  • Real pearls are heavier than fake pearls. Imagine you are holding a strand of little pebbles. Would your strand be about the same weight? If not, you might be holding some pearl impostors. The nacre that makes up the layers of a real pearl is very dense, so it will weigh quite a bit more than plastic or resin, two common materials used in many fake pearls. Beware! Some materials such as glass and composite, or ‘shell’ pearls (pearls made from crushed and reconstituted shell) may fool this test.

  • If your pearls are heavy, but you still suspect they may be false, chipped or cracking paint is a sure sign that your pearls are fakes. To find it, look carefully between two pearls at a drill hole. If you notice any paint is missing, or if the material from inside the pearl formed a ‘burr’ when the pearl was drilled, your pearls are probably fake. Real pearls will have a drill hole that is quite smooth and doesn’t show any chipping (unless it has been mishandled). If in doubt, ask an expert.

  • Real pearls on a strand will never be perfectly matched. Since no two pearls are identical in nature, look for minor variation in color and shape that indicate your pearls are authentic. You may need to look very closely, as high quality strands will be well matched. However, the differences will be there!

  • Size matters. Are your pearls enormous and perfectly spherical? If you paid a comically tiny price for your comically huge pearls, it’s very likely that they are fake. In nature, the longer a pearl remains within an oyster’s shell, the more likely it is to develop imperfections like dents and divots. As a result, pearls of a very large size can be extremely valuable. If your pearls fit this description, it’s likely you have a strand of shell pearls.

  • Knots are important! Real pearls will be individually knotted on a silk or microfiber strand. These knots are crucial to the longevity of your pearls. In addition to preventing each pearl from rubbing against its neighbor, the knots also protect against the loss of more than a couple of pearls, should your strand get caught on something and break. Many high-quality fakes will be knotted (such as Mallorca Pearls), but they are easy to identify when you know what to look for.

  • If your pearls have unusual coloring, they may be fake. While some real pearls are dyed for fashion or to cover up unsightly surface imperfections, good-quality pearls usually stick to colors that appear in nature. Your favorite chartreuse strand might not be the real thing, but feel free to rock that look if it suits you!

  • The temperature of your pearls can give you some hints. Real pearls often feel cool to the touch and will quickly warm to your body’s temperature when worn. Fake pearls will feel much more close to room temperature when you first pick them up.

  • Do your pearls look like soldiers in a row? If they are perfectly uniform without any differences or imperfections, it’s very likely that they were manufactured. Real pearls are born in the sea, so they grow up getting rolled around by wind and waves, and as a result, they are never, never perfect. Even ’round’ pearls will show small lumps and bumps and minor imperfections in the nacre. In the pearls of utmost quality, these may not be visible without a loupe, but they are still there. Don’t worry — these are signs that your pearl came from nature!

  • Genuine pearls appear more ‘glowy’ than ‘shiny’. Look at your pearls under natural light. Real pearls are made from layer upon layer of a material called ‘nacre’. These layers are translucent, and reflect light in such a way that a real pearl appears to have an inner glow that is almost impossible to recreate with artificial methods. If your pearls appear harsh or have an unusual brassy or metallic appearance, they may be fake.
