When an oyster creates a pearl, the nacre does not always develop smoothly. The surface of a pearl is judged by how many marks are visible in the nacre. These imperfections can be small and unnoticeable or quite large and distinct. Like diamonds, pearls are rarely flawless. However, high luster or the way pearls are strung and set can help conceal surface markings.
