The three types of jade that are most likely to mutate, so buy with caution!

Variants are another headache besides authenticity, and are even scarier than fakes. Because if you buy a fake, you can return it based on identification, but variants cannot be returned, and you can only bear the loss of a greatly reduced value. So what exactly is the matter with jade variants? Which jade is more likely to mutate?

In terms of jadeite's structure, jadeite is a stone polycrystalline aggregate that reaches the jade grade under geological action . It is mainly composed of pyroxene minerals , mainly jadeite . Jadeite is very stable and will not be corroded even when washed with strong acid. Therefore, the essence of the mutation is not that the jadeite has changed, but that other substances in jadeite have changed.

According to the rich experience of industry professionals , jadeite variations can be divided into three main types.

0 1

Oily green jadeite

The color of oily green jade is a secondary color, which is caused by the Fe2+-containing clay material that fills the gaps or cracks in the jadeite mineral grains. This type of jade raw stone has been soaked and buried in the black mud at the bottom of lakes or rivers for a long time. It is mainly caused by the penetration of foreign substances along the surface of the jade rough material and the open cracks near the surface.

Fe2+ ​​is usually unstable when exposed to air and is easily oxidized into Fe3+-type limonite minerals, and the color will change from the original dark green or dark green to yellow, brown or red. This is the reason for the Youqing variety.

White jadeite

Many white-bottomed green jades on the market are new pit materials, also known as "mountain materials". Mountain materials have not undergone natural transportation and washing. Compared with water stones, they have a loose structure and are tender . This finished product usually has a waxy luster, and the sound is dull when tapped, which sounds similar to B goods. The wax peak tested with an infrared spectrometer is very strong, and it usually reaches the bottom.

This kind of jade is usually soaked in wax . Wax, as an organic matter, is unstable in the air and easily turns yellow, thus mutating. It is the same principle as silicone mobile phone cases that turn yellow and gray after three to five months of use.

Young jadeite

The type of jade refers to the density of jade. Jade of tender quality usually has coarse grains and a loose structure . When jade is waxed, its structure tends to absorb more wax. The wax turns yellow when exposed to the air, thus mutating.

This also indirectly illustrates the importance of the quality of jade . As the saying goes, experts look at the quality while laymen look at the color. It's not that the color of the jade is bad, but that you have to buy the color of the jade under the condition of good quality. Jade of poor quality will always have defects and problems of one kind or another.
