Grade A Natural Jadeite Jade vs Treated Jade Grades B and C

Grade A Natural Jadeite Jade vs Treated Jade Grades B and C

Jadeite jade is categorized into three grades: A, B, and C. These grades are used to rate how different jadeite jades were altered and treated. There is a great difference between the grades even though all three are real jadeite. Depending on the alteration, the value of the jade can decrease significantly since it is not natural anymore.

Grade A, B, and C Jade

Jadeite jade has been historically subjected to various enhancements so, in recent years, to help determine the naturalness of jadeite jade, experts have come up with a grading scale for evaluating a piece of jade. Previously we also talked about jade imitations where we distinguish grade A from fake jade, to get a recap click here. Furthermore, these grades were created because there were so many dishonest businessmen who altered jade in order to sell it at a greater price than it was originally at and ruining the jade’s naturalness. When we talk about this grading scale, we are talking about jadeite jade, but nephrite jade also has its own grading. From now on unless specifically told, when we refer to jade, it is jadeite jade. 

The table shows grade A natural jadeite indicates that it has not been subjected to any form of chemical treatment and grades B and C might not be safe to wear.

Grade A means that the jade is completely natural with absolutely zero treatment besides cutting and polishing. Polishing, also known as waxing, is a common practice and does not devalue the jade piece as it is only a thin top layer. This is the highest natural quality jadeite there is. 

Grade B means that it has been treated by being bleached or soaked in hydrochloric/sulfuric acid. This is done to clean the inside of impurities and inferior color. It has five to ten percent the value of grade a jade. It is often hard to tell so when buying make sure to ask the vendor whether the jade has been treated.

Grade C jade has gone through all the treatments mentioned for grade B but is also dyed to improve the color or consistency of the color. This is detrimental to the jade as it weakens its structure and could result in further treatment like injecting it with polymers to make it stronger again. This grade of jade has very little to no value. 

At Dahlia, we only offer grade A jadeite jade, so you can buy with confidence. When buying grades B or C, you may experience fading of color or even skin irritation due to the chemicals used to treat the jade so it is not recommended to wear these jades. Make sure that you are buying jade jewelry from a reputable company to ensure that you are getting the real and natural thing to ensure that there won’t be any dangers in wearing altered jade.

Overall, jades aren't just jadeites or nephrites; there are different grades as to how they were treated and why they look the way they do. Similarly, grade A jade can be worn with confidence because it retains its natural vibrant green color and is safe to wear. Others, such as B and C, have textured damage and more of a color change, making it unsafe to wear. Grade A is only worth your money in our opinion because it is completely natural with no treatment. It is also the finest jadeite available.
