They shine under every light, providing endless glow and sophistication. They are iridescent, lustrous and simply alluring. Fact is, the beauty of a natural pearl is simply mesmerizing. While most precious gems are formed in the ground, surrounded by rocks, pearls are the only gemstone created inside a living creature – which adds to their magical, enigmatic appeal. Fact is, the gems of the seas, aka pearls, are incredibly unique gemstones. But how are pearls made? Read on to find out everything you need to know about the pearl formation of natural and cultured pearls.
Pearl Formation – Frequently Asked Questions:
A pearl is created when an irritant finds its way into an oyster or mollusk (either naturally or with human intervention). The oyster or mollusk starts secreting a fluid in order to coat the irritant. This coating later becomes a pearl.
Producing a pearl can take a very long time. The actual duration of forming a pearl ranges from 6 months to several years. Prior to producing a pearl, a mollusk needs to mature in order to begin the pearl making process.
A pearl has the same composition as the shell / nacre (mother of pearl), meaning calcium carbonate (aragonite or aragonite mixed with calcite). These are found in minute crystalline form, deposited in concentric layers.
Imitation pearls are man-made beads that resemble pearls in appearance, crafted from glass, shells or plastic. Cultured pearls and natural pearls are both considered real pearls, as they are produced by oysters and mollusks. While natural pearls occur naturally, cultured gems are farmed in pearl farms, meaning that were not formed by nature alone. A natural pearl and a cultured pearl are indistinguishable from each other.
Where Do Pearls Come From?
The simple answer to the question ‘how are pearls made’ is ‘nature’. But where do pearls come from? They are grown inside aquatic creatures – oysters and mollusks. Oysters are a specific type of mollusk that lives in the ocean (producing saltwater pearls like Akoya, Tahitian and South Sea Pearls), while mollusks live in fresh water and produce Freshwater pearls. Pearls form over a period of many years, reaching almost-round (baroque) or round pearl shapes.

How Is a Pearl Formed?
Pearls are made when a small irritant finds its way inside an oyster or mollusk. This can be a grain of sand or a piece of shell but is more typically a little parasite. This irritant bothers the mollusk, which then slowly secretes nacre to protect itself. Nacre is the substance that coats the inside of an oyster or mussel’s shell. The nacre coats the irritant, and the layers build up over time forming a pearl inside the oyster shell.
Depending on the size and shape of the irritant, the resulting pearl can take on a wide variety of sizes and shapes. The pearl color can also vary based on the part of the ocean or body of water where the mollusk lives. The ideal pearl is perfectly round and luminous. Very often they can also come in unusual shapes and different colors.
It takes many years for enough nacre to build up for the pearl to be finished. Generally, wild pearls take at least seven years to form.
Cultured Pearls: How Are Pearls Formed?
When talking about cultured gems, the question remains: how are pearls formed? Because it takes so long for a pearl to form, and they can be very difficult to find in the wild, most pearls on the market today are actually farmed. Farmed pearls are created the same way as naturally occurring pearls. The only difference: the farmer has more control over the finished product. They intentionally insert an irritant and then make sure the mollusk is living in an environment where it will secrete nacre in the correct pearl color. Cultured pearls usually take about three years to form, since the farmer will insert a larger irritant as the “seed” that would exist in the wild.
Freshwater cultured pearls are farmed pearls which are highly popular and affordable, both the round pearls and the baroque pearls varieties. But how is a pearl formed? In the same way, the freshwater mussels are surgically implanted with many tiny pieces of mantle tissue (a pearl farming process called nucleation). After the nucleation, a sac forms and cells start secreting nacre, forming a pearl.
Pearl earrings are considered one of the most popular types of pearl jewelry and it’s easy to understand why. Despite their simplicity, they complement a wide variety of outfits and add the perfect dash of sophistication. Make pearls the highlight of any look by opting for premium gems.
