First of all, to provide consumers with a simple way to distinguish between good and bad jade: First, tap, let merchants tap jade gently, the clearer the sound, the better. Pure A jadeite has a long echo after being hit. The second is to take photos, you can bring your own strong flashlight or let merchants find a strong light source to observe jadeite under strong light. The warmer and fuller the color, the better the quality. The third is dripping water, you can drop a drop of water on jade. The real A-grade jadeite has a strong water retention ability, and the water droplets on it will not crack immediately, but will be round and convex. Finally, when buying high-priced jadeite, you can pay a part of the deposit first, and then pay the balance after the professional appraisal department has done the appraisal. Next, I will introduce in depth: There are many kinds of green jadeite, which can be divided into lush green, grape green, Mabel Miao, bean green and turquoise green, among which emerald green is the best. A piece of jade is rarely green. Except for the green part, the other colored parts are called "ground". The colors of "ground" are "white, gray, yellow, blue, black, purple and lake green", and the bigger the jade, the better. High-quality jade should have four conditions: good emerald, good water, good land and good perfection. Good emerald means emerald is rich, sunny and harmonious. That is, "strong" but not weak. As green as banana leaves after rain; "Yang" means bright, bright but not dark; "Positive" means emerald green without variegated colors; Harmony is the uniformity of green, and there is no difference in depth. The jargon of "good water", also known as "planting", means that the texture is delicate and thorough, and the luster is crystal clear and dignified but not old. "fertile land" refers to fertile land, lake green land, lotus root starch land, shrimp meat land and white bean land which are the best under the green background. Bean Green Land, Purple Flower Land and Green and White Land followed closely. "Lime land", "taro land" and "excrement land" are the worst. "Perfect" means that there are no cracks, cracks, impurities and other colors, and the weight is appropriate. Natural jadeite is mainly produced in Myanmar, among which "Laoshan Pit" jade and "Shui Pi" jade are the best, and the locals call them "abundant water". The historical origin of the jade bracelet as an ornament, the jade bracelet first appeared in the Neolithic Age and has a history of nearly ten thousand years. Jade bracelets began in Hongwu period of Ming Dynasty and were popular in the late Qing Dynasty and the Republic of China. Jade bracelets are also called bracelets. In ancient times, "bracelet" and "arm ring" were both called "cymbals". "Bracelet" is a ring-shaped ornament worn on the wrist, which is mostly worn by women. The "armband" is mostly used by men and is an arm ornament worn on the elbow joint. "Armband" is rare in modern times. There are two main types of jade bracelets: one is jade bracelets; The other kind is a gold and silver (or gem-inlaid) bracelet. Although there are many kinds of jade materials that can be used to make bracelets, only jade bracelets are the most durable bracelets. Emeralds are rich in color and germplasm, and they are cut into bracelets, which can be described as varied and varied. Even a piece of jade can be processed into different bracelets. Therefore, jade bracelets have been the favorite of China people for hundreds of years. In the early Ming Dynasty, Zhu Yuanzhang sent his adopted son, General Mu Ying, to attack Luquan (China-Myanmar border), which further opened the passage from Tengchong to Yutian. As a result, the jadeite entering Yunnan increased sharply, and a large number of jadeite was imported into the Central Plains. Due to the geographical relationship, Yunnan women prefer jade bracelets, followed by Sichuan, Guizhou and Guangxi. By the end of the Qing Dynasty and the beginning of the Republic of China, jade bracelets had become a necessity for women in Yunnan, Guizhou, Sichuan and Guangxi. When a daughter gets married, there must be no jade bracelet in her dowry. After the death of a woman in a large family, jade bracelets are indispensable in the funerary objects. Among modern China people, ladies from Hongkong, Taiwan Province Province and Macau are the most common China group with jade bracelets. Modern fashionable women have begun to return from the south to the custom of "not getting married without wearing bracelets" a hundred years ago. This back-to-basics fashion concept also quickly spread to the north. The idea of taking the jade bracelet as a token to maintain the feelings of both parties stems from the cultural connotation of the jade bracelet itself. Emerald bracelets are round, symbolizing never ending, eternal rings and circles, harmony and perfection, and endless love. So when men and women get married, they show immortality. Women accompany them with jade bracelets, and go to the marriage hall with their beloved men. Compared with the western diamond wedding ring culture, this oriental wedding custom culture, which expresses endless love with jade bracelets, is more real, appropriate and diverse. Tracing back to the source, in fact, western wedding rings are exactly the same as those in the East, both of which are derived from ring ornaments. The early engagement token of ancient westerners was just an iron ring, which later developed into a diamond ring. Wedding rings are limited to gifts between couples. Oriental jade bracelets not only have the connotation of marriage custom culture, but also are the continuation of family ties. Female elders will pass on the jade bracelet they love all their lives to their daughters and daughters-in-law ... and then pass it on from generation to generation forever. This is the emotional significance of the jade bracelet that never ends. Once upon a time, when the western gem culture penetrated into China, some people accepted the western diamond wedding ring culture. But soon, after rational thinking, people still think that jade wedding bracelet culture is more suitable for China people's customs and concepts, which lasted for nearly a thousand years and once amazed westerners. So why not cherish it in China? In particular, the richness, diversity and uniqueness of jade bracelets are unmatched by any ring. Once the jade bracelet is cut, the golden body remains unchanged, and the family relationship remains unchanged for thousands of years. Although wedding rings also convey feelings, they have many similarities and can be rearranged at will, so their functions passed down from generation to generation will be greatly reduced. In all these cases, people have every reason to choose jade, enjoy jade, and enjoy the warmth and