Jade, also known as jadeite, jadeite, jadeite and Burmese jade, is a kind of jade. Jadeite is a polycrystalline aggregate of stones formed under the geological action and reaching the jade level. In ancient times, jade was a bird that lived in the south. Its coat color is very beautiful, usually blue, green, red and brown. Generally, the male of this bird is red and called "Fei", and the female is green and called "Cui".
Recognition experience
1. color: different color grades of jadeite are closely related in value. When judging and evaluating jadeite, we must distinguish its colors, mainly red, green and purple. Green in monochromatic jadeite, elegant and pure purple and red are all high-grade colors in jadeite, especially green is the most expensive. Emerald green should be strong, sunny, handsome, straight and harmonious. Ruby green, glass green, bright green and seedling green are the best greens.
2. Layout: The layout of jadeite is the staggered layout of phenocrysts, which refers to the layout formed by the metamorphosis of fine fibrous mineral crystals interlaced around bright granular phenocrysts. In jadeite, there are small lumps of small white flowers composed of opaque or slightly bright white fibrous crystals, so they are called "stone flowers" or "stone brains".
3. Water head: Water head is the brightness of jade. The higher the water head, the better and more precious the germplasm is. You need to be very careful when investigating the head of jadeite, because the brightness is related to the thickness of jadeite itself. In addition, special attention should be paid to jade products with limbs, such as the center of the product is hollow. There is also the need to pay attention to agate products, because the brightness of agate is also better, so some people paint agate to imitate jade. In Hongkong and Taiwan Province, the brightness of jadeite is also divided into "Tong", "Fang", "Tou", "Bing" and "Ying", among which "Ying" is the top grade.
4. Seed pits: The seed pits of jadeite are composed of layout and texture, and jadeite is composed of small crystals. The smaller the grain, the finer the texture, the better the transparency and the better the polishing effect. In the jewelry industry, pits are divided into old pits and new pits. The old cellar is bright and moist in color, integrated with the ground, with high transparency and the best quality. Although the new pit is fresh in color, its brightness is poor. Old pits and new pits are determined according to the age of jadeite.
5. Land: Emerald land is better, whether it is Philippine or emerald. Some external textures should be fine and even, and some internal textures should be solid, moist, clean and full of water. Good land should be in harmony with the color of emerald, take care of each other, and then set off the beauty of emerald color. The best jade floor is glass floor and egg white floor.
6. Gloss: As a kind of gem, jadeite requires high gloss. It is an intuitive reflection of the quality of jade, which needs a strong glass luster or pearl luster of oil.
7. Handfeel: Due to the high hardness of jadeite, fine and delicate layout, good polishing degree and high finish, it has a very warm and smooth feeling when touched by hand. In addition, it feels cold to put jade on your face or on the back of your hand.
8. Integrity: refers to the integrity of jade, including the connotation of jade without any shortcomings, complete shape and large volume. Regarding the short board of connotation, we should treat it dialectically. Generally speaking, those without black spots, stone flowers and cracks are better than those with these shortcomings, but sometimes weak shortcomings, as long as they are not in the conspicuous part of the product, will not only affect the price of jade, but also prove to be genuine, especially in the market where fakes are everywhere now.
