Luster

The luster is the shininess of the pearl included the highest luster, the shape and the reflection in the pearl.

Nacre Thickness

The nacre thickness will be inspected for pearls grading. If Pearls are with nacre thick than core nuclei that can be marked a grade high.

Blemishes

Since pearls are naturally formed, it is normal that a pearl may have some forms of imperfection. Of course, the fewer spots or lumps that a pearl has, the higher cost of the pearls.
