What is a Pearl? A Detailed Look at the Gemstone

For thousands of years, people throughout the world have treasured pearls. Despite the long history of the gemstone and the great popularity it has today, many people may be wondering, what exactly is a pearl? Though in modern times the gemstones are primarily regarded for their one-of-a-kind beauty, pearls have had many special meanings in various ancient civilizations. Some of these meanings continue to attribute pearl, especially for people born in June, the month which pearls are a birthstone for.

Today, pearls are considered one of the most popular gemstones in the world. Notable women (and fashion icons) including Princess Diana, Jackie Kennedy, and Coco Chanel all wore pearls regularly, showcasing them on the world stage in front of millions of people and helping cement the gemstone as a timeless fashion must-have.

In this article, we take an in-depth look at the gemstone, explaining how pearls are created, their history, the difference between cultured pearls and natural pearls, the different pearl types, and their symbolic meaning. As you learn more about the defining characteristics of the gemstone, you’ll realize just how special these gemstones are.

How are Pearls Created?

Pearls are created by mollusks such as oysters and mussels in rivers and oceans throughout the world. The pearl formation process begins when an irritant gets trapped inside the shell of a mollusk. To protect itself, the mollusk begins to cover the irritant with a crystalline substance known as nacre. After applying thousands upon thousands of layers of nacre over a period of a few years, a pearl begins to develop. Nacre is also referred to as mother-of-pearl and is also seen on the iridescent inside lining of shells on pearl-producing mollusks.

The History of Pearls

It’s believed that humans first discovered pearls in coastal areas while searching for oysters to eat. Ancient Hindu texts, as well as the Koran and the Shu King (an ancient Chinese text written by Confucius), all feature many pearl references. In 2012, French scientists found a pearl that dated back to 5500BC, making it the oldest pearl ever discovered at 7,500 years old. The pearl, now referred to as the Umm al Quwain pearl, was discovered in a gravesite in the United Arab Emirates. Pearls became even more popular during the Roman Empire, though due a rule created by Julius Caesar in first century BC, the gemstones were only reserved for the society’s ruling class. This is despite the fact that only the elite would be able to afford them anyway—according to a Roman historian, a Roman general financed an entire military convoy by selling just one pearl earring.

One reason why pearls were so exorbitantly expensive was because of how rare they were. To collect pearl, divers had to plunge deep into the waters to retrieve oysters, risking their lives for a chance at finding a pearl. In addition, as centuries went on and the demand for pearls continued to rise, the population of mollusks began to dwindle. Fortunately, however, in 1893, a Japanese man by the name of Kokichi Mikimoto found a solution to the problem with the creation of cultured (or cultivated) pearls. Below, we explain the difference between natural and cultured pearls.

Cultured Pearls and Natural Pearls: What’s the Difference?

There is one key difference between cultured pearls and natural pearls, which is how the pearl development process begins. Previously, we explained that a pearl develops when an irritant becomes trapped inside the shell of a mollusk. With natural pearls, this happens by total random chance on its own in nature. For cultured pearls, on the other hand, the irritant that gets the pearl formation process started is inserted into the mollusk through a delicate precision that is performed by a pearl cultivator. Both natural and cultured pearls are considered genuine pearls. Cultured pearls are tended to by pearl farmers who create ideal water conditions for pearl development. Since the creation of cultured pearls, natural pearls have become rarer, primarily due to bans on pearl diving in many countries. As a result, natural pearls are extremely expensive, and often sold as collector’s pieces by the premier auction houses. In 2012, for example, a double strand natural pearl necklace sold at a Christie’s auction for $3.7 million. Nearly all new pearl jewelry sold today features cultured pearls. In general, cultured pearls are much more reasonably priced, though there is wide variation in the prices of cultured pearls based on many different factors, including pearl type. Below, we provide a closer look at the different types of pearls.
