Thanks to the aggressive advertising campaigns sponsored by the diamond industry, anyone who buys diamonds can confidently enter into a transaction armed with enough information to ask the right questions. At the pre-purchase stage, you will ask the sellers about five Cs: carrots, cut, clarity, color and cost. As long as you trust the jeweler, you can be assured of the value of the gems you are interested in based on their answers. But what about pearls? What questions do you ask? What does a high quality pearl look like? What are the traits to avoid? Here we tell you what a pearl is worth. We give you questions to ask your jewelry and tools to judge this brilliant gem yourself.

Pearl value factors

There is no international standard for grading pearls, and there is a widely used method for evaluating these beautiful colored gemstones. Developed by the Gem Science Institute (GIA), the world’s largest non – profit gem research institute, this classification system considers seven characteristics of pearls in determining value. They are: size, shape, color, gloss, surface quality, pearl quality and composition. Let’s take a look at each of them in relation to beautiful cultural pearls.

Pearl size

The head of a pearl can be as small or as big as a golf ball, but in reality, somewhere between these two extremes is the norm.Size is determined by many factors. This includes the size of the gem-producing animal, the size of the beads deposited, the time the oyster or mollusk was allowed to make pearls, the climate and environmental conditions, and the health of the pearl-producing animal. .Different types of pearls have different size ranges. For example, because they are produced in relatively small oysters, the cultural aqua pearls are much smaller than their southern seagull counterparts, making them one of the largest mollusks in the world. Cultivated in Maxima. This large creature can accept a large number of beads and can deposit Knocker faster than its smaller cousin, which combines with the organic matter that makes up a pearl. Be sure to find out what kind of pearls you are looking for (freshwater, aqua, South Sea or Tahiti). They all have different desired size ranges, and anything outside the range reflects the price. Guide: Acoas usually grow to 2 to 11 mm. 8-14 mm. Tahitian; South Sea pearls 9 to 20 and freshwater pearls 4 to 11 mm.

A large pearl will cost more when everything else is the same. Larger pearls take longer to grow and are not as common as smaller ones. However, like everything else, beauty is in front of the viewer’s eyes. For some people, brilliance, which is another factor in pearl value, may be more important than size.When estimating size, keep in mind that there are small, high quality pearls as well as large, poor quality pearls. Therefore, one of the factors to consider when judging the quality of pearls is the size of the pearl. It brings us …


Close your eyes and think of a pearl necklace. Do you see A necklace of white round gems, right? The round white pearl necklace is a staple of seasonal jewelry and is a traditional classic in many cultures. As you might expect, round pearls are ideal because of the demand, but they are also worth it because they are rare. .

Although pearl cultivation methods are always advanced, perfect round pearls are rare. (Acoya cultures usually contain more spherical pearls than other pearls.) According to the GIA, matching pearls can take years to gather enough high-quality round cultural pearls. Round or nearly round pearls cost more than other shapes. That doesn’t mean other ways aren’t worth it. (Remember the saying, “Beauty is in the eye of the beholder”). According to the GIA, the shapes of the droplets can sometimes be equal to the value of the circles, especially when they are symmetrical and well formed.Aren’t you a conservative? Pearls come in many shapes and, depending on what you like, they may be more attractive but less expensive than round ones. The pearl shape includes button, oval, dot, semi-baroque and baroque. Some pearl bars look like crosses and coins. Some of them are called round pearls, with holes around the circumference of the gemstone. These beauties can make wonderful jewelry.

The GIA classifies pearls into three main shapes:

1. Spherical: Round or almost round pearls
2. Symmetrical: These pearls have equal parts when divided into two
3. Baroque: pearls without clear symmetry

Although the shapes of pearls vary, those that show some kind of symmetry usually cost more. But Baroque pearls can be very beautiful and unusual, even if they are grouped into a single shape or similar shape in a necklace or bracelet. Baroque pearls often look oriental, adding to the value of pearls with a pleasing glittering rainbow effect. Many designers prefer to work with Baroque pearls for their endless design capabilities and many consumers buy them for their unique beauty.


Although white can always win the pearl color competition, pearls come in a variety of colors. The pearls mentioned above can range from white to gray-black to lavender, pink, orange and many more shades. The choice is yours, but when choosing, keep in mind the skin tone of the wearer – the color of the pearl should complement the wearer’s complexion.When describing the color of pearls, jewelers speak of three characteristics: the tone, which is the normal color of pearls, is seen in the first impression; Overton is described as a secondary rain color that is not always present but when you look at the pearl (i.e. pink on white pearls) and oriental is not always present but may be better as mentioned above.The popularity of pearl colors increases and decreases; Value is determined by what is in fashion. As you might expect, white is always “in style”. Lavender pearls are also very popular now. Tahitian cultural pearls, usually dark gray, dark green, or dark blue / purple, were not surprising before the 1970s, but are now widely sought after and very expensive. Sometimes, a model or celebrity wears a pearl color and that color will see an increase in popularity.

Similar in size, pearls show similar characteristics in color. Acoas, for example, are usually white or cream in color. Tahitians are usually black, gray or brown; The South Seas are usually silver, white, or a beautiful golden hue, while freshwater comes in white, cream, and a wide range of pastels. According to the GIA, if the color of the pearl is rare, fine pearls that show that color have a higher price.


