Physical Characteristics of Real vs Fake Pearls

Real pearls have a few telltale signs that set them apart from fakes. Let’s explore these signs:

Surface Texture

Real pearls have a gritty, uneven surface that feels slightly rough. Imitation pearls are too smooth and flawless. Run your fingers gently over the pearl - if it's perfectly smooth, it's likely not the real deal.

When held up to light, a real pearl gives off a soft, warm glow. Fake pearls have an unnatural sheen that looks glassy. Real pearls also have depth to their luster - they seem to glow from within. Imitations have a surface-only luster.

Natural pearls develop over time within oysters, so real pearls often have slight natural imperfections and asymmetries. Fake pearls aim to look too ideal, so they appear too round and flawless. Check for natural-looking ridges or dips in the pearl's surface.

Hold the pearl up to a light source. Real pearls have a translucent, milky quality that allows some light to pass through. Fake pearls appear opaque or don't allow light through at all.


Due to their organic nature, real pearls feel slightly heavier than imitations of the same size. Real pearls are solid nacre, while fakes are hollow or lighter materials. So trust your instincts - if it feels too light to be real, it probably is.

With a little practice, distinguishing real pearls from imitations can become second nature. Apply these tips next time you're shopping for pearls and you'll be spotting the faux in no time!

Perform a Tooth Test to Check Pearl Authenticity

So you found a pearl and want to know if it’s the real deal or not. There are a few tests you can do to determine if that pearl is authentic.

Perform a Tooth Test to Check Pearl Authenticity

Perform a Tooth Test

Gently rub the pearl against the front of your teeth. A real pearl will feel gritty, while an imitation pearl will feel smooth. Real pearls are made up of layers of calcium carbonate that have built up over time around an irritant inside the oyster. This gives real pearls a slightly gritty, sandy texture. Fake pearls are made of plastic or glass and will feel perfectly smooth.

You can also try the same test with your fingernail. Gently rub and scrape the pearl with your nail to feel for that fine, sandy quality. Be very careful not to drop the pearl! This works best if you have natural nails and can detect subtle textures.

If the pearl feels perfectly smooth like glass or plastic, it’s likely not genuine. Real pearls have a slightly uneven, bumpy surface that feels slightly abrasive. Don’t get discouraged though - some high-quality fake pearls can feel quite real, so do a couple of other tests as well to confirm. With a little practice, you’ll be able to tell the difference in no time and will become a pearl authenticity expert!

Have Your Pearl Appraised by a Jeweler

The only way to know for sure if your pearl is real or simulated is to have it appraised by a certified gemologist or jeweler. They have the proper training, experience, and equipment to examine your pearl and determine its authenticity.

Visit a jeweler you trust and ask them to examine and appraise your pearl. They will check attributes like surface imperfections, luster, shape, and whether the pearl has a natural or cultured origin. Real pearls that are naturally formed in oysters will have slight imperfections and an uneven, gritty surface. Cultured pearls share these qualities but are human-made. Simulated pearls look too perfect and lack depth and luster.

Pearl Appraised by a Jeweler

The jeweler can also do an X-ray to check the pearl's nacre thickness and see if there is a bead nucleus inside, indicating a cultured or simulated pearl. They may also gently rub the pearl against the edge of a tooth to feel if it's gritty like a natural pearl.

While these tests require some equipment, you can also do a few basic checks at home:

 Check for surface imperfections: Real pearls have slight surface irregularities, while simulated pearls look too perfect.

 Test if it's porous: Gently rub the pearl over your teeth to feel if it's gritty. Simulated pearls feel perfectly smooth.

  Examine its luster: Place the pearl under a strong light source. Real pearls have a depth and luster that seems to glow from within. Simulated pearls have a glassy, artificial sheen.

 Check its shape: Most real pearls are not perfectly round. Cultured pearls can be quite symmetrical, but may still look slightly uneven or lopsided. Simulated pearls are too evenly rounded.

 Test if it's weighty: Due to their organic nature, real pearls feel heavier than simulated pearls of the same size. Heave the pearl in your hand to understand its weight and density.

 Hold a match flame up to the pearl: A real pearl will not melt, while a simulated pearl's surface may burn, blister, or crumble. Be very careful, as this test can potentially damage the pearl.

For the most accurate assessment, your jeweler is your best resource. They have the proper expertise and tools to determine if your pearl is the real deal or an imitation.
