What To Look For On The Pearl’s Surface
When pearl grading, the appearance of the surface of a pearl is one of the most important characteristics in determining its overall desirability and value. Ideally, the pearl's surface should be smooth, clean and shiny. It should have few, if any, bumps, abrasions, cracks, or other surface flaws.
Luster On The Pearl Surface Is Critical To Value
The pearl's surface luster is critical. Luster measures the brilliance and reflectivity of a pearl. The more brilliant and mirror-like the surface of the pearl is, the higher its quality. A dull or chalky surface indicates an inferior pearl.
Minor Flaws On The Pearl’s Surface Aren’t As Bad
Less-serious problems that are often found are minor scratches or abrasions, which may affect small areas of the pearl's luster or color; small spots or variations in the pearl's coloring; and tiny bubbles or wrinkles in the pearl's surface. Irregularities such as these generally do not indicate a weakness in the pearl's structure (such as a crack would), and they are often so small as to be virtually unnoticeable.
