Enhancement and treatment of gemstones: refers to all methods used to improve the appearance (color, purity or special phenomenon), durability or usability of jewelry and jade except cutting and polishing.

Optimization processing is divided into two categories: enhancement and processing.

Optimization refers to the traditional and widely accepted optimization method, which shows the potential beauty of jewelry and jade. Such as the bleaching of pearls.

Treatment refers to non-traditional and not yet accepted optimal treatment methods. For example, the dyeing of jade.

Directly use the optimized name of jewelry and jade, without marking the identification certificate and logo of jewelry and jade.

When naming the processed jewels and jade, the names of jewels and jade cannot be used directly, and the following rules should be followed:

(1) Add the word "disposal" or indicate the disposal method in brackets after the name of the corresponding jewelry and jade. Such as sapphire (treatment), sapphire (diffusion), jadeite (treatment) and jadeite (bleaching and filling). The specific treatment method can also be described before the corresponding jewelry and jade names. Such as: "spreading sapphire", "bleaching, supplementing jade".

(2) The specific treatment method must be stated in the jewelry and jade appraisal certificate.

(3) Under the current general appraisal technical conditions, if it is uncertain whether it has been treated, it may not be indicated in the name of jewelry and jade, but it must be marked and explained in the following ways. For example, "not sure whether it has been-treated" or "possibly treated", such as blue topaz of unknown origin, may be marked "not sure whether it has been irradiated" or "possibly irradiated".

(4) The processed artifacts can be directly named by their basic names.

It should be said that the healthy, prosperous and rapid development of China's jewelry market is also a process of establishing, implementing and perfecting the national naming rules for jewelry and jade. Only by standardizing the naming of jewelry and jade can we standardize the market, put an end to counterfeiting and let consumers build confidence and buy with confidence.
