However, the imitation of jade in the market is also endless, especially those who do not know jade identification, often easy to be deceived. So today, the small series of China Jewelry Merchants Network will give you a brief introduction to the jade identification method. Let's go and have a look!
Emerald
colour
The color grade of jade, we must distinguish the color when judging jade. Jadeite is mainly red, green and purple. The green color in the monochromatic jade, the elegant purple and red color are the high-end products in the jade, and the green is the most precious.
layout
The jadeite is mostly staggered, mainly referring to the layout of the fine fibrous mineral crystals around the granular phenocrysts under the action of transmutation. In most jadeites, there are small clump-like white flowers composed of unclear or microscopically clear white fibrous crystals, which are called "stone flowers" or "stone brains".
Water head
Refers to the degree of transparency. The higher the water head, the better the jade. Emerald clearness is related to itself, we must be very careful when we identify. In addition, it is necessary to pay special attention to the jade center is the kind of hollowing out, because the agate's transparency is also good, so some businesses will use agate to counterfeit jade.
Seed pit
The pits of jadeite are composed of layout and texture, while jadeite is composed of small crystals. The smaller the crystal grains, the finer the texture and the better the transparency. The jewellery industry often divides the pits into old pits and new pits. The old pits are bright in color, and the color and the ground are integrated into one. The transparency is high and the quality is the best. Although the color of the new pit is also fresh, the transparency is poor. The old pit and the new pit are determined according to the age of the emerald.
Ground
Authentic jade land is better, whether it is ç¿¡ or ç¿ , some texture is fine and even, inside is a solid texture, fine, clean, water head, and good land must be coordinated with the emerald green color, mutual care, Then set off the beautiful green jade. Emerald land is usually best for glass and egg white.
luster
Jade has a high requirement for gloss, and it can directly reflect its good or bad. After the jade is soaked with strong acid and alkali, the structure becomes loose, causing diffuse reflection and weakening of the gloss. After adding organic fillers such as resin or plastic, jade often has a resin, waxy luster or glass luster mixed with resin and waxy luster.
Feel
The jadeite has a relatively high hardness, a fine layout, excellent polishing, and an excellent feel. It will be very warm when touched by hand. In addition, the authentic jade will stick to the face and it will have a cool feeling. This jade will not heat up with body temperature.
Full
Multi-finger jade is full of perfection, without any shortcomings, the shape is perfect and the block is large. The connotation and shortcomings of jadeite should be viewed dialectically. On the whole, it does not contain black spots, stone flowers and clefts, but sometimes it does not have some small defects in the conspicuous parts of the product. It will not only affect the value of jadeite, but can prove that it is real. Especially in the modern market full of counterfeit goods everywhere.
