About the color of pearls

Why pink pearls are considered good

Applying blush to your cheeks will give you a gorgeous look. In this way, pearls also have a pink color , which gives them a gorgeous impression and suits the skin of Japanese people.In the past, they were popular when exported to Europe and America, and around the time of the bubble economy, the stronger the pink, the more popular they were. had.

It seems that toned pearls, which are artificially impregnated with a small amount of red dye, have become commonplace to meet demand.

What is toning?

Many people think that pearls shine with the same color and level as the ones already sold from the time they are extracted from shellfish, but such pearls rarely exist. However, many of the shellfish come out of the shell in a state that has stains and dirt, or the yellow color of the protein between the nacreous layers, and that the value as jewelry cannot be fully demonstrated as it is.

More or less, some kind of treatment has been applied to remove these stains and dirt.

Akoya pearls originally have a faint pink color, but even that pink color may be bleached during the bleaching process.

Toning is a process that compensates for this and returns it to its original state.

This process is simply to compensate for the original pink color, so poor quality pearls will never become beautiful no matter how much color toning you apply. It is also true that color toning reduces color variation and makes it easier to assemble into necklaces.

There are times when color toning is viewed as something wrong in the general public.

This is due to the fact that the pearl industry has avoided making clear statements about color toning for many years in order not to destroy the dreams of customers.

In fact, pink is a color that can be adjusted to some extent through processing.

On the other hand, the color of blue cannot be adjusted through processing unless the pearl itself is deep-fried.

What is atonal color?

This refers to pearls that have not undergone color toning , just a bleaching treatment to remove stains and dirt .

Generally speaking, it cannot be said that it is good because there is no toning, and that it is bad because it is toned.

Pearls that have been toned using appropriate techniques are often more pearl-like, so when choosing pearls, do not be too particular about toning or non-toning.

First of all, it is best to choose a pearl based on whether it is beautiful as a pearl or not.

Six factors that determine the value of pearls

There are six criteria for evaluating the pearl itself. it is

Terry, roll, color, shape, scratches, size

Determine the value by considering each.


It represents the strength of the brilliance, and a pearl that shines strongly is said to have good quality.

When we recommend pearls, this is the most important thing to consider. This is because anyone can see a shining pearl even from a distance and say, ``That pearl is beautiful.''

This shine changes depending on the uniformity of the nacre, the smoothness of the surface, the content of impurities, and the thickness of the roll. A good bead is one that is strong enough to reflect your face.

From a culture perspective, in order to produce the best quality pearls, the shell must be in good condition before the nucleus is inserted, and excellent nucleus insertion techniques are also required. Also, there must be no major damage to the Akoya oyster for 8 to 1.5 months from the time the nucleus is inserted until the pearl is removed. However, management should not be too kind to shellfish.


Roll refers to the thickness of the nacre layer.

Calcium carbonate is secreted within the shellfish's body, and nacre is formed little by little.

Pearls with a thick nacre layer are said to have good curling, and a well-curled pearl will have a deeper color, increase in size, and slow down deterioration over time. The layers of thick mother-of-pearl layer are woven together to create the deep color and texture unique to pearls.

Many appraisal agencies consider that if the thickness of the nacre layer is 0.4mm or more on one side, it meets the criteria for ``Hanadama'' wrapping. When we asked an appraisal agency, we found that many of Yamashita-Pearl's necklaces have wraps of 0.5mm or more.

When it comes to holes of 9mm and 10mm, there is often a winding of 1.0mm or more. That's amazing.

From a culture perspective, the target size for producing pearls is generally determined. Even though it is the same 8mm, the price is different between the 8mm that was made with the aim of 8mm and the 8mm that was rolled up from the 7mm.

color (glow)

Pearls of various colors are produced by the management of shellfish, the sea, and humans. The mother-of-pearl layer is made of the same ingredients as the shiny underside of the shell, so it is not as pure white as the higher-quality ones, but instead emits a variety of colors such as blue, pink, and yellow.

On the other hand, beads with a thin nacre layer look whitish because the core inside is visible.

In addition, even if it is not blue-pink, it is a good bead if you can see multiple colors in one bead.

In addition, one of the main reasons why pearls grown in the sea of ​​Uwajima are so popular is that they have a naturally pink color.


There are two main types: round (perfect circle) and baroque (distortion, drop, oval, daruma, etc.) .

Since it is not an industrial product, strictly speaking, perfectly round beads do not exist.

The closer to a perfect circle, the more expensive it is, but it is also said that a baroque with good curls and a strong texture is more beautiful and more expensive than just a round one.

Shape tends to be judged as a unique characteristic, and baroque pearl accessories made only from irregularly shaped beads are gaining popularity.

From the perspective of aquaculture, whether the seeds are perfectly round or distorted can be determined by a little technique when inserting the seeds.


Refers to the protrusions or dimples on the surface of the pearl.

Pearls grown inside shells have scratches, which are proof that they are genuine pearls and are also unique.

If there is a small scratch, you won't notice it unless you look closely at it even if you are wearing it, so I think it's better to choose by focusing on the texture rather than choosing based on the presence or absence of scratches . However, it is better to have no scratches.

In addition, in order to become thickly wrapped, it is necessary to stay in the sea for a longer time, which increases the chance of scratches appearing.


Akoya pearls range from as small as 3mm to as large as 11mm.

It is written in 0.5mm increments, and if it is written as 7.0mm, it means 7.0 to 7.4mm.

In general, pearls smaller than 6mm are called baby pearls, and even smaller pearls of 3mm to 4mm are called rindama.

If all other evaluation criteria are equal, the larger the item, the more rare it is and therefore the higher the price.

However, from a design point of view, larger items are not necessarily better, as there are some items that are smaller, and some items that are larger and have too much presence.

Is pink pearl okay for ceremonial occasions?

There is no need to wear accessories at a funeral .

Pearls are a symbol of tears, and their round, white beads are said to represent sadness, so they are considered suitable for funerals.

There is no clear rule regarding the color of pearls, and opinions vary from person to person.

Should wear pearls!

There is no set rule , so you can find a variety of opinions on the internet regarding funeral pearls .

If you wear it

  • Make it into a series. (Because if it is double, it has the meaning of "unfortunate overlap")
  • Avoid long types. (Long means ``sadness lingers'')
  • Avoid single necklaces.
  • The size is 7mm to 8mm ( too large will give a gorgeous impression )
  • Not a deep pink pearl, but a pale pink pearl.

We hope for your reference.

Difference between pink pearl and blue pink pearl

Most pearls undergo some sort of bleaching process to remove stains and dirt, which also bleaches the pink color.

However, as shown in the photo, pearls that are not toned but still have a beautiful pink tinge, and pearls that are toned but have a strong pink color are treated as pink pearls.

Blue cannot be toned through processing unless it is contained in the pearl itself.

While the natural interference color of pearls fades due to bleaching, precious pearls that retain their blue and pink color even after processing are treated as blue-pink.

Even if the pearls are toned, we also treat them as blue-pink if they have a strong blue and pink color.

Of course I recommend Blue Pink Pearl.

This will depend on your preferences, so I recommend that you go to a store and compare.
