| Itīs never a good idea to sacrifice nacre thickness for a rounder shape. The pearls wont last as long and luster is often a sign of thick nacre (even if you indeed can find pearls with thin nacre that have a nice luster, but they wont glow from within).
A pearl with thick nacre more often are less round than pearls with thin nacre, because the bead in the thin nacred ones only have a thin layer over it, I saw the term "pearl plated beads" somewhere on the forum and it comes to mind. But it is possibly to find round pearls no matter what nacre thickness the pearls have, so you donīt have to sacrifice anything I think. Even if the pearls probably wont be of a perfect spherical shape as akoyas often are if they are freshwaters. |
