What is a Pearl?

Pearls are produced within the soft tissue of a living shelled mollusk. Just like the shell of a mollusk, a pearl is composed of calcium carbonate in minute crystalline form, which has been deposited in concentric layers. Pearls are often perfectly round and smooth, but many other shapes, known as baroque pearls, can occur.

Pearls have been highly regarded throughout history, and in many cultures, they symbolize purity, elegance and wealth. Pearls can occur naturally or can be cultured by inserting a foreign object, often a small bead or piece of tissue, into a mollusk. The mollusk then secretes layers of aragonite and conchiolin, which make up its shell, resulting in a pearl.

Pearl Value

The value of a pearl can vary significantly based on several factors. Whether the pearl is natural or cultured will impact its overall value most. Natural pearls form without any human intervention and are found in the wild. They are extremely rare and thus very valuable. Cultured pearls are created with human intervention, where a bead or a piece of tissue is inserted into the mollusk to stimulate the pearl-forming process. Cultured pearls are more common than natural pearls and are generally much less expensive.

Other factors that influence a pearls value include: 

  • Size: Larger pearls are rarer and generally more valuable. Pearl size is measured in millimeters.
  • Shape: Perfectly round pearls are the most valuable due to their rarity. However, pearls come in various shapes, such as oval, drop and baroque. Baroque pearls, which are irregularly shaped, are usually less expensive.
  • Color: Pearls come in a range of colors, including white, cream, pink, silver, gold and black. The most valuable and classic pearls are white with a rose overtone. Unusual colors, like black pearls from Tahiti, can also be valuable.
  • Luster: Luster refers to the shine or glow on the surface of the pearl. Pearls with a bright, reflective luster are more valuable than those with a dull or chalky appearance.
  • Surface Quality: Pearls with fewer blemishes, spots or irregularities on their surface are more valuable. Perfectly smooth pearls are rare and highly prized.
  • Origin: Pearls from certain regions, such as the Persian Gulf, are highly valued due to their historical significance and rarity.
  • Type of Mollusk: Different mollusk species produce pearls, and the type of mollusk can influence the pearl’s value. For example, Akoya pearls are produced by the Akoya oyster and are known for their round shape and high luster.
  • Cultivation Period: The longer a pearl is left to develop in the mollusk, the thicker the nacre (layers of calcium carbonate) becomes, resulting in a more valuable pearl.
  • Market Demand: Like everything, trends and market demand also influence the value of pearls. Fashion trends and cultural preferences can affect the desirability and overall value of certain pearls.

It’s important to have pearls appraised by a reputable jeweler or gemologist to determine their exact value, especially for high-value or antique pieces. Certification, provenance and historical significance can also play a role in determining the value of pearls.

    Pearl Care & Cleaning

    Pearls are relatively soft compared to many other gemstones. According to Mohs Hardness Scale, which ranges from 1 to 10 (with ten being the hardest), pearls typically have a hardness of about 2.5. This makes them very susceptible to scratching and damage from harder materials. Because of their relatively low hardness, pearls require careful handling and storage to prevent scratches and other forms of damage. It’s important to keep pearls away from other jewelry or materials that could potentially scratch them. When not worn, pearl jewelry should be stored in a jewelry box lined with soft fabric away from other jewelry pieces.

    When cleaning pearls, it’s crucial to use gentle methods to avoid harming the delicate surface of the pearls. Due to the vulnerability of pearl jewelry, it is recommended to get it professionally inspected and cleaned every few months.
