PEARLY LUSTRE GRADING
The following Pearly Lustre Pearl Grading System will help you make a better choice of Pearl Jewelry.
The most important thing to understand is that each company has a different grading system
Every company in the world that grades and sells pearls uses their own system that each devised and created. Every system is subjective and every system is unique.
Pearly Lustre is using a higher quality standard as compared to Gemological Insitute of America (GIA) and the Pearl Science Laboratory Japan (PSL) pearl grading system.
Pearl Inspection Criteria
In order to help customers to compare and understand what they are paying for, Pearly Lustre has created an easy to understand pearl grading system.
There are in total 6 inspection criteria that are easily applied and guarantee meticulous quality identification. They are COLOR, SIZE, SHAPE, SURFACE PERFECTION, LUSTRE and MATCHING ATTRUBUTE.
The 6 Inspection Criteria
A pearl’s COLOR is determined by body color, accompanying color and halo. Usually, the overtone of the pearl doesn’t affect its price. However for golden south sea pearls, a darker base color would fetch a higher price.
SIZE however, plays a role in the pearl’s price tag. It is measured by considering the diameter of the pearl. In general, a bigger pearl is more expensive.
For SHAPE, round is the most desirable and proportionally the most expensive.
SURFACE PERFECTION is the degree of smoothness and cleanliness, determined by the size and location of flaws on the surface of pearls. GIA allows a light blemish on a hidden area for top grade pearls.
LUSTRE refers to the intensity of the reflected light and the clarity of the image on its surface.
MATCHING ATTRIBUTE is the degree of coordination between pearls in terms of shape, gloss, finish, colour and size.
