How to Spot Real Pearl Jewelry

Pearls are one of the most beloved and beautiful jewelry items to purchase for yourself or a loved one. Their history dates back thousands of years, and historians know that Chinese Royalty presented them as gifts as early as 2300 BC. 

Ancient Romans considered pearls a status symbol, so much so that Julius Caesar passed a law stating that only the ruling class could wear pearls. Thankfully, no such law exists today, and everyone can enjoy the beauty of pearls. 

Unfortunately, it can sometimes be hard to spot natural pearls from fake ones. The last thing you want is to spend your hard-earned money on pearls you thought were real, only to find out later were fake.

So, how do you spot authentic pearl jewelry? Read on to find out!

What are Real Pearls? 

To spot the difference between real and fake pearls, it first helps to know what naturall pearls are. Pearl-bearing oysters produce natural pearls in fresh saltwater. These gems can either be cultured or appear naturally, depending on how much human intervention is involved. 

Truly natural pearls formed with no human intervention are scarce and not commercially viable. Therefore, you’ll likely only find them in museums. This is why most people buy cultured pearls, which are still authentic but are produced with some human intervention. 

To produce cultured pearls, someone needs to insert an irritant inside a mollusk (oyster). The oyster will release fluid as a defense mechanism to coat the irritant, which will later form a pearl. 

What are Fake Pearls?

On the other hand, fake pearls are entirely manmade. They’re typically made from plastic, alabaster, glass, or shells with a pearly coating, so they look similar to natural pearls. 

While it’s easy to spot some fake pearls, others can look very similar to the real ones. The most well-known fake pearl, the Mallorca pearl, can often trick your eyes. 

Know the Characteristics

Naturall pearls and fake pearls can look very similar to the untrained eye. Here are some of the characteristics to watch out for:


Natural pearls have an irregular shine, whereas fake pearls have a uniform glow. This is because natural pearls are made from mollusks, which have slight imperfections that result in irregular luster. 

While the luster is irregular, it’s much deeper on natural pearls than on fake ones. Fake pearls only have a surface shine, and their luster doesn’t have any depth.

Another way to decipher if your pearls are natural is to check the temperature. Real pearls are cold for the first few seconds when you touch them, whereas fake pearls have the same temperature regardless of touch. 

However, if the fake pearls are made of glass beads, they can be cold to the touch at first. However, they tend to take longer to warm up against your skin than natural pearls. 


In addition to the luster being irregular, there are other irregularities you can watch out for when trying to spot natural pearls. For example, fake pearls will all be the exact size and shape. Additionally, they won’t have any blemishes or imperfections on them. 

On the other hand, natural pearls have some imperfections, although minuscule. You’ll also see some shape irregularity with natural pearls. Often, you’ll need to look at the pearls under a microscope to notice these imperfections. 

The Color 

Natural pearls tend to have an overtone to them. In other words, there’s a translucent pink/green hue that appears on the surface of the pearl. 

If you purchase high-quality pearls, the translucent color will be especially noticeable. However, some natural pearls don’t have an overtone, so make sure you still pay attention to the other characteristics. 


Another thing you want to consider is the weight of the pearls. Natural pearls tend to be heavier than fake ones. If you toss a set of natural pearls and fake pearls in your hand, you’ll definitely be able to notice the weight difference. 

The only case in which fake pearls may weigh more is if they’re made from solid glass beads. Glass bead pearls will actually weigh more than natural pearls, so as we mentioned above, make sure to pay attention to the other characteristics.

Drill Holes 

The drill holes in natural pearls tend to be very small, whereas they’re large in imitation pearls. If you put the pearls under a magnifying glass, you’ll notice that the coating around the drill hole of a fake pearl is typically thin, and it often resembles shiny paint. 

Sometimes, you can also see chipped or flaked coating around the drill hole that eventually peel off. 

The Tooth Test

While it may sound odd, there’s a tooth test you can do to figure out if your pearls are natural. All you need to do is take the pearl and rub it against the surface of your tooth. 

If the pearl is real, you’ll feel a grittiness similar to sandpaper. If the pearl is fake, it’ll feel as smooth as glass against your tooth. If you don’t want to rub a pearl against your tooth, you can also rub two pearls against each other to check.
