The difference between sapphire and green white jade

Sapphire is the largest component of nephrite. Its material composition is the same or similar to that of white jade. The cause is the same as that of white jade. It is a cause of contact metamorphism. It is only due to the trace element iron. Sapphire should be worn and maintained in a collision with hard objects, worn frequently and always rubbed.

Sapphire is from light cyan to dark blue, and there are many kinds of colors. The ancient books include scorpion green, nasal green, crab shell green, and leaf green. Modern colors vary in color, and there are also light green, dark blue, green blue, gray green, dark gray green and so on. The most common sapphire in the jade and jade. In recent years, I have seen a kind of green jade, which is light green.

According to the color, luster and splitting degree of the jade, the sapphire can be divided into three grades.

First grade sapphire:

The best quality, the color is pure cyan, the texture is fine and tough, the oil is shiny, the structure is perfect without obvious cracking.

Secondary Sapphire:

Medium sapphire, sometimes with some yellow and green in the color cyan, the texture is delicate and tough, it is oily and shiny, and it will be somewhat cracked but not serious.

Third-grade sapphire:

The quality of the sapphire, its color cyan often comes with many other variegated colors such as green, gray, yellow, etc. The texture is fine and tough, with a waxy luster.

Sapphire is the largest component of nephrite. Its material composition is the same or similar to that of white jade. The cause is the same as that of white jade. It is a cause of contact metamorphism. It is only due to the trace element iron. Among them, some of the sapphire has a stronger interweaving structure and better toughness.

The difference between sapphire and green white jade

Sapphire contains a wide range of varieties, from blue and white to dark dark green, the color span is large, but also because of this color span can be subdivided into white jade, sapphire, green and green color is also known as green jasper. Sapphire is the highest hardness of nephrite, also known as steel jade, but the color is not as good as white jade.

Qingbaiyu: Between the jade and the white jade, a lot of good white jade, not carefully identified, really thought it was white jade. From the perspective of engraving, there are several nouns, "Haipai, Sugong, Yangzhou workers...", and many of them are Fujian workers. Fuzhou is famous for wood carvings and lacquer wares. Because Fuzhou Lianjiang Luoyuan is rich in Shoushan Stone, Stone carvings will not be bad.

Sapphire identification has a clever method

A look at its texture:

Sapphire still contains a small amount of impurities, the internal grain is clear, there is a certain stone pattern for identification, and the texture of the fake sapphire is like a painting, there is no natural feeling.

Second, look at its brightness and luster:

The texture of the sapphire is very detailed, the feel is very warm, and the gloss is soft. If you put a piece of jade in your hand, do you feel heavy, and then see if the sapphire's luster is waxy and there are no bubbles inside. Feel if you feel warm with your hands.

Three is not cheap:

Hetian Qingyu is still a scarce resource of Hetian jade. Even if the value is lower than that of white jade, it is also a precious jade. Don't believe that the small traders use the high-priced white jade to set off the cheapness of the jade, which must be forged similar jade.

Sapphire, especially Hetian Qingyu, is a scarce resource after all. With the mining of sapphire, the output of sapphire will continue to decrease, so even if its price is lower than white jade, it is a precious jade. If you encounter a sapphire that looks good in quality, but the price is low, then it is likely to be a counterfeit, so you have to be careful.
