Emerald's A goods are pure natural jade. Only the traditional mild surface acid or surface wax treatment, the structure of the jadeite is not corroded and destroyed.
Emerald B goods, the national jewellery jade standard, optimized jade for the process of processing, after acid leach bleaching, pierced wax treatment of jade. According to the strength of acid leaching bleaching, it can be divided into two types: strong corrosion and weak etch. The strong corrosion optimization of jade is equivalent to the market-named rubber-free B goods. The interior has been greatly damaged.
In the process of processing, the jadeite is treated with strong acid corrosion bleaching and decontamination, and the internal structure of the jadeite is seriously damaged. Then, the gelatinized polymer is filled into the anti-adhesive and filled rubber. Regardless of the optimization of jade or rubberized jade, it should be deliberately treated as destructively treated with jade. The weakly corroded jadeite should be called optimized for jade because it is not destructive.
Glue and color treatment of jade and non-adhesive day color treatment of jade, by acid leaching bleach injection or no injection, and adding jade jewelry called dyes B+C goods.
Emerald C goods, for dyeing jade. Regardless of whether the acid is bleached or not, whether it is filled or not, the artificially colored jade is called C.
At present, the new trend of jade treatment, after strong acid treatment, is not filled with glue, but is filled with wax. The wax filling is optimized, and the filling is processed (B goods), so the national law is exploited.
In addition, water glass (siliceous material) has been used to fill jadeite very early, and the effect is very good. There are also nano-scale aluminum and siliceous materials filled with jade, which are called high-grade B goods.
