The jade has any flaws, but whether there are larger cracks, will it affect the durability of the jade. If it is a naturally formed fine stone vein pattern, as long as it does not affect the permissible range of the appearance, but if it is a crack that crosses more than half of the jadeite or obvious black inclusions, it will have a significant impact on the price of jadeite.

The world’s gem-grade jadeite is mainly produced in Myanmar, and it is also produced in other countries, such as China, Япония, Guatemala, Mexico and California, и т.н., but it is not large in quantity and poor in quality.

The jadeite is the darling of the Chinese jewelry market, with many styles and large sales. Those who have come into contact with jade jewelry must have heard the so-called A-goods, B-goods and other commercial terms. The four letters A. Б. C. D are used to represent the meaning of jade. It was originally a common lingua franca among businessmen. Because it is easy to understand, it has gradually been widely used in the jade trading market.

Goods A, completely natural jade, тоест да се каже, after the rough jadeite is excavated, it has not undergone any chemical treatment or added any foreign substances. It is a finished jadeite that has only been cut and polished, regardless of color or texture. It is natural.

Goods B, the rough jadeite is soaked in strong acid to remove impurities, and other substances (generally resins) are usually poured into it to strengthen the loose structure of the jadeite after being eroded by the strong acid. As long as the jadeite treated with acid is called B goods. But goods B has not been dyed, so the color is still natural. The price of goods B after treatment is very different from the price of goods A with similar appearance, and may even differ by more than tens of times.

Product C, dyed jadeite, its color is artificial rather than natural. Although the composition of product C is still jade, the price is lower than that of product B, because the color of jade is the most important factor in determining the price. .

B+C goods, after the processing steps of B and C goods, това е, the jade that has gone through two steps of pickling and dyeing, is called B+C goods.

Goods D, substitutes for jadeite, as long as they are not jadeite but look like jadeite, items that are regarded as jadeite are called goods D. Not all substitutes are artificial synthetic imitations, and some look similar to natural jadeite Ores also belong to this category, such as green chalcedony (commonly known as Australian jade), dyed quartz, sulphur jade, и т.н.. В допълнение, synthetic imitations include plastic products and stained glass.
