What Determines the Value of a Pearl?

The value of a pearl is determined by a combination of key factors, each contributing to its overall beauty and rarity. While preferences can vary, these seven attributes are universally recognized in pearl grading and valuation:

1. Luster

The most critical factor in determining a pearl’s value. Luster refers to the quality and intensity of light reflecting off the surface and from within the layers of nacre. The sharper and more mirror-like the reflection, the more valuable the pearl.

2. Size

Measured in millimeters, pearl size plays a significant role in valuation. When all other factors are equal, larger pearls are rarer and more valuable.

3. Shape

While pearls come in a variety of shapes, round pearls are the most prized due to their symmetry and rarity. However, high-quality baroque and other unique shapes can also be highly desirable.

4. Color

The depth, consistency, and overtone of a pearl’s color affect its value. Some colors are naturally more sought-after due to rarity and demand, such as deep golden South Sea pearls or naturally vivid Tahitian pearls.

5. Surface Quality

A pearl’s surface should be as smooth and blemish-free as possible. Fewer marks, pits, or dull spots enhance its beauty and value. However, minor imperfections are natural and expected in most pearls.

6. Matching

When pearls are used in strands or jewelry sets, consistency in size, shape, color, and luster significantly impacts their value. Well-matched pearls create a harmonious, luxurious appearance.

7. Nacre Thickness

This factor applies primarily to bead-nucleated pearls (such as Akoya, South Sea, and Tahitian pearls). The thicker and more uniform the nacre, the more durable and valuable the pearl. Pearls with overly thin nacre may appear chalky or lack luster. For non-beaded pearls, such as traditional freshwater pearls and keshi pearls, nacre thickness is not a concern, as they are composed entirely of solid nacre.

Each of these factors plays a role in determining a pearl’s worth, and their importance can vary depending on the type of pearl. If you have any questions or need guidance in selecting the perfect pearl, our support team is always happy to help!
