The seven pearl value factors are:

Luster

Size

Shape

Color

Surface

Nacre

Matching

Value Factor 1: Luster

Luster is the most important of all the value factors to the beauty of a pearl.

Luster is more than just a surface sheen . It’s caused by light traveling down through translucent layers of nacre , and reflecting back to the eye from deep within the pearl. The effect is that of an inner glow from the heart of the gem .

There are four categories of luster:

Excellent ( Very good )- Reflections are bright, sharp , and distinct

Good – Reflections are bright but not sharp, and they are slightly hazy around the edges

Fair - Reflections are weak, hazy , and blurred

Poor - Reflections are dim and diffused

Value Factor 2: Size

Pearls can be smaller than 2 millimeter in the case of tiny seed pearls, or as large as twenty millimeters for a big south sea pearl. The larger the pearl, other factors being equal, the more valuable it will be. The average sized Akoya pearl sold today is between 7and 7.5 millimeters. In South sea pearls an 8mm pearl is small , 12-15 mm is average , and over 16mm is very large.

As with other gems , a larger pearl is typically more valuable . The larger the pearl , the more rare it tends to be , and the more it costs. But fine quality pearls can be small , and low quality pearls can be large, so a pearl’s ultimate worth depends on how it combines the complete mix of value factors.

Value Factor 3: Shape

Pearls come in many shapes. Depending on how they are formed within the mollusk. Because most people expect pearls to be round, and round pearls are very rare, they tend to be much more expensive than other shapes. Shape in pearls : Round , Near-Round , Oval , Drop, Button, Baroque, Semi-Baroque ,

Standard pearl shapes :

Round – Appears round to the eye

Near-round – Appears almost around to the eye. Some might be slightly out –of-round, elongated, or flattened .

Oval- Symmetrical , rounded oblong shape

Drop-symmetrical , rounded pearl shape. Can be a long or short drop.

Button- Symmetrical , flattened or slightly flattened circular shape. Can be a high-domed or low –domed button.

Baroque – Non – symmetrical shape with a noticeably irregular appearance .

Semi-baroque – Non-symmetrical , off-round, slightly irregular oval, button, or drop.

Value Factor 4: Color

A pearl’s color , as well as the color of any other object on earth.

Color is an important factor to consider for several reasons. Individuals have very personal preferences in terms of color based on their own skin, eye, and hair color and should select a color that is best suit to them. Color also affects cost because some are rarer than others. Cultured pearls come in a variety of colors from pink to black. While the color of a pearl is really a matter of the wearer's preference , usually rose or silver/white pearls tend to look best on fair skins while cream and gold toned pearls are flattering to darker complexions. In naturally "black" cultured pearls, the color range from light gray to dark gray, and also includes blue and green; in black pearls, a green overtone is the rarest and most costly, especially when it results in an intense "peacock" color. Cultured pearls are available in many natural colors - white, black, gold, pink, green, blue, gray ! from many parts of the world.

Pearl color can have main characteristics:

Body color- the dominant , overall color of a pearl

Overtone – One or more translucent color that appear over a pearl’s body color

Orient- Iridescent , rainbow color shimmering on or just below a pearl’s surface.

Value Factor 5: Surface

In an idea world , all pearls would be spotless. In reality , a completely clean pearl is a rare treasure . Since rarity influences value, the prices of such pearls run extremely high . Most consumers must settle for some degree of surface irregularity in the pearls they purchase . Cleanliness refers to the absence of disfiguring spots, bumps or cracks on the surface of a pearl. The cleaner the surface of the pearl, the more valuable. This refers to the pearl's freedom from such surface blemishes as small blisters, pimples, spots, or cracks. Imperfections may also appear as desk spots, small indentations welts or blisters, or surface bumps. Think of the pearl's surface as you would your own skin. Just as our own is rarely completely free of little imperfections, so it is with the pearl.

Very Clean- pearls can be blemish-free or contain minute surface characteristics that are very difficult to see when examined by a trained observer

Clean (lightly blemished) – pearls show minor surface irregularities when inspected by a trained observer

Moderately Blemished – pearls show noticeable surface characteristics

Heavily Blemished – pearls show obvious surface irregularities.

Value Factor 6: Nacre

Nacre is the very essence of the pearl itself. Its close relationship to luster makes nacre quality a crucial value factor. A pearl’s appearance helps determine its quality , and it has a lot to do with whether the nacre is thick or thin . Of course , thicker nacre doesn’t guarantee an attractive , lustrous appearance . But most of the time , pearls with thicker nacre tend to be more lustrous as well .

Nacre that’s too thin has a negative effect on a pearl’s value. Pearls that look chalky or dull , or pearls that have a visible nucleus , are unattractive. They lack the gleam that is the hallmark of this cherished aquatic gem .

Value Factor 7: Matching

No two pearls are exactly alike . Realistically , then, individual pearls in a piece of jewelry can’t be completely identical. they might actually be quite different. It takes an enormous amount of skill and labor to sort harvested pearl.
