Judge the quality of pearl

There are four aspects can affect pearl's quality, they are size, shape, color and skin light.

if the pearl sizes are different, their worth are very different, too. The larger the pearl, the more valuable.

Pearl's shape has precisely round, ordinary round, flat, bread-shaped, oval, milk fall-shaped, gourd-shaped, etc. The precisely round is the best, followed by the other form, irregular shape is the bads.

Pearl colors are white, yellow, pink, purple, black, gray and so on.

Pearls' quality is quite different, according to international standards, pearls are divided into five levels, The high-quality pearl which diameter is more than 9 mm can ask price each, each price is very high, even can up to million of dollars.

And substandard Pearl (raw beads, dirt beads, with light bead) ask price in tonnes or tens of dollars / kg, which is generally only as medicine.

Pearl is also divided into natural pearls and cultured pearls, and natural pearl is nearly exhausted as early as the late Ming and early Qing Dynasty of China (about in the middle of 17th-century), in the natural environment, every ten thousand mussels can only be picked about 10g pearls, and small size, irregular shape, plus with the pearl picking is a very dangerous and difficult work, along with the rise of cultured pearls, the pearl-picking industry has long disappeared.

So there is no longer a natural pearl, and now pearls on the market, basically, are all cultured pearls.

Cultured pearls are divided into sea pearls and freshwater pearls.

The advantage of freshwater pearls is that no nuclear, easy maintenance, more production; and the disadvantage is that 80% worse shape which only as medicine, the precisely round pearls is very rare.

The disadvantage of seawater pearls is that nuclear, production is very easy affected by the natural environmental, and the advantage is good color, precisely round, most are able to make jewelry.

Pearl Definition

Almost any shelled mollusk can, by natural processes, produce some kind of "pearl" when an irritating microscopic object becomes trapped within the mollusk's mantle folds, but the great majority of these "pearls" are not valued as gemstones. Nacreous pearls, the best-known and most commercially-significant pearls, are primarily produced by two groups of molluscan bivalves or clams. A nacreous pearl is made from layers of nacre, by the same living process as is used in the secretion of the mother of pearl which lines the shell.

A "natural pearl" or "wild pearl" is one that forms without any human intervention at all, in the wild, and is very rare. Many hundreds of pearl oysters or pearl mussels have to be gathered and opened, and thus killed, in order to find even one wild pearl, and for many centuries that was the only way pearls were obtained. This was the main reason why pearls fetched such extraordinary prices in the past. A cultured pearl is formed in a pearl farm, using human intervention as well as natural processes.


One family of nacreous pearl bivalves – the pearl oyster – lives in the sea, while the other – a very different group of bivalves – lives in freshwater; these are the river mussels such as the freshwater pearl mussel. Saltwater pearls can grow in several species of marine pearl oysters in the family Pteriidae. Freshwater pearls grow within certain (but by no means all) species of freshwater mussels in the order Unionida, the families Unionidae and Margaritiferidae.

Pearl Introduction

A pearl is a round shiny object produced by mollusks and used in jewelry.

More, A pearl being extracted from an pearl oyster, it is a hard object produced within the soft tissue (specifically the mantle) of a living shelled mollusk. Just like the shell of a mollusk, a pearl is made up of calcium carbonate in minute crystalline form, which has been deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes of pearls (baroque pearls) occur. The finest quality natural pearls have been highly valued as gemstones and objects of beauty for many centuries, and because of this, the word pearl has become a metaphor for something very rare, fine, admirable, and valuable.

The most valuable pearls occur spontaneously in the wild, but they are extremely rare. Cultured or farmed pearls from pearl oysters make up the majority of those that are currently sold. Pearls from the sea are valued more highly than freshwater pearls. Imitation or fake pearls are also widely sold in inexpensive jewelry, but the quality of their iridescence is usually very poor, and generally speaking, artificial pearls are easily distinguished from genuine pearls. Pearls have been harvested and cultivated primarily for use in jewelry, but in the past they were also stitched onto lavish clothing. Pearls have also been crushed and used in cosmetics, medicines, and in paint formulations.


Pearls that are considered to be of gemstone quality are almost always nacreous and iridescent, wild or cultured, like the interior of the shell that produces them. However, almost all species of shelled mollusks are capable of producing pearls (formerly referred to as "calcareous concretions" by some sources) of lesser shine or less spherical shape. Although these may also be legitimately referred to as "pearls" by gemological labs and also under U.S. Federal Trade Commission rules,[1] and are formed in the same way, most of them have no value, except as curios.
