   Look for minor imperfections. As noted in a higher place, real pearls are only rarely "perfect". Usually, they'll accept small blemishes or irregularities in their shape.^[1] Their outer nacre layer may also reverberate light differently on different parts of the pearl. Imitation pearls are almost ever "too perfect" — they look perfectly spherical, they have the same amount of luster on every part of the surface and show no indents or imperfections.

   Tip: While perfectly circular real pearls are rare merely possible, a necklace will almost never be made but from these types of pearls. A necklace fabricated from pearls that all seem to exist exactly the same smooth, round shape is well-nigh certainly a fake.^[2]

2. 2

   Bank check for a abrupt, good for you luster. Luster is a style that jewelers depict the blazon of lite reflected from a gem. A pearl'due south luster is part of what makes it and so cute. Good-quality pearls should have a brilliant, articulate luster that makes them smooth when calorie-free hits them. If you look closely, you should be able to see your ain reflection on the pearl's surface.^[three]

   • One problem with this test is that low-quality existent pearls (which mostly accept a deadening, "chalky" luster) can look similar to fake pearls. Bank check your results with a few of the other tests in this article.^[four]

3. 3

   Cheque for an overtone. Good-quality pearls are oft prized for their overtones — the subtle colour that is visible on their outer surface when lite hits them. Imitation pearls will usually not have this overtone effect, which is tricky to duplicate. Thus, if your pearl seems very slightly shaded with color when lite hits it, there is a skillful chance it's real. Rose and ivory are two of the near desired overtones for white pearls, though a wide variety of colors are possible, especially for dark pearls.^[5]

   • Since some real pearls don't have a visible overtone, not seeing an overtone on your pearl isn't necessarily a certain sign that information technology'due south faux.

4. four

   Await for clues around the drill hole. Pearls on a strand or necklace volition usually accept holes drilled in them for the string to pass through. Examining this hole carefully can help you lot tell whether your pearl is real or not. Specific things y'all'll want to look for include:

   • Well-defined edges to the pigsty. Real pearls usually have drill holes with sharp edges (like a hollow cylinder). Fakes often accept rough or rounded edges. However, old and well-worn existent pearls may also have rounded edges to their holes. Imitation pearls may also bow outward at the surface of the pearl, rather than being perfectly cylindrical.
   • Chipped paint or coating around the hole. Every bit fake pearls rub against each other with repeated use, their artificial blanket tin can article of clothing away around the holes. You may be able to encounter slivers of glass or plastic underneath. This is a certain sign of a imitation.

5. 5

   Expect in the pigsty for a line betwixt the nacre and nucleus. A real pearl almost always has a articulate outer nacre layer, while simulated pearls take thin layers of artificial nacre or lack them entirely. If your pearl has a drill hole, you can bank check for nacre by peering in with a magnifying glass. Real pearls will usually (simply not always) have a noticeable line that separates the nacre from the nucleus (the inside role of the pearl).

1. i

   Rub the pearls against your front teeth. Hold one or two pearls betwixt your thumb and forefinger and press them gently into the biting edge of your front end teeth. Rub them confronting your teeth with a side-to-side motility. A real pearl will normally accept a slightly rough or gritty texture from tiny scale-like imperfections in its outer layers of nacre. Fake pearls fabricated from glass or plastic will commonly be almost perfectly smooth.^[6]

   • You may desire to brush your teeth earlier attempting this test to brand sure they're clean. Food balance from a recent meal can give imitation results.

2. 2

   Rub the pearls confronting each other. Hold a few pearls in your fingers and gently rub them against each other. Experience for the slight sensation of friction. Real pearls will usually generate a footling friction when they rub confronting each other because their outer layers of nacre are not perfectly smooth.^[7] Fake pearls, on the other hand, often have smooth coatings and volition commonly glide by each other when rubbed together.

   • Have a close look at your hands after this examination. When two pearls rub confronting each other, their outer layers often erode a small amount. If you find a fine, powdery, white residual after rubbing your pearls, this is probably powdered nacre — a sign that the pearls are real.^[8]

3. three

   Cheque whether the pearls are perfectly circular. Because they're products of nature, every real pearl is slightly different, only like snowflakes or fingerprints. Nearly pearls won't exist perfect spheres — they'll usually exist slightly oblong or take pocket-sized defects. If your pearls look perfectly round to you, at that place's a good chance they're bogus.

   • Information technology is possible for real pearls to be perfectly round. However, examples of these are very rare and usually fetch a high toll.^[ix]
   • Not sure whether a pearl is perfectly round or not? Effort advisedly rolling it on a flat surface. Imperfect pearls won't consistently roll in a straight line.^[x]

4. iv

   Experience for coolness to the touch. For this test, you'll need a few pearls that have been sitting out — non ones you've been wearing. Hold the pearls in your mitt and concentrate on the mode they feel confronting your skin. Real pearls should experience noticeably cool for a few seconds before they warm upwards.^[11] The feeling is like to what you'd get from stepping barefoot onto a marble floor.

