Pearl Colour

Qualities of Pearls - Colour

One of the most unique qualities of a pearl is its colour.

At Winterson we grade the colour of the pearls in our jewellery with the GIA Pearl Description System.

The main bodycolour of a pearl will be described, with a note also being made if the pearl has an overtone colour or an iridescent rainbow effect. We will always disclose whether a pearl has been treated for colour.

The table shows the different Colour characteristics that may be displayed by a pearl.

Bodycolour The dominant, overall colour of a pearl
Overtone Some pearls may display one or more additional overtones of colour in the reflection near the top of the pearl
Orient The rainbow colours that are displayed just below the surface of a pearl, usually those of a baroque shape, as it is rotated
