If you’ve ever looked into pearl grading and found yourself confused, you’re not alone, and the problem isn’t you. Blame it on the system or, more specifically, the lack of one.
Whereas many consumers are familiar with the Gemological Institute of America’s International Diamond Grading system which standardizes the grading of diamonds by the 4Cs (cut, clarity, color and carat), there is no such institution for pearls. Further complicating matters, pearls are valued by seven qualities: luster, surface quality, size, shape, color, nacre thickness and matching. That means there’s even more room for subjective opinions.
Bearing all that in mind, 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.
Since we’re talking about grades, let’s use a simple analogy: Imagine taking a single-question test in school. You give the exact same answer to a dozen teachers and you get back … a dozen different grades! Some use letter grades ranging from A to AA to AAA to AAAA, some use numbers, some even use words they’ve cooked up, but each teacher assigns a different, arbitrary grade—to the exact same answer.
No wonder you’re confused.
How does this happen among pearl sellers? When pearls are purchased wholesale, a range of quality and price is always presented. Companies determine which pearls fall into their respective grading categories. One company’s AAA grade can be another's A 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 what another seller would even carry.
Once you understand this about pearl grading, the letters matter a lot less than the person assigning them. Look at a company’s reputation, how long they’ve been buying pearls, and whether they can explain what they see in a particular strand. Ask where their pearls come from and whether you can see the actual piece you’ll receive. Those answers will tell you more than an AAA label ever could.
I’ve been buying pearls since 1996, working directly with growers and producers around the world. Hisano and I select and grade pearls together, and she oversees design as Pearl Paradise’s Chief Creative Officer. If you want to understand the difference between two strands, book a virtual appointment. We can show you the actual pearls side by side and explain what we see.
When you own pearl jewelry that meets our standards, you can be confident that you own true quality and value.
