Pearls are beautiful and valuable, but how can you tell if they're real? Real pearls are formed naturally inside mollusks, whereas fake pearls are man-made beads, often crafted from glass, plastic, alabaster, or shells coated with a pearlescent finish. Several tests can help distinguish real pearls from their faux counterparts, including examining the drill holes, comparing weight, feeling for coolness, and the tooth test. Let's explore these methods to become pearl experts!
| Characteristics | Values |
|---|---|
| Temperature | Real pearls feel cool to the touch before warming up. Plastic pearls are about room temperature and warm up more quickly. |
| Weight | Real pearls are heavier than fake ones. |
| Drill holes | Real pearls have sharp, well-defined edges around the drill holes. Fake pearls have rough or rounded edges, and the coating around the drill holes may chip or peel away, revealing the plastic or glass bead within. |
| Surface | Real pearls have tiny irregularities and ridges on the surface. Fake pearls are smooth and polished. |
| Texture | Real pearls feel gritty or sandy, whereas fake pearls are smooth. |

The 'tooth test': real pearls feel gritty, fakes are smooth
The tooth test is a simple and quick way to tell real pearls from fakes. It involves holding one or two pearls between your thumb and forefinger and gently rubbing them against the biting edge of your front teeth. This test is based on the fact that real pearls will usually have a slightly rough or gritty texture from tiny, scale-like imperfections in their outer layers of nacre. On the other hand, fake pearls made from glass or plastic will typically be almost perfectly smooth.
It is important to note that this test may not always be accurate. For instance, cultured pearls may feel smooth because they have fewer nacre coatings. Similarly, an original dyed pearl will also feel smooth because the dye fills in the indentations on the pearl's surface. Therefore, it is recommended to use other tests in conjunction with the tooth test to make a more definitive judgment.
One additional test is to examine the pearls under magnification. Real pearls will have tiny irregularities and ridges on their surface, whereas fake pearls will have a smooth coating. Another test is to feel for coolness to the touch. Real pearls will initially feel cool to the touch before warming up against your skin, whereas plastic pearls will be at room temperature and will warm up more quickly. However, it is important to note that high-quality fake glass pearls may also feel cool to the touch, so it is essential to verify the results with other tests.
Furthermore, you can inspect the drill holes in the pearls. Real pearls usually have sharp, well-defined edges to the holes, resembling a hollow cylinder. In contrast, fake pearls often have rough or rounded edges, and the coating around the drill holes may be thin and appear like shiny paint. Over time, this coating may chip or peel away, exposing the underlying plastic or glass bead. By examining these characteristics, you can gain additional insights into the authenticity of the pearls.

Real pearls are heavier than plastic imitations
One of the key ways to tell real pearls from plastic imitations is by feeling their weight. Real pearls are normally heavier than their fake counterparts. Gently toss them up and down in your hand and pay attention to how they feel. This method works for both plastic and glass bead imitations. However, it's important to note that solid glass beads can be heavier than natural or cultured pearls, so other tests should also be used.
Plastic imitations tend to feel light, even lighter than waxed glass beads. This is because they are made from plastic beads coated with a synthetic blend, lacquer, or other cheap materials. The composition of imitation pearl beads includes powdered shells, giving them a density similar to that of genuine pearls.
Another way to test the authenticity of pearls is to examine the drill holes. The holes in real pearls are usually very small and have sharp, well-defined edges. In contrast, imitation pearls often have larger holes with rough or rounded edges. Over time, the artificial coating around the drill holes of fake pearls can wear away, exposing the plastic or glass bead within.
To further distinguish real pearls from plastic imitations, you can try the tooth test. Gently rub the pearl against the biting edge of your front teeth. A real pearl will feel slightly gritty or rough, while plastic imitations will feel smooth and glassy. This test is based on the fact that natural pearls accumulate layers of nacre with slight irregularities, resulting in an uneven texture.

