It's important to know the types of pearls. This applies whether you are buying jewelry or just admiring their beauty. Studying their formation, varieties, and traits will help you decide and appreciate them. 

The realm of pearls introduces you to a mixture of exciting factors: science, art, and tradition. All these factors have amazed humanity for centuries.

This guide will explain pearls. It will cover their types, traits, and differences. It will also help you choose the perfect pearl for your taste and needs.

How Pearls Are Formed

Pearl formation is a natural marvel. It begins when an irritant, like a grain of sand or a tiny parasite, enters an oyster or mollusk. The creature reacts by coating the invader with layers of nacre, a smooth and shiny material. Over time, these layers accumulate, and a pearl is formed.

● Natural Pearls: These are formed independent of interference by human beings. When an irritant naturally enters the mollusk, the formation of the pearl takes place naturally. Natural pearls are very rare and highly valued for their rarity and unique process of formation.

● Cultured Pearls: Cultured pearls are human-made. A technician places a small bead or tissue inside a mollusk. This process induces the mollusk to form a pearl. By doing so, it allows for more predictable results. Most pearls traded today are based on this method.

The way pearls are formed affects their traits and prices. Natural pearls are rare and often irregular in shape. In contrast, cultured pearls are more diverse. Controlled farming has caused a wide variation in their shapes, sizes, and qualities.

Natural vs. Cultured Pearls

A key part of selecting pearls is knowing the difference between natural and cultured ones.

Natural Pearls

They form entirely by chance in the wild, with no human intervention. It is for this reason they are so rare: they have a natural formation process. 

Natural pearls are rare and beautiful. So, they are treasured by royalty and collectors. Each pearl is truly unique. There are no similar ones in size and shape.

Cultured Pearls

These pearls are cultivated with the help of man. The implantation procedure aims to make this process more predictable. Techniques in pearl farming allow for the mass production of high-quality pearls. Thus, they are more available and diversified in style and prices.

Differences

Natural pearls are rarer than cultured pearls, which is reflected in their price. Natural pearls generally cost more. 

On the other hand, cultured pearls come in a much wider range of colors, shapes, and sizes. That's the reason most people think of pearl jewelry as an affordable everyday luxury.

Saltwater vs. Freshwater Pearls

There are two types of pearls differentiated by the environment in which they grow. These are saltwater and freshwater ones.

● Saltwater Pearls: They generally grow in ocean water. These pearls have high luster, are larger, and are rounder. Saltwater pearls, such as Tahitian, South Sea, and Akoya, are regarded as extremely valuable. The reason is their beauty and size.

● Freshwater Pearls: These are grown in lakes, rivers, or ponds. They do not have a regular shape like saltwater pearls. But they offer an amazing range of sizes and colors at very affordable prices.

Comparison of Key Traits

● Size: Saltwaters are generally larger than freshwater ones.

● Shape: Saltwater pearls are usually round. Freshwater pearls are more irregular.

● Luster: Saltwater pearls tend to have a more brilliant mirror-like luster because of the thick layers of nacre.

● Color: The color variation of freshwater pearls is natural, while that of the saltwater pearl is white, black, or golden.
