Identifying the purity of jadeite B+C involves a meticulous and professional job that requires specialized knowledge and skills. Below we will provide you with some basic reference guidelines to help you identify B+C jadeite products.
First of all, it is very important to understand the grading classification of jadeite. Generally speaking, jadeite is divided into three grades: A, B, and C. A product refers to natural raw jadeite, which has not been modified by any human processing;B product is pickled beeswax-treated jadeite, and the essence of its natural ore has not changed;The C product is filled and dyed, which changes the essence of the original natural ore. The so-called B+C product is dyed on the basis of B jadeite. This grade of jadeite may be more vivid in color, but it does not have the true value of high-quality jadeite.
For the identification of jadeite B+C products, the most intuitive and effective method is to observe with the naked eye. The jadeite can be placed in bright light and the inside of the jadeite can be carefully viewed. If there are starry, cloud-like, and uniformly colored smudges inside the jadeite, and these smudges are very close to the surface of the jadeite, then it is likely to be a B+C product. Because the dyeing process of B+C products can often only penetrate the surface layer of jadeite, and cannot reach the interior of jadeite stone.
Secondly, it can be judged by the weight of the jadeite. Because B+C products with beeswax treatment and dyeing treatment are usually heavier than A-grade jadeite with the same volume due to substance injection.
In addition, B+C jadeite is more sticky and slippery than A-grade jadeite when it comes into contact with ** or tongue, which is because the surface of B+C jadeite has changed after being filled with beeswax.
Finally, there is also the option to turn to a professional gem laboratory. These institutions have professional equipment and appraisers who can more accurately judge the grade of jadeite. However, it should be noted that the cost of the appraisal is usually high, so you need to consider whether to conduct a professional appraisal according to your financial situation.
