Jade is highly praised for its vivid green color, but sometimes the color is a result of dyeing. Dyeing together with bleaching and impregnation is the most common way of jade treatment. Today we are going to specifically focus on jade dyeing and to shed a light on such fundamental questions: how to tell if jade has been dyed, what are the reasons for dyeing, if this treatment is stable, and how much the dyed jade is worth.

Dyed jade is hard to identify. Ideally, dyed jade has its own mark on the trade – it is Type C jade. Dyed jade treatment can be spotted under UV light or magnification. Inhomogeneous concentration of dye can be observed under a great magnification. Only gemologists can identify dyeing for sure.

Lavender, orange, and white colors of jade are extremely rare; however, they can be absolutely natural! Sometimes these incredible colors occur as a result of dyeing.

Even more, the coloration of jade is often streaked or mottled, giving jadeite gemstones an interesting visual texture that carvers can use to create imaginative and intriguing effects. Learn how dyeing can be spotted in jade and how to become sure of jade coloration.

How Can You Tell if Jade Has Been Dyed?

Dyed jade identification is a challenging process for even professional gemologists. Basic gemological methods are usually not enough to tell the treatment for sure.

Further, you will find basic tips which will help you to understand whether the jade is dyed or not. However, in the case of jade, it’s always better to ask a gemologist.

Dyed jade should be marked as Type C jade on the trade. To identify treatment it is necessary to use UV light – dyed zones will glow. Also, dyed jade can be spotted due to the green pigment concentration between natural jade tiny crystals. Beads of jade coated by dye will have chips around the bead’s hole.

Just a few words regarding why the jade is so severely treated. The reason for jade treatment is its high popularity in Chinese culture.

The demand for jade is extremely high and continues to grow each year. Jade is a spiritual stone with significant meaning that’s intricately woven into Chinese culture for thousands of years.

It’s noteworthy that modern gemologists use the word “jade” as a generic term for both nephrite and jadeite minerals. These gems have been linked throughout history.

The term jade has also been applied to several gems and ornamental materials that resemble jade, and even some man-made equivalents resembling jadeite and nephrite.

The best jade is jadeite jade. And it’s correct to use jadeite or nephrite jade terms instead of general jade. So pay attention to how the trader calls its material.

The Jade market is a separate world from all colored stone trade. Jade treatment is so common that it has its own classification:

Jadeite jade types Treatment type
Type A jadeiteTechnically it is completely natural, but it can be dipped in wax or treated with a surface coating of wax. Wax coating is not considered as a treatment as it is a traditional finishing process for jade.
Type B jadeite Bleached and impregnated jadeite.
Type C jadeiteDyed material. 
Type B + CA combination of dyed and impregnated material.
Jadeite jade type and type of treatment

The GIA (one of the most trustworthy gemological labs in the world) reports identifying jade treatments with generic terms like “dyed,” “impregnated,” or “luster-enhanced.”

  1. step: to tell if jade is dyed is to see the trade labels. If it is Type C jade – it stays that jade is dyed.
  2. step: is to examine jade under magnification. The green pigment used for enhancement tends to concentrate between tiny pale crystals of jadeite. 
  3. step: is to check the area around the hole of the bead. Inhomogeneous coloration will be also clearly observed in this zone.
  4. step: If the jade is coated with green dye (the cheapest way of jade treatment), small chips can be spotted on the zones exposed to mechanical friction (prongs, claws, edge of bezel mounting).
  5. step: requires a source of UV light or blacklight. Dyed zones glow under UV light, while natural untreated jadeite jade stays inert. Please, be careful with this method because waxed natural jadeite (not considered as treated or dyed) can also glow occasionally.

What Does Dyed Jade Look Like?

Dyed jade looks identical to untreated material. Methods of jade enhancement have evolved over the centuries. Some signs or dyeing can be occasionally observed. If you can spot just one – jade is treated for sure.

