Pearl Grading

Under each pearl is a label which shows the grading for the pearl – the pearl’s shape, lustre, surface marks and size. Our grading system has both a grade for lustre and another for the marks (spots) on the surface of the pearl. This provides more information making it easier and quicker for our customers to select the pearls they require.
