Start by choosing a pearl type for the color, size and look you want, then compare individual pearls by luster, surface quality, shape, size, nacre quality and matching. Freshwater, Akoya, Tahitian and South Sea describe different cultured pearl origins and appearances; they are not a simple quality ladder. Ask what the pearls are, how they are matched and what a grading or identification document actually covers.
Pearls are easiest to compare when you separate type from quality. Type tells you what kind of pearl you are looking at; the individual pearl’s luster, surface, shape, size, nacre and matching determine whether that particular piece suits your budget and taste.
Compare the main cultured pearl types
Freshwater: These span a broad range of shapes and colors. Compare luster, surface and how consistently a strand is matched.
Akoya: Often round, with bright, sharp luster. Compare surface cleanliness, roundness and matching.
Tahitian: Natural dark body colors can show overtones. Compare color, luster and visible blemishes.
South Sea: Often larger pearls in white, silver or golden hues. Compare size, luster, surface and strand consistency.
These are typical descriptions, not guarantees for every pearl. Natural pearls and cultured pearls are different categories; most contemporary pearl jewelry uses cultured pearls.
Use quality factors instead of retail grades
GIA identifies seven value factors: size, shape, color, luster, surface quality, nacre quality and matching for jewelry with multiple pearls. No one factor answers every buyer’s question. A round, evenly matched strand may matter more to one shopper, while another may prefer a distinctive baroque shape or unusual color.
Look at pearls under neutral light and ask for a clear return policy. For a strand or pair of earrings, compare the pearls together, not just one close-up image. Be cautious when a listing says only “AAA” without explaining who assigned the grade and what the label means.
Choose the piece you will wear
A classic matched strand prioritizes consistency. A pendant or single-pearl earring puts more attention on one pearl, so its surface and luster become easier to see.

Common questions
Are freshwater pearls lower quality than saltwater pearls?
Not automatically. Pearl type describes origin and typical appearance. Compare the individual pearls for luster, surface, shape, size, nacre and matching instead of treating type as a grade.
What does AAA mean on a pearl listing?
Retail grading labels are not a universal standard. Ask the seller to explain its scale and compare visible quality factors; GIA describes pearls using its value factors rather than a universal retail letter grade.
Which pearl type should I choose for a first necklace?
Choose by the color and scale you will wear. Compare freshwater and Akoya strands for white or cream looks, and consider Tahitian or South Sea pearls when their darker or warmer colors are the priority.
