What are freshwater pearls?

So, what exactly are freshwater pearls, and where do they come from? A natural freshwater pearl is a lustrous gem produced by an oyster or other mollusc living in fresh water, like a lake.

A freshwater cultured pearl is produced in the same way as a natural freshwater pearl but with an extra helping hand from humans.

How are freshwater pearls made?

Let's take a look at how natural freshwater pearls are made. When an irritant gets into the shell of the oyster or other mollusc, it begins to coat it with many layers of a pearly substance called nacre, eventually creating a lustrous pearl.

Unlike a natural pearl, a freshwater cultured pearl starts with human intervention. A skilled pearl technician gently inserts an irritant into the shell of a freshwater mussel. The mussels are then put into nets and submerged in the lakes surrounding the pearl farm.

The irritant in the shell grows to form a pearl sac in which the mother of pearl (nacre) is deposited layer upon layer until a pearl is formed. The longer the molluscs are left alone, the larger the pearl will grow. A freshwater mussel can create up to 50 cultured pearls at a time.

What’s the difference between cultured and freshwater pearls?

The term "cultured pearl" means genuine pearls produced with human assistance, as described above. There are two types of cultured pearls: freshwater and saltwater.

Freshwater pearls are harvested in lakes, rivers or ponds, while saltwater pearls come from the ocean. As saltwater pearls are more expensive, freshwater cultured pearls are great for everyday jewellery.

Freshwater pearl colours

Pandora's freshwater cultured pearls are treated through bleaching or dyeing to enhance or change the colour. Once harvested, white pearls are bleached, while coloured ones are dyed. Both types undergo a lustre-enhancing treatment

The most classic pearl colour is white or ivory, but thanks to dyeing technology, we can wear pearls in an array of lustrous colours. Some pearls also display an iridescent colour phenomenon known as "orient."

How to care for freshwater pearls

Treated freshwater cultured pearls are quite soft, with a hardness level of 2.5-4 on the Mohs scale, used to rate gem hardness. Because of this, they're prone to scratching and damage from acids, solvents, ultrasonic cleaning and dehydration.

Some dyed pearls may fade or revert to their original colour when exposed to sunlight or strong light. Here are our tips to keep your freshwater pearl jewellery looking great:
