Pearl Library
Compare pearl types, visible qualities and the words sellers use.
Use this library to separate pearl identity from appearance and appearance from personal preference. It is a comparison starting point—not a remote grading service.

What you leave with
A clearer decision,
not another list.
Compare two pearl pieces using observable factors and internationally recognised terminology—not a seller's unexplained grade.

What are you trying to understand?
Move across the four decision areas, then use the source and local-check sections to test the choice before acting.
Visible quality
Begin with lustre, surface, shape, colour, size, nacre and matching rather than one headline grade.
Pearl family
Freshwater, akoya, Tahitian and South Sea pearls differ in typical range—not in a universal good-to-bad order.
Construction
The clasp, drill holes, knots, metal and setting affect how the finished piece wears and lasts.
Verified starting points
Real places, products
and resources to use.
Five practical records selected for this page. Each one leads to the organisation, issuer, authority or business responsible for the information—not a copied listing.
Independently selected · No paid placement · Verified 8 August 2026Akoya cultured pearls
Japan · China · Vietnam
A saltwater pearl family often associated with round, white-to-cream pearls and high lustre.
Why use it
Use GIA’s characteristics as a comparison baseline, not a remote grade.
Tahitian cultured pearls
French Polynesia
Saltwater cultured pearls whose naturally dark body colours can carry varied overtones.
Why use it
Compare colour descriptions in neutral light before accepting trade names.
White South Sea cultured pearls
Australia · Southeast Asia
Large saltwater cultured pearls generally associated with Pinctada maxima oysters.
Why use it
Compare actual lustre, surface and nacre rather than size alone.
Golden South Sea cultured pearls
Philippines · Indonesia
A South Sea pearl category with yellow-to-golden colour descriptions.
Why use it
Ask whether colour is natural and whether treatment is disclosed in writing.
Freshwater cultured pearls
China · Global trade
A diverse category spanning many shapes, sizes, colours and nucleation methods.
Why use it
Do not treat freshwater as a single quality tier; compare the individual pearls.
A listing confirms a useful official starting point—not a recommendation, test result or guarantee. Availability, prices, access, certification and operating status can change; recheck the linked source before booking, buying or travelling.

Verify before you act
Ask the seller to write down pearl identity, treatments, dimensions, metal and return terms. A page cannot grade the piece in your hand.
