HOW TO TELL IF YOUR PEARLS ARE REAL



Have you ever wondered if the beautiful pearl necklace your grandmother gave you is the real deal? How about that gorgeous strand of pearls your boyfriend gifted you – could they be a fake? Read on to find out how to tell if your pearls are real.



1. CHECK FOR FLAWS


One way to tell if pearls are real is to examine their surface. Like everything else Mother Nature creates, no two pearls are identical. Looking closely, you'll see small ridges on real pearls resembling fingerprints. These ridges give each pearl its unique character and make authentic pearls slightly rough to the touch. Therefore, if you can't feel the ridges on the surface of "real" pearls because they're completely smooth, they probably aren't real.



2. USE NATURAL LIGHT


Authentic pearls have a radiant appearance and are more reflective. Test your pearls by holding them up to a light source and check to see if each pearl reflects light with an iridescent glow. If each pearl does, you're probably staring at a strand of authentic pearls. On the other hand, synthetic pearls have a glossy finish but aren't reflective.



3. CHECK FOR OVERTONES


Another way to tell if pearls are real is by checking for overtones (normal in real pearls) — the slight color visible on their outer surface when light hits them. As authentic pearls come from different mollusks and often from different places, the overtones of organic pearls should differ. Typically, the overtone effect—challenging to replicate—is not present in faux pearls.



4. CHECK THE SIZE


Authentic pearls come in different shapes and sizes, unlike man-made pearls (which are one uniform size). These different pearl shapes and sizes result because genuine pearls occur naturally, and anything that occurs in nature organically will show variations in form. We repeat, natural pearls are not perfectly round.


In contrast, because of its exact manufacturing procedure, faux pearls have an excessively perfect round shape. Round pearls of the same size are typically artificial. Round pearls of varying sizes, however, may be genuine.



5. CHECK THE TEMPERATURE


Another way to tell if pearls are real is with touch. Real pearls are cold to the touch. Regardless of the weather, they slowly warm up as you wear them. On the other hand, imitation pearls are warm to the touch and don't change temperature. So if you're feeling a cold sensation when you wear your pearls, they're likely real.


However, this test is not 100% accurate and greatly depends on the faux pearls' composition.



6. CHECK THE WEIGHT


Are real pearls heavy or light? Yes, one major difference between authentic pearls and fake pearls is their weight. Legitimate pearls are solid and substantial, making them heavier than their faux counterparts.


Try this pearl test; hold a loose pearl in your hand and feel its weight. If a loose pearl is light in proportion to its size, it is probably an artificial stone. Faux pearls usually consist of plastic or another type of lighter material.



7. BOUNCE IT


The bounce test is a great way to tell if you have a genuine pearl. Drop the loose pearl from 2 feet high on glass, then observe the height of the rebound. If the pearl bounces back higher than 1 foot, it is most likely a genuine pearl, as the rebound height of fake pearls is much lower.



8. RUB IT


The next method for discovering the origin of your pearls is a little invasive, but it is 100% accurate. So try this trick, rub a genuine pearl against another authentic pearl. This rubbing action should feel gritty, not smooth, and produce a thin pearl powder.


If your pearls are fake, the rubbing will have no effect. The pearls won’t produce any powder, and you might even end up with a couple of scratched plastic pearls!



9. LISTEN TO YOUR PEARL JEWELRY


Another easy way to test out your pearls is by listening to them! Knock two genuine pearls against each other, and you should hear a soft and unique sound. In contrast, when you knock counterfeit pearls together, this produces a very faint sound.



10. USE UV LIGHT


UV light is a great option if you're looking for a quick and easy way to test whether pearls are real.


Real pearls will display fluoresce under ultraviolet light, meaning they glow. Press a small UV flashlight over a pearl to see if it glows. If the pearl glows, it's likely a real pearl. A natural pearl displays fluoresce under ultraviolet light because of the presence of natural organic compounds in its nacre.


On the other hand, imitation pearls are typically made out of glass or plastic and don't contain these natural organic compounds. As a result, they won't display fluoresce under UV light. So, if you shine a UV light over an imitation pearl and it doesn't glow, it's likely a fake pearl.