Real pearls have well-defined drill holes, fakes have rough edges
One of the ways to tell real pearls from plastic imitations is to examine the pearls' drill holes. Real pearls usually have well-defined drill holes with sharp edges, resembling a hollow cylinder. On the other hand, fake pearls often have rough or rounded edges around their drill holes. The coating around the drill holes of imitation pearls is typically thin and shiny, resembling paint that can eventually peel off.
The drill holes in real pearls are usually small, while those in fakes are often larger. The larger drill holes in fake pearls may be due to the need to cover the inner glass or plastic bead with enough coating to mimic a real pearl. However, this thicker coating can also make the drill holes more susceptible to chipping and flaking over time.
When examining the drill holes, you may also notice that fake pearls have uneven material buildup around the holes. This buildup is usually composed of the acrylic paint used to give the inner bead its iridescent, pearly coating. In some cases, you may even see slivers of the underlying glass or plastic bead, further indicating that the pearl is a fake.
It is important to note that old and well-worn real pearls may also have rounded edges to their drill holes. Therefore, it is recommended to use this drill hole examination in conjunction with other tests, such as the tooth test or weight test, to conclusively determine whether a pearl is real or fake.

Real pearls are cool to the touch, plastic imitations are room temperature
Real pearls are formed naturally inside mollusks. They are heavier than fake pearls, which tend to feel light. Fake pearls are often made from plastic, glass, alabaster, or shells coated with a synthetic blend to give them a similar appearance to real pearls.
One of the ways to tell real pearls from plastic imitations is by touch. Real pearls are cool to the touch for a few seconds before warming up against your skin. Plastic imitations, on the other hand, are at room temperature and do not have the same cool feeling when touched. However, it is important to note that fake pearls made of glass beads can also feel cool to the touch initially, but they take longer to warm up compared to real pearls.
To perform a touch test, hold the pearls in your hand and focus on how they feel against your skin. Real pearls should feel noticeably cool, similar to stepping barefoot onto a marble floor. Plastic pearls will be at room temperature and will warm up more quickly. It is recommended to verify the results of this test with other methods, as it may not always be accurate.
Another way to distinguish real pearls from plastic imitations is through their weight. Real pearls tend to be heavier than fake ones, so you can gently toss them in your hand to feel the weight difference. However, this weight test may not always work, as some high-quality imitation pearls made from glass beads can weigh almost the same as real pearls.
In addition to the touch and weight tests, there are other methods to differentiate real pearls from plastic imitations. One method is the tooth test, where you gently rub the pearl against your front teeth. Real pearls will feel slightly gritty or rough, while plastic imitations will be almost perfectly smooth. Another method is to examine the drill holes in the pearls. Real pearls usually have sharp, well-defined edges around the holes, while fake pearls may have rough or rounded edges. Additionally, you can look for chipped paint or coating around the drill holes, as fake pearls may have uneven material buildup due to the artificial coating wearing away.

Real pearls have surface irregularities, fakes are smooth
Real pearls are formed naturally inside mollusks, whereas fake pearls are man-made beads. The natural formation process of real pearls results in small irregularities and ridges on their surfaces, making each pearl unique. In contrast, synthetic pearls are manufactured to have a much smoother and plastic-like feeling.
The surface irregularities of real pearls can be observed under magnification or by looking for slight differences between pearls in a strand. These differences can include variations in shape, size, colour, and surface characteristics. On the other hand, fake pearls are often identical in these aspects, indicating they are probably imitation.
One simple way to identify the surface irregularities of real pearls is to rub them against your front teeth. A real pearl will feel gritty, sandy, or slightly rough due to the tiny scale-like imperfections in its outer layers. In contrast, fake pearls made from glass or plastic will usually feel almost perfectly smooth. However, it is important to note that cultured pearls may feel smoother because they have fewer nacre coatings, and this test may not always be accurate.
Another method to identify surface irregularities is to rub the pearls against each other. Real pearls will generate a slight friction due to their outer layers not being perfectly smooth. Fake pearls, on the other hand, often have smooth coatings and will glide past each other.
