Pearl Grading
Understanding Pearl Grades
The most important thing to understand when comparing pearl grades: Every company in the world that sells pearls uses a grading system that they themselves arbitrarily created. There is no standardized system. When pearls are purchased wholesale, a range of quality and price is always presented. Buyers determine which pearls fall into their respective grading categories. One buyer’s AAA grade can be another’s A or AA grade simply because one is selecting from a more expensive, higher range of pearl. The highest-rated pearl from one seller might not meet the minimum threshold of another seller’s lowest grade—even if the presented letter grades are identical. The result of this unregulated system is sheer confusion! Once you understand this about pearl grading, the most important thing to remember when shopping for pearls is finding a reputable company, one with many years of experience and the ability to back what they sell.
