上色翡翠就是商家使用化学手段给低质量翡翠染色，一般手段有浸泡，颜料加热煮上色，上过色的翡翠不仅难以分辨，价格也不菲，让消费者蒙受损失。另外化学上色的翡翠长期佩戴也会对身体造成伤害，尤其是染料中的重金属超标的情况更是对佩戴者造成不可挽回的身体伤害。所以，学会鉴别上色翡翠不仅能避坑，还能避免身体健康方面的损害。
1、人眼观察：在太阳光下，我们可以见到翡翠的色调是不是当然、匀称，是不是有色板块根这些，而色跟是分辨翡翠是不是纯天然翡翠的重要环节。但是也是有一些独特的状况，便是一些种较为老的或是是种老的翡翠，有时是难以见到色根的，也有便是，如果翡翠的色调很浮夸、不当然，很有可能便是上色的翡翠了。
2、日光灯灯下观查：我们可以依靠日光灯来鉴别染色的翡翠，将翡翠放到日光灯的下边，细心的观查，要要说见到翡翠的色调展现出去的是鲜红色的，就表明这方面翡翠是人力上色的，如果翡翠的色调不会改变红，会出现二种很有可能，一种是纯天然翡翠，另一种有可能也是人力上色的翡翠，因此 大家就需要依靠别的的方式进一步评定了。
3、紫外光荧光灯管：将翡翠放到紫外光荧光灯管下开展观查，能够非常好的鉴别上色的翡翠，一般纯天然的蓝紫色翡翠在紫外光荧光灯管下沒有莹光的反映，而上色的蓝紫色翡翠的紫外光荧光灯管的直射下，会出现很显著的莹光状况。
4、沸水泡浸：最先我们要提前准备80到100℃的沸水，将翡翠放到沸水里，泡浸数钟头，如果水变色了，表明这方面翡翠是上色的，可是这类方法对新科技上色的翡翠是没有办法辨别的。
5、变大观察：针对一些色调并不是很匀称可是和纯天然的翡翠十分类似的翡翠而言，就需要留意它是不是色上填充颜色了，也就是大家常说的真伪混合色。辨别这一类的翡翠的情况下，大家就必须依靠高倍放大镜了，随后细心的观查翡翠色调重合的边沿，一般来说真、假多色在色彩层面還是拥有 一定的区别的。
我说的这好多个便是有关鉴别染色翡翠的方式，可是每一种都是有它的特性，大家也就只有依据本身的具体情况考虑了，来挑选合适的方式。
Coloring jadeite refers to the use of chemical methods by businesses to dye low-quality jadeite. Common methods include soaking, heating and coloring pigments. Colored jadeite is not only difficult to distinguish, but also expensive, causing losses to consumers. In addition, long-term use of chemically colored jade can also cause harm to the body, especially when the heavy metals in the dye exceed the standard, which can cause irreparable physical harm to the wearer. So, learning to distinguish colored jadeite can not only avoid pitfalls, but also prevent harm to one’s health.
1. Human eye observation: Under sunlight, we can see whether the color tone of jade is natural and symmetrical, whether it is a colored plate root, and so on. Color is an important factor in distinguishing whether jade is pure natural jade. But there are also some unique situations, such as some older or aged jadeite, sometimes it is difficult to see the color roots, and there are also cases where if the color tone of the jadeite is very exaggerated and unnatural, it is very likely to be colored jadeite.
2. Observation under fluorescent lamp: We can rely on fluorescent lamps to identify dyed jadeite. Place the jadeite under the fluorescent lamp and observe carefully. If the color tone of the jadeite shows a bright red color, it indicates that it is artificially colored. If the color tone of the jadeite does not change to red, there are two possibilities: one is pure natural jadeite, and the other is also artificially colored jadeite. Therefore, we need to rely on other methods to further evaluate it.
3. UV fluorescent tube: Placing jade under a UV fluorescent tube for observation can effectively identify colored jade. Generally, pure natural blue purple jade does not reflect fluorescence under a UV fluorescent tube, while colored blue purple jade will show significant fluorescence under direct light from the UV fluorescent tube.
4. Boiling water immersion: First, we need to prepare boiling water at 80 to 100 ℃ in advance, immerse the jade in boiling water for several hours, and if the water changes color, it indicates that the jade is colored. However, this method cannot distinguish jade colored by new technology.
5. Observation of enlargement: For some jadeite that may not have a very uniform color tone but is very similar to pure natural jadeite, it is necessary to pay attention to whether it is filled with color, which is commonly referred to as a mixture of true and false colors. To distinguish this type of jade, one must rely on a high-power magnifying glass and carefully observe the edges where the jade tones overlap. Generally speaking, there is still a certain difference in color between true and false multiple colors.
The many methods I mentioned are related to identifying dyed jadeite, but each one has its own characteristics, so everyone can only choose the appropriate method based on their specific situation.
