Real pearls are always colder than the surrounding temperature unless worn on the body. Even when the weather is warm, real pearls will feel cool. Fake pearls, on the other hand, will not be colder than room temperatures. This you can tell by touching them.
Further, you can go for the weight test- Real pearls are heavier. Fake pearls are lighter. The nacre that makes up the layers of a real pearl is very dense, so it will weigh a bit more than plastic or resin – the common materials used in many fake pearls.
You can also find the difference between fake and original pearl by conducting a light test - When put under light, real pearls perfectly reflect the light whereas fake pearls won’t reflect so much light. (You can see in many pictures in this website where pearls are reflecting the light, so is the reason, it is hard to get the exact color of the pearl in the pictures).
Fire test- Burn a pearl for some time and then turn it off. After wiping off the black burnt coating, you can still see the real pearl inside. A fake pearl won’t look anything other than coal after burnt.
Since pearls are rare, they are often duplicated. This is the reason why certification of is necessary while purchasing pearls