As pearls are known for their inner brilliance, they are distinguishable from other gemstones. According to the GIA, “brilliance is the most important of all the values ​​for the beauty of a pearl.”Based on many factors, including the thickness and growing conditions of the knuckle, the brightness is good as the knuckle shines from the inside when the knuckle is translucent and its plates overlap. Chunky mother pearls do not guarantee a crisp shine, but it certainly helps. The sharper the reflection of the pearl, the better the brightness. The GIA defines four gloss categories:

Excellent – Reflections are bright, sharp and varied

• Good: Reflections are bright but not sharp and slightly blurred around the edges
• Fair – Reflections are weak, blurry and blurry
Or weak: reflections are dark and dilute

Brightness is the easiest pearl value factor to rank. Place a pen-like object near the beads. (Be careful not to paint the gem.) The sharper the reflection, the better the brilliance and pearl. However, keep in mind that each type of pearl has its own characteristic brilliance. Acoas is famous for its delicate, smooth brilliance, while cultural pearls from the South Seas, for example, have a more delicate, soft cover.

Surface quality

Pearls are organic and therefore “imperfect” which means that they are not smooth, shiny, perfectly rounded orbs every time they emerge from oysters. As layered natural objects, they exhibit surface features such as abrasions, bumps, chips, cracks, pits, scratches and wrinkles. Most people do not see a perfect pearl in their lifetime and in fact small irregularities on the surface are not worth the value of a pearl.

As defined by the GIA, pearl surface has four classification characteristics:

Clean: Pearls may be flawless or flawless, or they may have very minor surface features that are difficult to see when examined by a trained observer.
• Slightly spotted – The beads show small surface irregularities when examined by a trained observer
Moderate imperfections: Pearls show prominent surface features
St severely stains: The surface of the pearl shows irregularities, which can impair its durability.

The general appearance of a pearl determines its value. Clear or multi-surface features or large imperfections that affect the durability of a gem are far more valuable than a pearl that looks pure. Most of us can’t get the perfect pearl necklace, but fortunately, small bumps and scars can often be hidden with a drill. According to the GIA, “… Pure pearls are a rare commodity. The price for such pearls is extremely high, as rarity affects value. Many consumers have to settle for a certain unevenness on the surface of the pearl they buy. Even the finest pearls can have minor surface features.

Quality of pearls

The quality / thickness of the mother pearl that is directly related to the shine is a very important factor in the value, fortunately can be judged with the naked eye. It is better to estimate the thickness by X-ray machine or by cutting pearls, but most of us do not have such a machine and we do not want to cut the pearl in half. (Think about it for a minute!)

Take a look at the pearls you want to value. A dark, chalky appearance means that the nose may be thin. In some cases, the nose is so thin that the core of the beam is visible. Do not buy these pearls, they do not exist!

The GIA classifies mother pearls into three types:

Air Fair: The essence of pearls is striking and the gems do not look chalky
Visible essence: The pearl shows evidence of its bead essence through the pearl. When the bead turns through a light source, it displays a strong “flicker” (light and dark light).
Alk Lime Appearance: Pearl matte and opaque

Pearls have a negative effect on the value of pearls, but thicker mother pearls do not guarantee an intense shine. Good pearls can be cracked, peeled or degraded and pearls do not last long. (Unlike other gemstones, pearls do not restore their original beauty by polishing.) Pearls are more durable and more valuable. If you get a chance, ask about the thickness of the nail.

Interesting fact: Most freshwater cultural pearls are grown only from the covering tissue rather than from the pearl, and as a result, the pearl is the pearl. Many pearl experts say that today’s Chinese freshwater cultural pearls are the opposite of the beauty of Japanese akoya.


As you can imagine, this pearl value factor only works when a piece of jewelry contains more than one pearl. Some designers do not deliberately combine pearls for an aesthetic effect, but when the threads are meant to be uniform, it is important to consider how well the gem blends. Fortunately, this is easy to determine. Look at the fibers and see the obvious differences in the gems. (Some jewelers will try to hide small or imperfect pearls near the wrist, so check out this area carefully.)

When evaluating blended yarns, keep in mind that cultural pearls are organic, not even made from a factory mold. The two are not exactly the same, so a perfect match cannot be made. However, as long as the piece is generally uniform, this is not a racket of jewelry. To test, look at the thread, hold it close, extend your arms and look at it. Is the total size of the pearl the same? Colours? Shape? Gloss? Quality of pearls? If they are the same, they are compatible.

The GIA defines three categories of adjustments:

Excellent: The pearls have a uniform appearance and are perforated in the center
• Good: Shows small changes in the uniformity of the section
• Fair: Pearls are different from each other.

According to the GIA, “The collection of collected pearls requires a great deal of skill and work. The time and effort required to produce a type of yarn that fits the pearl well reflects its market price.


Because they are produced in different animals in different environments under unique conditions, each type of pearl has its own desired characteristics. When the characteristics of a pearl deviate from the norm for its type, the pearl becomes more valuable.Every pearl is unique and uniquely beautiful. What are the most beautiful pearls and pearls? it’s up to you. (This author favors Baroque white freshwater pearls and gold pearls in the South Seas).


best wishes! Now you know what to look for when buying pearls and what questions to ask. Remember that the value of a pearl depends on its overall appearance. Remember that not all value factors are important to everyone. For example, you may be more interested in the color of the pearl than the size of the pearl. Like everything else, personal tastes dominate. Go now and buy with confidence.
