wholesale sterling silver rings with stones Smart Eye Recognition: Treatment of Jade (Parte 1)

Pubblicato il da Kingjy

Because jadeite occupies an important position in the Chinese jewellery market and its sales volume is large, some people are thinking about treating inferior jadeite to improve the appearance of jadeite in order to achieve a higher price.

The type and color of jade is the most important factor affecting the price, so the treatment of jade is mainly to improve these two textures. Undercut filling and B-cargo filling and filling treatments are mostly used for the emerald green color of jadeite itself, which sells well. Perciò, the treatment is done to improve the cultivation of jadeite; while the dyeing and heat treatment are the result of artificial coloring.

This is the most common product in the jewelry market, especially jade ornaments such as egg noodles, saddle ring noodles and carved Buddha statues. This kind of jade jewelry must be back covered. The so-called “back cover” is to use metal to cover the back of the jade. Completely sealed, the finished product is completely invisible to the back of the jade, because the bottomed jade is really the part of the jade, only the outermost layer of the jade is very thin, and the bottom is filled with glue, so of course the metal inlaid Cover all the back. Tuttavia, because the outermost layer of jade is usually without other chemical treatments, the industry generally still tells consumers that the jade is a commodity A, but the industry should clearly inform that it is a bottomed jade when selling it. The dry green species mentioned above are most commonly used to make this jade jewelry, because the color is very green and the cut is very thin, which greatly improves the light transmission, and is made into egg noodle saddles or Guanyin statues and inlaid into jewelry. The price is low and it sells very well.

The dyeing process is the so-called C cargo, in which the jade is injected or soaked with dye to make the jade appear delicate and emerald green. The dyeing treatment in the past will fade after wearing for a long time. Negli ultimi anni, the dyeing agent has been continuously innovated, and there is less fading problem. The dyeing treatment can be easily detected in general laboratories, so the probability of selling dyed jadeite in jewelry stores is not high. It is a stall area with uneven quality, so be especially careful. Inoltre, there is another way to coat the color on the jade by spraying or painting, and it can be scraped off with a knife, commonly known as “scratching jade”.
