What is the Difference Between Freshwater and Cultured Pearls

The main difference between freshwater and cultured pearls is the type of mussels that produces them. Freshwater pearls are formed by freshwater mussels, while cultured pearls can be produced by either freshwater or saltwater mussels.

Pearls are natural gemstones that are treasured for their beauty, rarity, and timeless elegance. There are a few types of pearls in the market as freshwater pearls, seawater pearls, and cultured pearls. The difference between these types of pearls lies in their formation.

Difference Between Freshwater and Cultured Pearls - Comparison Summary

What are Freshwater Pearls

Freshwater pearls are pearls that form in freshwater mussels. Freshwater pearls typically form in rivers, lakes, and ponds. They are often less expensive than saltwater pearls but are more expensive than cultured pearls. Freshwater pearls come in a wide range of colors, including white, cream, pink, peach, lavender, and even black. They also come in a variety of shapes, including round, button, drop, and baroque (irregular shape).

Freshwater vs Cultured Pearls

Freshwater pearls can form naturally, but the majority of freshwater pearls available today are not natural pearls. In natural freshwater pearl formation, a small irritant, such as a piece of sand or a tiny parasite, makes its way into the mussel’s shell, and the mussel reacts by producing nacre to cover the irritant. Over time, this process can result in the formation of a pearl. However, the chances of finding natural freshwater pearls are rare. This is why cultured pearls are more common in the market than freshwater pearls. In pearl farming, pearl farmers will surgically insert a small piece of tissue, called a “graft,” into the mussel. The mussel will then begin to produce a nacre around the graft, eventually forming a pearl.

What are Cultured Pearls

Cultured pearls are pearls that are grown under controlled conditions in a pearl farm, in contrast to natural pearls, which form spontaneously in nature. Cultured pearls form when farmers surgically insert a small piece of tissue (a “graft”) into the mussels, and the mussels then secrete nacre, which covers the graft and forms a pearl. The farmer then controls the pearl-formation process, which allows for a higher output and a more consistent size and shape of the pearls.

Cultured pearls can be either saltwater or freshwater pearls. Saltwater pearls, typically, grow in oysters in the sea, while freshwater pearls grow in mussels in rivers, lakes, and ponds. The process of culturing pearls is similar for both types, but the specific methods and conditions vary depending on the species of mussels and the location.

Compare Freshwater and Cultured Pearls - What's the difference?

Cultured pearls are virtually identical to natural pearls in appearance, and it is difficult to distinguish between them without laboratory analysis. The main difference between natural and cultured pearls is their formation. Cultured pearls have become increasingly popular in recent years due to their affordability and wide range of sizes, shapes, and colors, which can be difficult to find in natural pearls. Additionally, pearl farming has a lower mortality rate for mussels, and it is more sustainable than fishing for wild pearls. Overall, cultured pearls are a popular and affordable alternative to natural pearls and have become a major part of the pearl industry today.
