luster.
In appearance and shape, they can resemble baroque freshwater pearls a bit, but where a keshi freshwater pearl stands out is through the extraordinary luster that each individual pearl possesses.
Another point where keshi freshwater pearls differ from the others is that they are often produced by chance. Pearls are often cultivated, meaning that humans have had a hand in the production of the freshwater pearls. In the case of keshi freshwater pearls, humans have not inserted mollusk tissue into the mussel. Here, the freshwater pearls form by an "accident", meaning that nothing has been inserted into the mussel to kickstart the pearl production process.
