Do Pearls Get More Expensive with Age?


Pearls have long been celebrated for their timeless elegance and natural beauty. As one of the oldest known gemstones, pearls have adorned royalty and fashion icons alike, symbolizing purity, wealth, and sophistication. However, a common question that often arises among enthusiasts and collectors is: “Do pearls get more expensive with age?” This article delves into the intricacies of pearl valuation over time, examining the factors that influence their prices and how pearls age. By understanding these elements, you can gain valuable insights into the worth of pearls, whether you’re looking to buy, sell, or simply appreciate these oceanic treasures.

What Are Pearls?

Definition and Formation of Pearls

Pearls are unique among gemstones because they are organic, created by living organisms. They form inside the shells of certain mollusks, such as oysters and mussels, through a fascinating natural process. When an irritant, such as a grain of sand or a parasite, enters the mollusk, it secretes layers of nacre around the intruder to protect itself. Over time, these layers accumulate and harden, eventually forming a pearl. The nacre, also known as mother-of-pearl, consists of microscopic crystals of calcium carbonate aligned in such a way that they reflect light, giving pearls their characteristic luster.

Types of Pearls: Natural vs. Cultured

Pearls can be broadly categorized into two types: natural and cultured. Natural pearls are extremely rare and form without any human intervention. They are typically found in the wild and are valued for their uniqueness and organic origins. Due to their scarcity, natural pearls command high prices in the market.

Cultured pearls, on the other hand, are cultivated with human assistance. In this process, a small bead or piece of tissue is intentionally inserted into the mollusk to stimulate nacre production. Cultured pearls make up the majority of pearls available today and come in various types, each with distinct characteristics:

  • Akoya Pearls: Known for their high luster and round shape, Akoya pearls are typically white or cream-colored and are cultured primarily in Japan and China.
  • Tahitian Pearls: These pearls, cultured in the warm waters of French Polynesia, are renowned for their dark colors, ranging from black to green, blue, and purple.
  • South Sea Pearls: Cultured in the waters of Australia, Indonesia, and the Philippines, South Sea pearls are the largest and often the most valuable, known for their satin luster and shades of white, silver, and gold.
  • Freshwater Pearls: These pearls are cultured in freshwater lakes and rivers, mainly in China. They come in a variety of shapes and colors, offering a more affordable option compared to their saltwater counterparts.

Understanding the differences between natural and cultured pearls is essential for appreciating their value and knowing what to look for when purchasing pearls.

Factors That Affect Pearl Prices


Luster is one of the most critical factors in determining a pearl’s value. It refers to the quality and intensity of light reflecting off the surface of the pearl. High-quality pearls exhibit a sharp, bright reflection, making them appear radiant and almost glowing. The luster is influenced by the thickness and arrangement of the nacre layers; the thicker and more uniform the layers, the better the luster. Pearls with excellent luster are highly sought after and command higher prices, as they possess a captivating brilliance that enhances their visual appeal.


The size of a pearl significantly impacts its price. Generally, larger pearls are more valuable due to their rarity and the longer cultivation period required to produce them. The size of a pearl is measured in millimeters, with even a slight increase in diameter resulting in a substantial price difference. For example, while a 6mm pearl might be relatively affordable, a 12mm pearl of the same quality can be exponentially more expensive. This principle applies across all types of pearls, making size a crucial determinant of value.


Pearls come in various shapes, including round, near-round, oval, button, drop, and baroque. Among these, perfectly round pearls are the most prized and valuable due to their symmetry and the precision required to cultivate them. Near-round pearls, while slightly less valuable, are still highly desirable. Other shapes, like baroque (irregularly shaped) pearls, offer unique and artistic appeal but typically fetch lower prices compared to their round counterparts. The shape of a pearl can influence its use in jewelry, with round pearls often reserved for classic designs and baroque pearls used for more avant-garde pieces.


Color plays a vital role in pearl valuation, with certain colors being more desirable than others. The most common pearl colors are white and cream, but pearls can also be found in shades of black, grey, silver, gold, pink, blue, green, and lavender. The color preference varies by culture and market demand; for instance, white and pink pearls are highly favored in Western markets, while golden pearls are particularly prized in Asia. The depth and uniformity of color, along with the presence of overtones (secondary hues that enhance the primary color), contribute to a pearl’s overall value.

Surface Quality

The surface quality of a pearl refers to the presence or absence of blemishes, such as spots, pits, or wrinkles. Pearls with clean, smooth surfaces are more valuable, as imperfections can detract from their beauty and durability. While minor blemishes are common and often acceptable, especially in larger pearls, extensive surface flaws can significantly lower a pearl’s price. Evaluating surface quality involves a careful inspection to ensure that the pearl’s imperfections are minimal and do not affect its overall appearance.

Nacre Thickness

Nacre thickness is a crucial factor affecting a pearl’s durability and beauty. Thicker nacre layers contribute to a richer luster and greater longevity, making the pearl more resistant to chipping and wear. Cultured pearls with thin nacre layers may exhibit a duller appearance and are more prone to damage over time. When assessing nacre thickness, buyers should look for pearls with deep, layered nacre, as these are typically more valuable and will maintain their luster and integrity for many years.

By understanding these key factors that influence pearl prices, buyers and enthusiasts can make informed decisions when selecting pearls and appreciating their true value.

How Do Pearls Age?

