Pearls are beautiful. There are faux (fake) pearls that look stunning and real pearls that look... well... less so. So why care whether you can tell real and fake apart?
It is important to recognize real pearls if you are buying them because precious gems are a good investment. High quality genuine pearls cost considerably more than those made of glass or plastic. The best way to know how to tell if pearls are real is by becoming familiar with the characteristics of an authentic pearl.
In conclusion, these are the simplest and quickest ways to find out if your pearls are authentic or not. Both real and fake pearls are beautiful but it's important to know which type you have.