   • Plastic pearls, on the other hand, will exist virtually room temperature and will warm up more quickly.^[12]
   • Note: Good-quality false drinking glass pearls may still requite the "cool" sensation. Verify your results with other tests if this is the first one you've attempted.

5. five

   Experience the weight of the pearl in your paw. Carefully bounce ane or 2 pearls in your hand to get an thought of how much they counterbalance. Most real pearls feel somewhat heavy for their size. On the other hand, fakes (especially plastic pearls) will have a light, insubstantial experience.

   • For obvious reasons, this test isn't perfect — judging the weight of a few small pearls can exist catchy. For all-time results, yous may want to compare your pearls with a set you lot know are existent or fake. E'er verify with another test no thing how sure you are of a pearl's weight.

   Advertizing

1. 1

   Check for "scaly" surface patterning with a microscope. You tin utilise a 30x jeweler'south loupe, but microscopes with 64-power magnification or more piece of work best for this. The surfaces of real pearls take a maze-like, scaled pattern. This patterning looks a little like a topographical map. Information technology's this microscopic scaling that gives real pearls their "gritty" texture.

   • Past contrast, fake pearls will often have a surface covered with grainy, fairly regular bumps (a little like the cratered surface of the moon).

2. 2

   Compare your pearls to certified real pearls. All of the tests above are easier if you have some pearls that you know are real for comparison purposes. Try contacting a jeweler about the possibility of comparing your pearls to a set of ones that are certified existent. Alternatively, borrow a friend or relative's real pearls to make your comparisons.

   • Utilize mutual sense about the sorts of tests yous do with the certified real pearls. For case, you won't want to effort the molar test or the friction test with someone else's precious stones.

3. three

   Become your pearls appraised past an skilful. If you are having a difficult time determining your pearl's authenticity, you can always take your pearl to a reputable jeweler or gemologist. These professionals have the tools, training, and expert eyes to tell whether your pearl is existent (and, if information technology is real, how high its quality is). However, these options often don't come cheap — a basic appraisal tin can easily cost more than than $100.

4. 4

   Try ordering an X-radiograph examination. This test, which an expert may do to make up one's mind whether your pearls are real or not uses an X-ray machine. Real pearls will evidence up as a semitransparent grey color on the X-ray. Fakes will be solid white on the negative and solid blackness on the positive print.

5. v

   Try ordering a refractometer test. This advanced test measures how much light passes through the pearl to determine its authenticity. Pearls ordinarily have a refractometer reading (called a "refractive index") of betwixt 1.530 and 1.685. The difference betwixt these ii values (0.155) is called the pearl'due south birefringence, which affects the way the pearl looks in the light. These qualities tell an proficient that the pearl is almost likely a real one.

1. 1

   Beware of using simply one test to verify pearls. This bears repeating: any unmarried 1 of the tests above can sometimes produce simulated results. To be certain of your results, perform many unlike tests.

   • Equally merely one example of how isolated tests can be misleading, one source found that real pearls that take been specially polished tin can experience very smooth in the molar and friction tests.

2. two

   Avoid the "burn" exam. Some sources may recommend holding pearls in an open flame to determine whether they are fake or not. According to this rumor, fake pearls will fire or melt, while real pearls will be unaffected. The truth is more complicated. While most simulated pearls volition be damaged by fire, so volition some real ones. Real pearls that have been processed with an artificial outer coating are especially vulnerable to flame and tin can suffer from blemishes, deformed drill holes, and ruined luster afterwards but a few seconds in a flame.

   • In addition, it'due south worth noting that pearls conduct heat well and can become very hot when heated over an open flame. If you do endeavour this test, accept all necessary precautions to avoid bad burns.

3. 3

   Don't fall for simulated pearls sold with exotic names. If a seller is trying to sell you on a pearl's proper noun rather than its physical qualities, you may exist getting ripped off. For example, "Mallorca" (or "Majorca") pearls, which are named after the exotic Mediterranean island of Mallorca but are entirely man-fabricated, are sometimes sold to unsuspecting costumers.

4. iv

   Don't ignore common sense instincts about a pearl'southward price. The price of a existent pearl will vary greatly based on its size, shape, overtone, and other features. Notwithstanding, they volition never be outright cheap. For example, a necklace made from freshwater pearls (the cheapest variety of real pearls) can easily retail for several hundred dollars. If a seller is giving you a deal on a fix of real pearls that seems also good to be true, it probably is.

   • As a full general rule, y'all'll only want to buy pearls from licensed, certified jewelers and pearl retailers. Buying pearls from street vendors or pawnshops can be a risky proposition. Encounter our pearl-buying guide for specific tips.