Physical and Chemical Changes Over Time

Like all organic materials, pearls undergo physical and chemical changes as they age. Over time, the nacre that constitutes a pearl can degrade due to various environmental factors. Exposure to heat, humidity, acids, and even body oils can affect the luster and surface quality of pearls. Pearls are composed primarily of calcium carbonate, which is susceptible to degradation. This process can lead to a gradual loss of luster and the development of a chalky appearance. Proper care and storage are crucial to mitigate these effects and preserve a pearl’s beauty and value over time.

Impact of Environmental Factors on Pearls

Environmental factors play a significant role in the aging process of pearls. Humidity, temperature fluctuations, and exposure to pollutants can all accelerate the degradation of nacre. High humidity can cause the layers of nacre to swell and separate, while extreme dryness can make them brittle. Direct sunlight and heat can also cause pearls to fade or discolor. Additionally, contact with acidic substances, such as perfumes, cosmetics, and even sweat, can erode the nacre layers, leading to surface damage. To preserve their quality, pearls should be stored in a stable, controlled environment, ideally in a soft cloth or pouch to protect them from scratches and environmental harm.

Do Pearls Improve with Age?

Myths and Facts About Aging Pearls

There is a common myth that pearls improve with age, gaining value and beauty as they grow older. While it is true that some pearls can become more desirable over time, this is not a universal rule. The aging process can enhance the character of certain pearls, especially those that develop a patina or unique coloration. However, many pearls may deteriorate if not properly cared for, losing their luster and structural integrity. The idea that all pearls improve with age is largely a romanticized notion; the reality depends on the type of pearl, its quality, and the conditions in which it has been kept.

How Aging Affects Luster and Surface Quality

As pearls age, their luster and surface quality can either improve or degrade, depending on how they are maintained. Well-cared-for pearls can retain their luster and even develop a deeper, more nuanced sheen known as patina, which can enhance their value and appeal. On the other hand, neglected pearls may suffer from surface deterioration, leading to a loss of luster and the appearance of blemishes. The aging process emphasizes the importance of proper pearl care, as the preservation of their initial beauty significantly influences their long-term value.

Do Pearls Get More Expensive with Age?

Historical Perspective on Pearl Pricing Over Time

Historically, pearls have been highly valued, often fetching prices that rival those of precious gemstones like diamonds and rubies. In the past, natural pearls were the epitome of luxury and exclusivity, primarily due to their rarity and the labor-intensive process of harvesting them from the wild. This scarcity meant that older, high-quality natural pearls often appreciated in value as they became more difficult to find. However, the advent of cultured pearls in the early 20th century significantly changed the landscape of the pearl market. Cultured pearls, while still valuable, are more abundant and accessible, which influences their pricing dynamics over time.

Comparison of Old vs. New Pearls in the Market

When comparing old pearls to new ones, several factors come into play. Antique or vintage pearls, especially those with historical significance or exceptional quality, can command high prices. Their value is often enhanced by their provenance, unique characteristics, and the craftsmanship of the jewelry in which they are set. New pearls, particularly those of high quality and exceptional luster, can also be highly valuable, but they typically do not carry the same historical or sentimental weight as antique pearls. The market value of both old and new pearls depends on their condition, type, and desirability among collectors and buyers.

Factors That May Lead to an Increase in Value for Older Pearls

Several factors can lead to an increase in the value of older pearls. Provenance, or the documented history of a pearl, can significantly enhance its worth, especially if it has been owned by notable individuals or is part of famous collections. The rarity and uniqueness of older pearls, particularly natural pearls, also contribute to their value. As natural pearls become increasingly scarce, their prices tend to rise. Additionally, the quality and condition of older pearls play a crucial role; well-maintained pearls that have retained their luster and surface quality are more likely to appreciate in value over time.

The Appeal of Antique Pearls

Why Collectors Seek Antique Pearls

Antique pearls hold a special allure for collectors due to their historical significance, unique characteristics, and the craftsmanship of the eras in which they were created. Collectors often seek antique pearls for their rarity and the stories they carry. Each antique pearl piece can offer a glimpse into the past, showcasing the styles and preferences of previous generations. Moreover, antique pearls are often part of heirloom jewelry, passed down through families, which adds sentimental value and a sense of continuity and tradition. The combination of historical intrigue and tangible beauty makes antique pearls highly desirable.

Examples of Famous Antique Pearls and Their Values

Several famous antique pearls have made headlines for their exceptional value and storied pasts. For example, the La Peregrina pearl, once owned by Queen Mary I of England and later by actress Elizabeth Taylor, is renowned for its perfect pear shape and historical significance, fetching millions at auction. Another notable example is the Hope Pearl, a 450-carat natural pearl with a rich history dating back to the 19th century. These pearls are celebrated not only for their beauty but also for their provenance, contributing to their extraordinary market values.

Provenance and Its Impact on Pearl Value

Definition of Provenance in the Context of Pearls

Provenance refers to the documented history of a pearl, detailing its origin, ownership, and any significant events associated with it. In the context of pearls, provenance can include records of where and when the pearl was harvested, previous owners, and its journey through various collections or auctions. Provenance adds a layer of authenticity and historical significance to a pearl, often enhancing its desirability and value. Collectors and buyers place great importance on provenance as it provides assurance of the pearl’s authenticity and can significantly impact its market price.

How a Pearl’s History Can Affect Its Price

A pearl’s history, as documented through its provenance, can greatly influence its price. Pearls with well-documented and illustrious histories, especially those associated with royalty or famous personalities, are often more valuable. The story behind a pearl adds to its mystique and appeal, making it more attractive to collectors and enthusiasts. Additionally, provenance can provide insights into the quality and authenticity of a pearl, offering buyers confidence in their investment. As a result, pearls with rich and verified histories tend to command higher prices in the market.
