(Science: marine biology, zoology) A shelly concretion, usually rounded, and having a brilliant luster, with varying tints, found in the mantle, or between the mantle and shell, of certain bivalve mollusks, especially in the pearl oysters and river mussels, and sometimes in certain univalves. It is usually due to a secretion of shelly substance around some irritating foreign particle. Its substance is the same as nacre, or mother-of-pearl. Pearls which are round, or nearly round, and of fine luster, are highly esteemed as jewels, and compare in value with the precious stones.

What sea creature is this?

I'm a diver and see them fairly often. You sometimes see them with oysters also. I've done a little pearl diving in a effort to find some beautiful pearls like those. Haven't had much luck as of yet. Nice find on the chiton.
