Unlike diamonds, pearls do not have a universal grading standard. However, the two most widely used grading systems are:
-
The AAAA-AAA System – Used primarily for Freshwater, Akoya, and Tahitian pearls.
-
The A-D System – Commonly used for South Sea pearls.
At De Blancas, we believe in offering only the highest quality pearls, which is why we have simplified traditional grading systems into just two tiers: AAAA (Top Quality) and AAA (High Quality). This ensures that every pearl we sell meets the strictest standards for luster, surface quality, and nacre thickness.

Factors That Affect Pearl Grading
1. Luster – The most important factor; the sharper and brighter the reflection, the higher the grade.
2. Surface Quality – Fewer blemishes increase the pearl’s value and beauty.
3. Shape – Round pearls are the most valuable, while baroque shapes are more unique.
4. Nacre Thickness – Determines durability and longevity.
5. Size – Larger pearls are rarer and more expensive.
6. Color & Overtone – Unique hues and overtones add to the pearl’s desirability.
