How many types of jade are there? How many types of jade are there? What are they?

The fine jade is moisturizing, transparent, greasy, and warm when pinched in the hand. The main way to distinguish the true from the fake is with the help of a magnifying glass or microscope, which can see that the inside of the jade is a fiber interwoven structure with fine particle size; Whereas artificial glass has no structure, bubbles can be seen. You can also carve with a knife in an inconspicuous place of jade, and what can be carved must be fake jade, and what cannot be carved is real jade.

As the saying goes, "** priceless jade is priceless". Because the high-grade Hetian jade is becoming more and more scarce, each kilogram can reach tens of thousands to hundreds of thousands of yuan, and the general Qinghai white jade, Russian white jade and other kilograms are only thousands of yuan, so some people mix this with Hetian jade. The minerals of these jades are basically the same as those of Hetian jade, but the surface color is darker and not softer, and it will be darker over time.

The old jade and the new jade can be identified from two aspects, the surface of the old jade has a layer of oxidized jade skin, commonly known as "pulp", like the skin of autumn pear, and the natural color of the jade has obvious differences, and the new jade is not. Judging from the subject matter of carving, ancient jade is a symbol of rank and power, with mythical flowers, birds, and figures, such as dragons and phoenixes. And the new ones are generally auspicious themes.

Since ancient times, jade has formed an indissoluble bond with Chinese culture. In the hearts of Chinese, jade is a symbol of good fortune, so Chinese like to use jade to protect themselves, keep safe and ward off evil spirits, and even use jade to accompany burials; Westerners, on the other hand, mainly appreciate the elegance, mystery and romance of jade. Classification of jade:

Jade can be divided into nephrite and jadeite, which are two different minerals. Nephrite jade has translucent white, yellow, green and black colors, and the color is evenly distributed. As for jadeite, it is mainly white, purple, yellow and green, and the uniformity of color distribution will vary among different germplasms. The vast majority of nephrite jade produced in China is the most precious piece of nephrite, with its delicate texture and white color, and many exquisite jade artworks are carved from nephrite.

Jadeite is mainly produced in Myanmar and is rarer than nephrite. Since jadeite is superior to nephrite in terms of jade quality, color and price, jadeite jewelry in the market is mainly made of jadeite, and consumer demand is also very large, so we will focus on jadeite - jadeite.

Appreciating jadeite should pay attention to color and germplasm, which can be subdivided into color, transparency, clarity, cut and cracks, and generally start with its color. Color Color is the most important factor affecting the value of jadeite, and the color of jadeite can be evaluated from the following four domains: To be pure:

Pure refers to the ratio of the main color and the secondary color of jadeite, taking green jadeite as an example, pure green is the best, green with yellow or blue is inferior, and gray is the worst. To be the right shade: when it comes to the depth of the color, of course, the thicker the better, but too strong the color will cause the opposite effect and reduce the quality of the jadeite.

Be distinct: the brighter and brighter the color of jadeite, the more attractive it is, and the more proportion of gray or black it contains, the darker the color To be even: the more evenly distributed the color, the better, and the higher the value.

Transparency The transparency of jadeite affects the refraction of light, which affects the overall beauty. When the light enters the transparent and delicate jadeite, it will reflect a beautiful light, making people feel the crystal transparency of the jadeite, which greatly increases its beauty. On the contrary, if the light encounters a jadeite with low transparency and rough texture, it will reflect the dull light, which will greatly reduce the attraction of the jadeite.

Clarity Clarity refers to the imperfections contained in jadeite, mainly white and black, which are caused by the inclusion of other minerals in jadeite, and black blemishes are relatively more eye-catching than white. The fewer impurities in jadeite, the better. Cut The processing of jadeite products is divided into two categories: bare body and carving.

In addition to the absence of cracks, the proportion of the cut, the thickness of the product and whether it is symmetrical are also very important, which can affect the appearance of the jadeite finished product. For example, a well-cut egg should not be too thick or too thin, and the divination should be in the center and the proportions should be moderate. The evaluation of flowers is mainly based on their beauty and the fineness of the carving, and usually cracked jadeite will be treated in a carved way to cover up its imperfections.

Cracks Cracks can greatly reduce the value of jadeite. If there is a crack in the jadeite ornament, the slightest collision may crack along the crack. Therefore, extra care should be taken when buying jadeite ornaments, generally speaking, it is easy to detect the presence of cracks by irradiating them with a flashlight.

There are nephrite jade and jadeite jadeite.

Nephrite is a traditional Chinese jade material, and the name of jade comes from nephrite, which is often referred to as "Hetian jade" because the best jade is produced in the Hotan region of Xinjiang.
