Akoya pearls are a well-known type of cultured pearl recognized for their bright luster and classic round shape. They are primarily produced by oysters belonging to the species Pinctada fucata martensii. These pearls are traditionally cultivated in coastal waters in countries such as Japan, China, and Vietnam.
The development of cultured pearls began in the early 20th century when pearl cultivation techniques were refined to create consistent, high-quality pearls. Akoya pearls became widely recognized for their elegant appearance and uniformity, making them popular in fine jewelry designs.
Pearl formation occurs when an irritant or bead nucleus is placed inside an oyster. Over time, the oyster secretes layers of nacre around the nucleus, forming the pearl’s surface and contributing to its shine and durability.

Key Characteristics and Grading Factors
Pearl grading helps evaluate quality and appearance using several factors.
Grading Factors Overview
| Grading Factor | Description |
|---|---|
| Luster | Brightness and reflectivity of the surface |
| Surface Quality | Presence of spots or blemishes |
| Shape | Round, oval, or baroque |
| Color | Body color and overtone hues |
| Size | Diameter measured in millimeters |
Akoya pearls typically range from 2 mm to 10 mm, with 6 mm to 8 mm being most common in jewelry.
Influence of Grading Factors
| Factor | Influence Level |
|---|---|
| Luster | Very High |
| Surface Quality | High |
| Shape | High |
| Color | Moderate |
| Size | Moderate |
Luster is often considered the most important factor because it determines how much light reflects from the pearl’s surface.
