Cultured pearls kernel rounded, and therefore better roundness after beads. Natural pearls grow due to the long time, so after a fine texture beads, bead layer thick, smooth skin, there is little "blisters", and more transparent. Cultured pearl beads when tone due to short, therefore beads thin, rough texture, "wax" band-like luster and surface irregularities tend to have some "small bubble", transparency is also poor.
