2. The "species" of jadeite are roughly divided according to the transparency, particle size and crystal structure of jadeite. Common species are: glass seed, ice seed, wax seed, bean seed, etc.
Emerald has various colors, among which green is the most expensive. When evaluating the color value of jadeite, we should keep in mind four words, namely "strong, positive, positive and harmonious" or "strong, positive, positive and uniform". "Thick" means that the color of jadeite should be rich and colorful, so that its value will be high. It also requires that the color should be correct, that is, the color is pure, the tone is not biased, and there is no noise, which is the so-called "evil" in jargon. Yang means bright colors, showing bright colors in natural light, neither dark nor low. Harmony means that the colors should be evenly distributed, full and harmonious.
4. In terms of color quality, the best colors of jadeite are: royal green (emerald), emerald green, apple green and sun green. Followed by cyan, purple, scarlet, yellow, blue, gray-blue, black and so on. It is rare to combine two or three colors (purple green, yellow purple green, etc.). ), that is, the so-called spring scenery and colorful jade, but such a color must be combined with the seed water of jade, and the impurities are less to be cracked into priceless treasures.
5. It is difficult to identify the color change of jadeite water with 36 water, 72 beans and 108 blue. It is not to divide the 36-water 72-bean 108 blue of jadeite one by one for our identification.
6. If you want to have a beautiful jade jewelry, you must be very careful from the beginning of material selection. After selecting a piece of jade, it is necessary to "cut the material", that is, cut the jade into the appropriate size according to the preliminary design. Then peel off the impurities on the surface to reveal the true colors of jade. Because jade production pays special attention to cutting and tailoring, sculptors often add patterns while carving. After the jade is carved and shaped, it must be polished many times to show the luster and color of the jade itself.
7. Pay attention to three conditions when purchasing:
(1) Choose real jade, not fake jade.
(2) It is this jade. What do you think of its carving theme? Because most jadeites pray for others, you choose a jade ornament to pray for yourself, your relatives and friends, and your family, so this theme is very important.
(3) Style design is also very important. Choose jade ornaments that suit your style and reflect your temperament.
8. The most effective way to identify the authenticity of jade jewelry is to let the seller issue an identification certificate from a national accreditation body. Because only natural A-goods will issue a certificate with the result of "Jade", and if it is B-goods jade, the identification result of the certificate will be marked with "Jade (treatment)" or "Jade (glue injection)" or "Jade (B-goods)" or "Jade (optimization)". The jadeite of C goods will be marked with "jadeite (dyed)", while the jadeite of D goods will not appear in the results of the appraisal certificate. If it is a substitute, the name of the substitute will be marked, such as "artificial glass", "dyed quartzite", "Xiuyu" and "Ma Laiyu".
