Most of the online resources i've read that explain pearl quality and grading seem to assert that in cultured saltwater pearls, a thicker deposit of nacre. Homogeneous nacre allow this special colour effect, as if colours of reliefs and hollow parts doing cumulative actions, and so much as carving is deep, up to a limit, when light can't touch the bottom of carving There are no standards for nacre thickness in south sea pearl production, at least not in the way there is in french polynesia

The composition of nacre is unique within certain branches, and certain forms of nacre facilitate pearl production. I don't think you could tell with tahitians because of the nacre not being transparent Twj, there is a relationship between luster and nacre thickness in that pearls with great luster usually have thicker nacre, but thick nacre is no guarantee of luster There is also the matter of how the crystals of aragonite are laid down.