pleasure it brings you. Morphological classification of jadeite bracelets A bracelet consists of two elements: "ring mouth" and "ring strip". According to the shape of the ring mouth, the ring mouth of the bracelet can be divided into round (perfect circle) and oval (oval), and their inner ring mouth and outer ring mouth are consistent and concentric. Elliptical rings are also called princess bracelets. According to legend, Yang Yuhuan, the favorite of the Tang Emperor, made an oval jade bracelet for him to show his nobility and uniqueness, and ordered everyone not to copy it, so he got the title of princess bracelet. In addition, some bracelets have irregular outer rings, so they are called carved bracelets because they have patterns. According to the shape of the cross section of the ring, the ring of the bracelet can be divided into five categories: round, flat, square, trapezoidal and irregular. Almost all jade bracelets in history are round bars. Flat jade bracelets began to rise in Hong Kong 30 years ago. This kind of jade bracelet with flat inside and round outside can fully show the delicate texture of jade. Because the mouth of the inner ring is flat, it has a large contact area with the skin and is more comfortable to wear. Therefore, flat jade bracelets have been accepted by consumers and become the mainstream style of jade bracelets today. When making bracelets, manufacturers will also make bracelets with round terms according to materials, and the effect will be better. Classification of jadeite bracelets There are many kinds of jadeite bracelets, which are difficult to subdivide. According to the principle of "image jade", it can be roughly divided into seven categories: First, plain bracelets: bracelets with only land but no color and flowers are called plain bracelets. There can be many varieties, such as vegetarian skewers made of Polygonum multiflorum Thunb. Plain water bracelet is a colorless and flowerless bracelet with a good head and a transparent bottom. There are ice white, glass white, plain bracelets and so on. Second, floating bracelets: mainly refers to bracelets with orchids distributed in various places. There are many kinds of bracelets, mainly named after local germplasm, such as ice-bottom floating orchid, glass-bottom floating orchid, wax orchid, porcelain orchid and so on. Reading bracelets are top grade, such as glass flower bracelets. Third, colorful bracelets: bracelets decorated with green at the bottom are called colorful bracelets. According to the germplasm of seeds, colored flower bracelets can be divided into several types, such as green flower bracelets on ice. In some areas, green is called "cyan", such as white and blue bracelets and flower and blue bracelets. The top grade is planted well, the color is right, and the color is more. Ice green bracelets and glass green bracelets are relatively rare and expensive. Fourth, the flower bracelet: the color of the flower is purple. The stronger the purple, the higher the price. Any purple jadeite germplasm is not very good. If it can reach the ice purple, it is the top grade, and the whole ice purple is a treasure. When light green and light green are together, they are called multicolored bracelets. 5. Yellow jade bracelets: bracelets with yellow fog and red mist are called yellow jade and red jade bracelets. Although common, yellow fog and red mist do not occupy much. Inferior germplasm is not expensive. Good ice yellow and ice red bracelets are rare and expensive. Yellow, also known as rich color, is sought after by many Cui lovers. Good yellow bracelets are rare and expensive. Six, three-color bracelet: red (yellow), green and purple appear on the bracelet at the same time, called three-color bracelet, meaning happiness, wealth and longevity. Good three-color bracelets are rare and valuable for collection. Seventh, green bracelets: all-green jade bracelets are rare, and it is even more rare to grow well. It is the best in the cuisine, with high price and great collection value. For example, in June, 2000, 5438+ 10, at Christie's auction in Hong Kong, a fully green bracelet with a positive color fetched as much as HK$18.5 million. Health care function of jadeite bracelet Whether jadeite has health care function for human body has not been confirmed by scientific experiments at present, but practical experience tells people that wearing jadeite is good for human body. Some people think that jadeite has "energy gathering function", especially it can store infrared rays. The human body is a biological magnetic field, and the human body is in the big magnetic field of the earth. When the human body wears a jade bracelet, the bracelet will gather and store the energy released by the human body, and also gather and store electromagnetic energy such as infrared rays from around the human body. Because there is a health-care acupoint named "Neiguan point" on the inner side of human wrist, bracelets of various energies will rub and stimulate Neiguan point, thus promoting human blood circulation and benefiting human health. On the other hand, jadeite absorbs and stores energy such as infrared rays, which makes jadeite itself "full". For example, the green color of some jade bracelets has gone up, and it will rise more and more; Some bracelets contain less cotton, and some cotton will disappear, making jadeite more transparent and beautiful. This may be the explanation of what people call "people raise jade and jade raises people". How to choose jade bracelets? Good jade bracelets are timeless and have been passed down from generation to generation. Whether it is for personal use or as a gift, you will pin your true feelings. Therefore, we must use "heart" to choose, and sometimes we must talk about "fate". What you like at first sight can touch your heart, and it may be yours. A good jade bracelet is not necessarily expensive. The so-called "good" refers to the good quality of bracelets. All veteran strings belong to the "good" category, and colorful veteran strings belong to the "better" category. Because of its coarse crystals, loose structure, and easy to mutate and dry for a long time, bean bracelets are not "alive" and have no value of being passed down from generation to generation and collected. It is recommended to be cautious when buying. In fact, it is enough to master one principle when buying jade bracelets, that is, first of all, we must carefully see the "types" of ground seeds, and choose those old ground seeds with delicate structure, cold taste and strong taste, which is the key to determining the quality of bracelets; Then look at the distribution of flowers or colors, which is the measure to determine the price. It is worth reminding that any bracelet with a "copy" on the ground may be "alive" and "good" and cannot be ignored when buying.
