How much does a real pearl necklace cost?

A real pearl necklace can cost between $100 and $100,000—sometimes even more depending on when it was made. Pearl price is typically dependent on both the type of pearl (freshwater, Akoya, South Sea, to name a few) and the designer. If you're buying a strand of pearls from an established jewelry house, they will likely be on the more expensive end of the spectrum.
