Color root. Distinguish and optimize jadeite by looking at the color roots, and carefully observe the surface of jadeite. There is no optimized jade, and there are strong color roots on the surface, which are embedded in the jade meat, so people can see it at a glance. After optimization, the color roots on the surface are inevitably a little floating, which seems a little shallow. Structure.

Look at the surface gloss, smoothness and smoothness. Natural jadeite has bright luster and smooth and round surface, while B and coated jadeite have rough surface and weak luster.

Look at the water head: the "water" of jadeite refers to its transparency, also called water head. The water of jadeite is related to the structure of jadeite, which means it is related to "species". It is also related to the content of impurities, such as the old variety of jadeite water, less impurities, uniform particle size and high purity.

Can the optimization in the national standard of jadeite be understood as optimization and high B universality?

1, only natural A-goods jadeite will be marked: commonly known as "A-goods". If the words "optimization" or "treatment" are written, it means that it is not natural, and it may be B goods or C goods. It is best not to buy such jadeite.

2. According to the national standard of jewelry and jade, the best product of jadeite is jadeite which has undergone acid leaching, bleaching and waxing during processing. According to the strength of acid leaching bleaching, it can also be divided into strong corrosion and weak corrosion. The jadeite with strong corrosion optimization is equivalent to the glue-free B goods on the market. Its interior has been seriously damaged.

3. The jadeite raw materials that can be used to make jadeite B goods are generally jadeite with more impurities and loose structure. After being soaked and corroded by strong acid and alkali, some substances are brought in and brought out, and corrosion is formed on the surface and inside along the mineral crystal, resulting in internal communication cracks and surface system of canals, and the internal cracks are serrated tensile cracks.

Distinguishing jadeite from optimized jadeite

Identification of Emerald B (1) Glossy: The polished surface of Emerald A is glassy; B goods are resin luster after being soaked in strong acid and filled with glue. After being filled with glue and polished, resin luster spots can still be seen, and the overall resin luster is mixed with glass luster.

The key to distinguish between jadeite optimization and jadeite treatment mainly depends on whether jadeite has glue. As for artificially colored jadeite, although it has not been bleached or glued, it can be judged as dyed jadeite only according to its unnatural color.

A common optimization method of jadeite: heating-jadeite can deepen the color of the material by heating, making it more brown and obsolete. Waxing-usually used to hide surface cracks and improve surface gloss.
