The pearl, traditionally associated with the month of June, holds a unique position among gemstones. Unlike gems formed within the earth, the pearl originates within a living organism – the pearl oyster or mollusk. While often envisioned as a pristine white orb, pearls exhibit a surprising range of colors, shapes, and surface characteristics. This article will explore the qualities that define a pearl, focusing on the aspects of color, shape, luster, and surface as outlined in available resources.

Gemological Properties
Pearls are organic gemstones, differing significantly from minerals in their formation and composition. They are formed within the soft tissue of a living mollusk, typically an oyster or a mussel. The process begins when an irritant – a parasite, a grain of sand, or a piece of shell – enters the mollusk. As a defense mechanism, the mollusk coats the irritant with layers of nacre, a substance composed of calcium carbonate in crystalline form. These concentric layers of nacre gradually build up, creating the pearl.
The sources emphasize several key properties to consider when selecting a pearl: surface, luster, color, and shape.
Color
Contrary to popular belief, pearls are not limited to white. The sources indicate that pearls can be found in a spectrum of colors, including black, gray, blue, yellow, cream, lavender, and mauve. This variety in color is influenced by the type of mollusk, the water conditions, and the nacre’s composition.
Luster
Luster refers to the quality of light reflected from the pearl’s surface. It is arguably the most important factor in determining a pearl’s beauty and value. The sources do not provide a detailed description of what constitutes good luster, but imply that it is a desirable characteristic.
Shape
While a perfectly round pearl is considered ideal, the sources note that pearls come in many shapes. This suggests that shape is a matter of preference and does not necessarily diminish a pearl’s value. The variety of pearl shapes adds to their unique appeal.
Surface
The surface quality of a pearl is another important consideration. The sources indicate that a smooth surface is desirable, but do not elaborate on the types of surface imperfections that may occur.
The following table summarizes the key gemological properties discussed in the provided sources:
| Property | Description |
|---|---|
| Color | White, black, gray, blue, yellow, cream, lavender, mauve |
| Luster | Quality of light reflected from the surface (desirable) |
| Shape | Round, and many other shapes |
| Surface | Smooth (desirable) |
