Grade aa+
Then we have the Grade AA+ quality stamp
These pearls are a small step down the quality ladder, but but but, these pearls are still of an insanely good quality and the difference from Grade AA+ to AAA is not huge.
Here are 6 things that characterize the Grade AA+ pearl:
- The pearls are round, while some pearls can be off-round (oval-shaped).
- Very high gloss - The pearl has a very good reflection.
- The reflected light in the pearl appears bright and clear, with some blurred edges.
- The occurrence of spots on the freshwater pearl is less than 5-10% on each pearl surface.
- Strings will mostly be clean to the eye upon inspection.
- Very good matching of the pearls on the string - Little to no variation in color, tone, luster, shape or size
