Jade is a precious gem of the East and has the reputation of the king of jade. Jewelers list jade and emeralds together as the birthstone of May, a symbol of luck and happiness. In the Greater China region, especially in Japan, Hong Kong, Macao, Taiwan and Southeast Asian countries are deeply loved by people. In recent years, the jewels boom, jade is the leader in gems.
Emerald was originally a bird name in China. Emerald is a red-feathered bird. Cui is a green-feathered bird. It is gradually merged in two words, specifically a bird with brown in blue-green. The reason why jadeite was transferred to the jade, and specifically refers to a kind of jadeite containing sodium aluminum silicate, because this jadeite is often in a state of uneven color, sometimes accompanied by red and green colors on a light foundation. The block, its color is like a beautiful emerald bird.
Jadeite has a hardness of 6.5-7, good toughness, and is not easily broken after being hit hard. Some compressive strength even exceeds steel. The color of jade is high, and the pure jade of chemical composition is white. When the component contains metallic pigment ions, "green, red, purple, yellow, gray, black" will appear. The red is called ç¿¡, the green is called ç¿ , among all the colors, the most expensive and the most valuable is the beautiful green. However, if on a jade jade, red, green, purple, and yellow coexist, it means Fu, Lu, Shou, and Xi, then it is a jade with a high value.
More than 90% of the world's jadeite is produced in Myanmar. The color of the jade is exquisite, the texture is fine, the hardness is high, and the toughness is good. It can be used to sculpt jewelry and various handicrafts. Around the Ming Dynasty, the emerald was favored by people after it was introduced to China by the Myanmar store. The jade carvings are superbly produced. In the folk, there are jade cucumbers and exquisite pagodas. The jade products in the palace are extraordinary, showing the skill of the craftsman. According to the data, there are many jade products in the funeral of the Empress Dowager Cixi in the Qing Dynasty. There are 2 jade watermelons at the foot, green skin red peony, white seed black silk, value 5 million two silver, 4 jade melons, 2 Only white-skinned yellow seed powder, melon, 2 is only green-skinned yellow melon, worth 6 million two silver; head with handle lotus leaves, leaves are covered with green tendons, such as natural weight 23 two, worth 2.85 million two silver. In addition, there are 10 emerald peaches, the peach body is green, the peach tip is pink, and the peach is the same; the jade green vegetables are 2, the green heart is covered with a green beet, and there are 2 yellow wasps on the leaves. .
Jadeite is also called jadeite, the name of gemstone jade, and its mineralogical name is sodium pyroxene. In the study of artificial jade, it was confirmed that pure smectite is colorless, and only after adding "chromium" can green appear. Therefore, the natural jade belt does not have green color, so it is seen that there is no chrome mixed inside when the jade is formed, and the more chromium is mixed, the greener the jade. However, the amount of chromium contained in the ring or other jewellery processed from jadeite obtained from mines or rivers has been fixed, so the green of jadeite is unlikely to increase. However, in some cases, chromium in jade can produce a chemical reaction, which causes a small amount of diffusion of chromium, which is why people think of "long green". The jadeite that produces "long green" is mainly jadeite with jade necklace, jade bracelet and jade enamel. The reason is that the human body has a certain temperature and is also prone to sweating. The sweat has acid or alkaline components. These components can penetrate into the microcracks of the jade, some of which may react with the green chromium ions. Or dissolve the chromium ions that have been consolidated in the jade to produce migration, so that the green is "long". In fact, there is no change in the content of green chromium produced in jade, only trace amounts of chromium are diffused or migrated.
Orientals like the beautiful colors and warm texture of jade. In Hong Kong, Taiwan, China, Japan, South Korea and other areas, jade is very popular, and even more than other precious stones.
Different grades of jewelry have their own consumption layers and consumption trends. The low-grade jade can be used as a gift for each other, and the price is several hundred yuan. Mid-range jade can be used as a gift, or you can buy and sell a piece of jewelry for yourself. Most high-end jadeites are purchased by wealthy businessmen. The boutique is the rare treasure of the rich.
The color of jade is very important and is the decisive factor affecting the value. To evaluate the quality of the color depends on whether the color is positive, whether there is color cast or other color, and the color is as good as possible. The second is to look at the shade of the color, the color is suitable for the light, the color is too strong, it is very heavy, the color is too light, and it is too tender. Again, look at the uniformity of the color, and the color is uniform. The color distribution is uneven.
It is easier to judge whether the jade jewelry has cracks, size or shape. No cracks are good, small cracks are second, and large cracks are more frequent. Therefore, in general, the price of a good jadeite is high, and the price of a little bit of a problem is lower. From the point of view of the preservation of value, a jade with good aspects is rare and the most worth buying. However, it must be stated that the jadeite is best in A, which is a natural jade without any artificial modification. This natural jade does not change with time, it can be permanently preserved and worn, and it also has a collection and preservation value. The potential for appreciation.
