With the pearl jewelry market flooded with imitations, knowing how to identify authentic pearls has become essential for any jewelry buyer. Fake pearls can look convincing at first glance, but with the right knowledge, you can easily distinguish genuine pearls from imitations and protect your investment.
The Most Reliable Tests to Identify Real vs Fake Pearls
1. The Tooth Test (Most Effective Method)
The tooth test is the most reliable way to identify real pearls. Here's how to do it:
- Gently rub the pearl against your front teeth
- Real pearls: Feel gritty, rough, or sandy due to their natural nacre layers
- Fake pearls: Feel completely smooth like glass or plastic
Important: Use clean teeth and be gentle to avoid damaging the pearl's surface.
2. Visual Inspection Under Light
Examine the pearls carefully under good lighting:
- Real pearls: Show natural variations in color, slight imperfections, and lustrous depth
- Fake pearls: Look too perfect, uniform in color, with artificial shine
- Surface texture: Real pearls have tiny ridges and bumps; fakes are perfectly smooth
3. The Weight Test
Real pearls have noticeable weight due to their dense nacre layers, while fake pearls made from plastic or hollow glass feel surprisingly light.
4. Temperature Check
Touch the pearls to your skin:
- Real pearls: Feel cool initially, then warm up to your body temperature
- Fake pearls: Quickly match your body temperature
Advanced Methods for Pearl Authentication
The Drill Hole Examination
If the pearls are strung, examine the drill holes closely:
- Real pearls: Clean, precise holes with visible nacre layers
- Fake pearls: Rough holes that may show underlying material or paint chipping
The Bounce Test
Drop the pearl from about 24 inches onto a hard surface:
- Real pearls: Bounce several times due to their dense structure
- Fake pearls: Bounce once or roll away
Common Types of Fake Pearls to Watch Out For
Glass Pearls
Made from glass beads with pearl coating. They're heavier than plastic but lack the gritty texture of real pearls.
Plastic Pearls
Lightweight and perfectly round. They feel warm to touch and completely smooth against teeth.
Shell Pearls
Made from crushed shells and can be tricky to identify. They may pass some tests but lack the depth of luster found in genuine pearls.

- Extremely low prices for "high-quality" pearls
- No certificate of authenticity from reputable sellers
- Overly bright, artificial-looking luster
- Smooth texture when rubbed against teeth
- Very light weight
- Paint or coating visible around drill holes
