How to tell if a pearl is real

Touch and feel the temperature

Real pearls are cold to touch for the first couple of seconds before warming up against your skin.

Fake plastic pearls have the same temperature as the room temperature and you don’t feel the coolness when you touch them. However, fake ones that are made of glass beads can be cool to touch to start with. But it tends to take them longer to warm up against your skin than real pearls.

 

 

 

 

 

 

 

 

 

 

 

 

 

Look for tiny irregularities

Real pearls are only rarely "perfect". Usually, they'll have small blemishes or irregularities in their shape. In a real pearls, you can always see very tiny differences between them, even when they are top quality and well matched.

If the pearls are completely perfect and identical in terms of shape, size, colour and surface characteristics, they are probably fake.

Examine the colour 

Real pearls often have an overtone, a translucent colour that appears on the outer surface of a pearl. It is especially noticeable among fine quality pearls. You’ll see a hint of pink, green over the main pearl colour.

If you notice the pearls have only one uniform colour and are lack of depth, they are likely to be fake. But it’s worth noting that some real pearls have no overtone either.

Observe the Shape

Most real pearls are rarely round. In general, round pearls command a higher price than pearls of other shapes. But even with a strand of real pearl necklace that is perfectly round, you can still see some slight differences in their pearl shapes.

So whatever the pearl shape, if you find them completely identical, it’s probably a sign that they’re made by machines.

Rub the pearls to check surface feel

Real pearls have textured surface due to their layered nacre structure. So when you rub the pearls lightly against each other or on your front teeth, you feel a little gritty. Fake or imitation pearls, however, usually feel smooth or glassy.

You can also test by using knife to gently scrape the surface as below:

Check drill holes

In imitation pearls, you can often see flakes or chipped coating around the drill holes that will eventually peel off.
