What Is Pearl?

Pearls are lustrous and beautiful gemstones with unique and beautiful colors. They are commonly used in jewelry, decorative objects, and high-quality fabrics. They are also used in cosmetics, food products, and pharmaceuticals for their powerful antioxidants and other medicinal properties.

It is an organic gemstone that forms from the inside of certain species of oysters and other marine animals. It consists of layers of concentric growth rings like those of a tree. These layers are composed of several types of minerals. The color is due to the presence of these minerals in different concentrations, which give each layer a unique hue. The mineralogical composition can be different between species or individual oysters. As such, it isn’t easy to standardize the quality of pearls, though there are some recognized grades (for example, AAA+ or AA+).


The etymology of the word “pearl” is interesting, as it reveals the rich history of this precious gemstone. It comes from the Anglo-Saxon “pæril,” which means “to pour.” In ancient times, pearls were often used as a currency and believed to have medicinal properties. They were even said to be able to cure ailments like gout and rheumatism.

How is Pearl Formed?

Pearls are formed when a mollusk, like an oyster, clam, or mussel, produces a layer of nacre to cover an irritant inside its shell. The irritant is typically a parasite, foreign material, or some form of calcium carbonate, such as sand. As more and more layers of nacre are deposited, the foreign object becomes coated in a smooth and lustrous form. The result is an organic gem composed of mother-of-pearl layers of calcite and aragonite crystals.

Depending on the species and environment in which it lives, the length of time it takes to form will vary. Generally, though, it take at least two to three years to harvest. Natural pearls are the rarest and most valuable kind. They form spontaneously in their natural surroundings, but only occasionally.

Freshwater and Saltwater pearls are cultivated in farms and make up most of those sold today. Imitation pearls can also be found in inexpensive jewelry.

Pearl Appearance

Luster is determined by the number and thickness of its layers. Iridescence—the play of colors we see is caused by light bouncing off overlapping layers.

The most common type of pearl is baroque, which has a spherical shape. Other shapes include drop and teardrop. The gemstones can also be classified by their color: white, cream, gold, or silver. The most valuable are black and Tahitian pearls. In addition, these gems can be dyed yellow, green, blue, brown, pink, purple, or black.

How To Tell If A Pearl Is Real?

The best way to tell if a pearl gemstone is real is to have it tested by a professional jeweler. You can also use some of these tests at home:

  • Acetone test:  Put a few drops of acetone on it, and it should turn cloudy. If it’s real, this won’t happen. The surface of the sampleshould also be smooth.
  • Check for Inclusions: The gemstone surfaces are smooth and lustrous. Check for cracks on the surface of your stone. There are several ways to repair small cracks, but large ones can often damage the gem beyond repair—and may drastically reduce the value of your stone. Although small cracks in a pearl may not cause it to lose much of its value, you should avoid purchasing any pearls with visible imperfections.
  • Color Consistency: The gem should have a consistent color. If you can see a difference between the center and edge of your pearl, it’s likely to be fake. A fine-quality pearl will be consistent in color. Looking closely at a pearl and seeing its various shades could indicate that the stone has been dyed or bleached. A natural pearl’s surface should also be shiny and lustrous.

When buying, ensure your seller has a good reputation and will give you your money back if the stone differs from what was advertised.

Natural vs. Cultured Pearls

Pearls can be divided into two main categories: natural and cultured. Natural pearls are formed inside the shells of mollusks completely by chance, without any human intervention. Therefore, they are extremely rare and valuable, as their formation is rare. In contrast, cultured pearls are made by intentionally introducing a small irritant into the mollusk, which triggers the formation process.

Cultured pearls are further classified into different types based on the type of mollusk used and the cultivation method. Freshwater is grown in Freshwater mollusks and can be found in various shapes and colors. A specific kind of saltwater mollusk produces Akoya pearls. They are known for their perfectly round shape and high luster. South Sea pearls are the largest and rarest type grown in the warm waters of the South Pacific.

While natural ones are highly coveted due to their rarity and uniqueness, the vast majority available in the market today are cultured. It is because naturals are extremely rare and difficult to find, and the process of producing cultured has been refined and perfected over the years. Despite this, natural pearls still hold a special place in the world of gemstones.

Four Major Types of Cultured Pearls

The four major cultured pearls are Akoya, Freshwater, Tahitian, and South Sea.

  1. Akoya pearls are traditionally known for their high luster, perfectly round shape, and white-to-cream body color. They are produced in Japan and China and are typically smaller than other cultured types, ranging from 2 mm to 11 mm. These are often used in classic and elegant jewelry, such as necklaces and earrings.
  2. Freshwater pearls are grown in Freshwater mollusks and are produced mainly in China. They come in various colors, including white, pink, lavender, and peach, and are usually baroque or oval. Freshwater are generally more affordable than other cultured ones and are commonly used in fashionable jewelry pieces.
  3. Tahitian pearls are grown in black-lipped oysters in French Polynesia and are known for their unique dark body colors, which range from dark green to gray to black. They are also larger than Akoya, typically round or semi-round in shape. Tahitian are considered some of the most exotic and valuable in the world and are often used in high-end jewelry pieces.
  4. South Sea pearls are the largest and rarest type produced in the warm waters of Australia, Indonesia, and the Philippines. They come in various colors, including white, gold, and champagne, and are typically round or baroque in shape. South Sea  are highly valued for their rarity, size, and luster and are often used in luxurious and elegant jewelry pieces.

Pearl Value and Quality Factors

Pearls value is determined by seven factors: size, shape, color, luster, surface quality, nacre quality, and matching. The last factor is especially important for jewelry sets with two or more pieces.  


The size can greatly impact its value, with larger pieces generally being more valuable than smaller ones. The size is measured in millimeters and can range from as small as 1 mm to as large as 20 mm or more.


Pearls come in various shapes, with round being the most highly valued due to their rarity and symmetry. However, other shapes, such as oval, drop, or baroque, are popular and can create unique and interesting jewelry designs.


They come in many colors: white, cream, pink, silver, and black. However, the most valuable and highly prized colors are typically natural and rare.


The luster is the brightness and reflectivity of its surface. Therefore, high-quality should have a bright, mirror-like shine that reflects light evenly across the surface.

Surface quality

The surface should be free of blemishes, cracks, and other imperfections. The fewer blemishes a piece has, the higher its quality and value.

Nacre quality

The thickness and quality of the nacre layer can greatly impact its durability and longevity. Gemstones with a thick, high-quality nacre layer are more valuable and durable than those with thin or poor-quality nacre.


When purchasing a set, it’s important to ensure they are well-matched in size, shape, color, luster, and surface quality. A set that are perfectly matched will be more valuable and visually appealing than a set with noticeable variations between the pieces.