Dyed jade looks absolutely the same as the untreated one. Dyed jade has an apple-green or lush-green color with white and grayish-white veins. Dyed jade has a local concentration of saturated green pigment between the jade crystals, which can be observed under magnification. 

Here are the signs of dyed jade:

  • Zones of dye concentrations. Dyed jade looks like the green color originates between pale crystals, while crystals stay white or whitish-green.
  • Chips on the surface, around the bead hole, or on the zones which are in contact with metal.
  • Green zones glow under UV light.

Why is Jade Dyed?

Why is Jade Dyed?

Jadeite jade’s three most important qualities are color, transparency, and texture. Dyeing can improve two of them (both color and texture) and significantly increase the price.

Jade is commonly dyed to improve the pale color to the highest valued vivid-green and, as a result, to increase the jewelry piece price. The porous structure of natural jade soaks the coloring agent quite well, making the identification of the treatment process complicated.

Dyeing can alter the color of pale or grayish jadeite, and more rarely, nephrite. This is accomplished by adding a green dye to the impregnation material. Lavender jadeite might be treated with dye alone, and the result can be undetectable.

Carvings and bangles might be partially dyed to imitate the natural variations seen when a highly skilled artisan incorporates those variations into the final design.

Dyeing can be used to introduce orangy brown colors, imitating the skin, or oxidized outer surface, of a boulder. The result is virtually indistinguishable from the natural coloration that results from concentrated iron compounds.

A trained gemologist can sometimes detect this treatment using magnification and a hand-held spectroscope, but advanced technologies are necessary to produce the final report regarding the treatment.

TIP: Geodes are another rocks that are often dyed. Find out how to spot dyed geodes in the article below:

What is Dyed Jade Worth?

Dyed jade is far cheaper than natural ones. The price difference can reach four-digit values. That is why it is so important to know how to spot treatment.

The price for dyed jade is the lowest among all other types of treated jade. Depending on the size of stone and kind of jewelry (be it bangle or carving), the price for dyed jade doesn’t exceed 50$, compared to the natural jade, where the price per carat (0.2 gram) can be more than 1000$.

The most traditional jade piece of jewelry is a bangle (rigid, ring-shaped solid bracelet carved from a solid piece of stone). It’s possible to find a dyed jade bangle for about 15 dollars.

The price for dyed jade is low when the treatment is clearly indicated. It’s crucial to fairly disclose all the treatments.

Is All Jade Dyed?

Not all jade is dyed. There is a lot of high-quality material which doesn’t require color enhancement. Jade is impregnated, bleached, or wax-saturated far more often than dyed. If the jade is called Type C, it means that it is dyed in order to improve its appearance.

How Long Does Dyed Jade Last?

The dyed jade color (of course, depending on the manufacturer) is quite stable and can last for years if handled with care. Exposure to chemicals and household cleaners or heat from a jeweler’s torch can have negative effects on jade appearance (including artificial coloration) and durability.

How do You Get the Dye Out of Jade?

The dye can be removed from the jade by wiping the stone with a cotton cloth soaked with a solvent like acetone or if placed for a few hours into a bleaching solution. However, we do not recommend you to do this, as the whole piece of jewelry can be spoiled.

Conclusion

Jade is commonly treated by various methods. They are impregnation, bleaching, and dyeing. It is quite challenging even for professionals to spot them.

Dyed jade is marked as Type C jade on the trade. 

  1. To identify treatment, it is necessary to carefully observe the jade under magnification to find zones of pigment concentrations.
  2. UV light can come in handy while trying to spot dye. Dyed jade can sometimes glow under the black light.
  3. Also, beads of jade that are coated by dye will have chips around the bead’s hole.

To make a final conclusion regarding the treatment, we highly recommend consulting with professional gemologists.

TIP: Using UV light is necessary when identifying dyed jade. Testing with UV light is also necessary when trying to identify real and fake ambers. Find out more about how to spot fake amber in the article below:
