UNDERSTANDING PEARL QUALITY
Look Beyond Size.
What makes a beautiful pearl?
There is no single answer.
Luster, surface, shape, color, size and matching all influence how a pearl looks. Understanding these characteristics allows you to look beyond simple labels and appreciate what makes each pearl distinctive.
01 — LUSTER
How Light Comes Alive
Luster describes the quality and intensity of light reflected from a pearl's surface and underlying layers.
A pearl with stronger luster can display brighter highlights, clearer reflections and greater visual depth.
For many pearl specialists, luster is one of the most important characteristics when evaluating a pearl's appearance.

02 — SURFACE
Nature Leaves Its Signature
Because pearls form through a natural biological process, their surfaces may display small dimples, ridges, spots or subtle textures.
Generally, fewer noticeable surface characteristics contribute to a cleaner appearance.
However, minor natural characteristics can also serve as a reminder that each pearl developed individually rather than being manufactured to perfect uniformity.

03 — SHAPE
Symmetry or Individuality
Perfectly round pearls have traditionally been highly valued for their symmetry.
But shape is not simply a question of better or worse.
Baroque, oval, button and other organic shapes are deliberately chosen in contemporary jewelry for their individual silhouettes and expressive character.
Round for symmetry. Organic for individuality.
04 — COLOR & OVERTONE
Look a Little Closer
A pearl's color can be more complex than it first appears.
Beyond its main body color, a pearl may reveal subtle secondary tones known as overtones.
Depending on the pearl and the lighting, whites may lean toward cream, silver or rose, while other varieties can reveal darker or warmer tones.

05 — SIZE
Presence, Not Quality
Pearl size changes the visual presence of jewelry—but larger does not automatically mean better.
Smaller pearls can create a delicate, understated look. Larger pearls naturally attract more attention.
Size should therefore be considered alongside luster, surface and overall design.
06 — MATCHING
Harmony in a Design
When several pearls appear together, matching contributes to the overall visual balance of a piece.
Designers may select pearls with similar size, color, luster and shape for consistency—or deliberately combine natural variations to create a more organic composition.
Both approaches can be intentional.
UNDERSTANDING PEARL GRADES
You may encounter grading terms such as A, AA, AAA or AAAA when shopping for pearls.
Unlike standardized diamond grading systems, there is no single universally adopted grading scale for pearls across all sellers.
The meaning of these terms can therefore vary depending on the standards used by each company.
For this reason, we encourage looking beyond a grade alone and considering the pearl's actual characteristics—including luster, surface, shape, size and overall appearance.
HOW SHELLIVA LOOKS AT PEARLS
Luster → Surface → Shape → Color → Matching
We consider the visual character of a pearl in relation to the jewelry it will become.
A pearl does not need to be perfectly identical to another to be beautiful. Sometimes harmony matters. Sometimes individuality is the point.
