Scallops do occasionally produce pearls, though scallop pearls do not have the buildup of translucent layers or "nacre" which give desirability to the pearls of the feather oysters, and usually lack both lustre and iridescence.
 They can be dull, small, and of varying colour, but exceptions occur that are appreciated for their aesthetic qualities.