UV light to test if pearls are real is that some fake pearls on the market contain materials that do display fluorescence under UV light. So, this method isn't foolproof.

 


11. NATURAL PEARLS ARE ATTRACTED TO MAGNETS


The easiest way to check whether your pearls are real or fake is by using the magnet test. If you place a small magnet near a real pearl, attraction causes the real pearl to stick to it, while fake pearls will not show any sign of attraction to the magnet.



12. FAKE PEARLS ARE CHEAP, SO CHECK THE PRICE


If you're still unsure if you have authentic pearls, take a look at their price tag. Genuine pearls will usually be more expensive than imitation pearls. So, if you find a great deal on a cheap strand of real pearls, chances are they're not real.



13. EXAMINE THE STRING


Typically, authentic pearls connect along a silk or nylon thread. If you're examining a strand of pearls and the string is made from cotton, they are most likely not real pearls. Cotton strings are most common when stringing imitation pearls.


Natural pearls are usually connected via a silk or nylon thread because these materials are much stronger and don't damage the pearls' delicate structure. In contrast, cotton strings are never used on natural pearls because they wear away the pearls' outer coating, resulting in a worn and dull appearance.



14. LOOK FOR KNOTS


Authentic pearls usually feature a knot between each pearl. These knots keep authentic pearls from rubbing against one another (leading to scratches) and protect your pearls if the strand snaps. Knots also add to the strength of the thread, so when you examine a pearl strand for authenticity, be sure to check for knots.


Beware, as some high-end fake pearl strands contain knots between each pearl to pass as authentic. So this test by itself is not definite proof. If you suspect the strand is fake, use this test in combination with a few of the other tests to be certain.



15. USE A MICROSCOPE TO SPOT IMITATION PEARLS



The easiest way to tell if a pearl is real is to inspect it using a microscope, which allows you to inspect its surface under 10x magnification. Under a microscope, a real pearl appears scaly, while fake pearls frequently have a grainy texture.



16. SEARCH FOR A DRILL HOLE


Check the pearl with a magnifying glass to determine if its drill hole has a ring around it. If so, it is most likely a genuine pearl. Another thing to look out for is that drill holes in real pearls are often smaller than those in counterfeit pearls. The holes in genuine pearls are drilled as small as possible to maintain the integrity of authentic pearls.



17. THE NAIL POLISH REMOVER TEST


Using nail polish remover is one way to test if your pearls are real. First, apply a small amount of nail polish remover to a cotton ball and then lightly rub the cotton ball against the pearl. Imitation pearls will lose total luster within one minute of doing this.

 


18. USE FIRE


When you burn a real pearl mildly, the pearl remains shiny, intact, and produces no odor. An authentic pearl produces a pop sound if the flame is consistent for about 2 minutes. In contrast, when a fake pearl comes into contact with an open flame, it emits a foul stench and loses its shine.

 


19. BITE IT


If you're unsure if your pearls are real, you can always test them by biting them. Real pearls should be quite hard, while fake ones will usually be much softer. So, go ahead and give it a try - just make sure you don't bite too hard, or you might end up with a mouthful of powder!


Gently place the pearl between your teeth and see if it feels gritty. If it does, you're most likely dealing with a natural pearl. Imitation pearls usually consist of glass or plastic, which feel smooth when you bite them.



20. USE BLACK LIGHT


The black light test is especially useful if your pearl is undrilled. Under a black light, faux pearls will typically have a milky, bluish-white hue and uniformity in color. Under a black light, authentic pearls in a strand will have different color intensities from pearl to pearl and generally appear tan or yellowish.



21. CHECK WITH A PRO


If you're still unsure if the pearls in your possession are authentic, send them to a professional jeweler for examination. They can easily assist you in authenticating your pearls and provide you with a straightforward assessment of whether or not they are organic pearls.



WRAPPING UP


In the end, if you want to be sure that a pearl is real, you’ll need to take it to an expert for authentication. But luckily, before going through these steps, there are plenty of ways to tell if something looks fishy about your pearls - from taking a closer look at their surfaces and imperfections to testing their weight and resilience. So don’t worry; you won’t be stuck with a fake pearl if you know what to look out for!
