Blue Pearl Grading
New Zealand Blue Pearls are graded according to size, shape, lustre and colour. Blue pearl colours range from blues, greens, golds to pinks and some have a splash of red.
There are two brands of blue pearls: the Eyris brand and the Pacific Blue brand.
Eyris Pearls, which come with a registered ID number, are divided into Select Gem, Gem or A grade. Pacific Blue are divided into B, Mystique or C grade also come with a Certificate of Authenticity. The grade given to the pearl signifies the degree of clarity, smoothness of surface and presence of concholin (a natural material which appears as dark spots).
