Saltwater vs Freshwater Pearls

The delicious ebony Tahitian pearls from the South Pacific continue to be some of the most sought-after varieties in the world. Their luxurious dark sheen and iridescent beauty make them extremely valuable to collectors and vanguard jewelry designers. But why? What places these saltwater pearls in such high demand (making them more expensive) compared to other types of cultured pearls? And what is the distinction between saltwater vs freshwater pearls?

What Is A Pearl?

First, and in order to make the distinction, it’s important to understand just what makes a pearl. Unlike other gemstones that originate from the Earth itself, these gems (and, yes, they are considered gemstones), are made by living beings.

Cultured pearls, which are produced by an oyster (for saltwater pearls) or mussel (for freshwater versions) start with a fascinating and natural process. Because the iconic gem has become such an important part of our lives, beloved across many cultures and traditions, we humans have developed a process to help Mother Nature by increasing her yield of pearl production.

The Birth Of The Pearl

The mollusk’s implant causes it to secrete special compounds called nacre as its defense against the newly implanted irritant. Over time, layer upon layer of a nacre thickness builds up over the implanted object, and the ultimate result is what we know as a pearl.

It starts when a pearl farmer implants what the live host considers an irritant or foreign object inside its shell. The mollusk, an oyster or mussel, takes the process forward from there — with a little influence via the human interaction of implanting what becomes the early beginnings of the pearl. This is known as nucleation, which involves a human, a pearl seed, and the act that brings them all together to implant the nucleus of what will later become the pearl itself.

Saltwater vs Freshwater Pearls: A Tale Of Two Pretties

In terms of their origins, there are two types of pearls competing for our attention: saltwater vs freshwater pearls. On the one hand, the most common types of cultured freshwater pearls are grown in rivers, lakes, and ponds and are generally less expensive than saltwater pearls. They grow primarily within freshwater pearl mussels as their host parent.

Since freshwater pearls are grown in waters that are relatively still, they are more manageable for the pearl harvester.

Cultured saltwater pearls, on the other hand, originate in the seas, such as the south sea waters, estuaries, and other bodies of saltwater. They also tend to be more expensive due to their fewer numbers and the labor-intensive process of cultivating them.

The South Sea Pearl, more commonly referred to as the Tahitian pearl, is a product of saltwater oysters living in the warm waters of the South Pacific. Also, since saltwater pearls are grown in waters that are agitated by waves and weather, they have a higher chance of becoming damaged or even lost during harvest, as the waves and currents can cause them to become damaged in nets or other debris.

The Amazing Story of The Tahitian Pearl

How Are Pearls Cultured?

Have you ever wondered exactly how cultured pearls, like Tahitian pearls, are created? This process is quite fascinating! Pearl production involves carefully inserting a tiny seed pearl, crafted from a mollusk shell into the internal structure (often referred to as a pearl sack) of an adult Pinctada Margaritifera oyster. The technician, known as a gaffer, has to take extra-special care not to harm the oyster during their delicate work.

Cultured South Pacific Pearls: The Growing Years

Just as important, and to ensure that the process concludes with a pearl of superior color and shape, they scrupulously sand and shape the nucleus so that it is smooth and uniform in order to encourage a round and natural pearl as much as possible.

This is a labor-intensive process that requires adding a piece of mantle tissue grown from another donor oyster to reduce the possibility of the recipient mollusk’s rejection. This task begins the next phase of the pearl’s creation — which can take two years or more before the contributing oyster’s product reaches maturity and yields the glorious dark body color of its amazing gemstone.

And there is one other important factor. This one also involves time; it is essential that the oyster is not taken away from its watery home for too long because a mollusk requires water to breathe. Because of this, the oyster is quickly replaced for its long waiting period back into its South Sea home.

What Makes A Pearl Unique?

Pearls are a unique gemstone, often seen as a symbol of beauty and elegance. But what makes them so special? What is true of its freshwater relative, the saltwater mollusk is the benefactor of some amazing — and very natural magic.

It takes place inside the oyster’s body during the layering of the nacreous substance. The pearl increases in size because of the secreted coating over the pearl’s nucleus. The process can take years to reach full size.

This is what makes our lustrous pearls so unique and valuable; they are a product of nature, crafted over time and perfected through the mollusk’s delicate process. As a result, each pearl is a special product of nature’s organic engineering, and truly a one-of-a-kind gemstone.

The beauty of each pearl lies in its individual character, from shape and size to color and luster. To add to its uniqueness, each pearl has its own story from the creature that created it, making them an exciting and special addition to any jewelry collection, unlike any other gemstone.

How Does A Cultured Freshwater Pearl Compare To A Tahitian Pearl?

One of the most sought-after types of cultured pearls is the Tahitian pearl, also known as a black pearl. These beautiful gems are produced by the Pinctada Margaritifera, the black-lip pearl oyster found in the warm waters around French Polynesia.

Growing as large as 12 inches (305 mm) in diameter, these mollusks are credited with growing the largest pearls in the world. For that reason, these pearls, often referred to as black pearls, are often larger than their non-Tahitian counterparts. The most expensive pearls can grow up to well over an inch in diameter (25.4 mm) — and fetch thousands of dollars.

While traditional cultured white pearls come in a variety of shapes and sizes, Tahitian black pearls are highly distinctive due to their dark body color and iridescent sheen. These unique gems range from light to dark grey with hints of blue, green, purple, or shimmering aubergine.

In comparison to other pearls, a Tahitian pearl has a higher luster and greater durability because of the thickness of its nacre layers.

Cultured pearls from freshwater habitats have much softer hues than Tahitian cultured pearls. While freshwater pearls may not have the same dramatic natural colors and exotic tones as their saltwater counterparts, they offer an array of delicate whites and pastel shades.

But, ultimately, when comparing each pearl type, it comes down to preference. Whether a lover of the gemstone prefers the exotic appeal of Tahitian black pearls or the subtle beauty of freshwater pearls, both varieties will add a special touch to any piece of jewelry.

Why Are Tahitian Pearls So Popular?

The signature luster of the Tahitian pearl makes them some of the most prized gemstones in the world, beloved for their striking and unique hues, a trait owed to the Pinctada Margaritifera black-lipped oysters that thrive within lagoons throughout French Polynesia.

Ironically, it’s almost impossible to find a truly black specimen — a distinction that makes them so highly valued by gemstone and Tahitian pearl jewelry lovers. Despite the difference between black and non-black shades, they are unmistakably beautiful with dazzling coloration that sets them apart from freshwater pearls — whether the shimmering greyish-toned, smoky charcoal, the somewhat mysterious silver hues, or even other exquisite variations including the exotic greenish variety!
