I think the difference between nucleated pearls and seedless pearls is as follows:

1, the cultivation methods are different: nucleated pearls are transplanted from the cell membrane of artificial mussels, and they are all nacre from the inside out, with a growth period of 4-5 years; Seedless pearls grow around the spherical mother-of-pearl nucleus for 2-3 years.

2. Different colors: The color, luster, halo, surface features and patterns of nucleated pearls are basically the same as those of natural pearls; There are often great differences in color between seedless pearls and natural pearls.

3. Different shapes: nucleated pearls are generally more spherical than natural pearls; Seedless pearls are generally oblate or teardrop-shaped, with poor roundness.

4, different uses: nucleated pearls are generally used for jewelry making; Seedless pearls are generally used for ornaments or jewelry inlay.

5. The formation mechanism is different: nucleated pearls are formed by artificial implantation of nucellus and cell fragments into the mantle of mother shell; Seedless pearls are artificial or natural cells or foreign bodies implanted or invaded into the shell of the mother shell to form pearls.
