What determines the value of a pearl?

  1. Luster – The most important of all value attributes in a pearl is luster. Luster is defined as the quality and quantity of light reflecting from the surface or from under the surface of a pearl.
  2. Shape – Pearls come in a wide variety of shapes but in most circumstances, the more round the pearl, the higher the value.
  3. Colordepth and consistency of color in the body of the pearl
  4. Sizepearls are measured in millimeters. When the other value factors are equal within a pearl type, the larger the pearl, the higher the value.
  5. Surface QualityThe cleaner the surface of a pearl (fewer bumps, marks and dull spots) the more valuable the pearl.
  6. Matching abilityequality or unity of pearl size
  7. Nacre thicknessThis is only relative to bead-nucleated pearls as non-beaded (freshwater pearls and keshi pearls) are 100% nacre. The thicker the nacre and regularity of its layers in a saltwater pearl, the more valuable a pearl. If the pearl does displays a chalky or dull appearance, the nacre is too thin.
