Interpretation: What is the value of jadeite?
How to identify jade A goods? A: With the warming of the jade market, the means of counterfeiters are becoming more and more sophisticated. It is very difficult to distinguish the advantages and disadvantages of jade products by the naked eye and experience. It is really necessary to identify the technology with the help of technology. Means and advanced technologies such as Charles filter, high magnification magnifying glass, measuring density and thermal conductivity, infrared spectrum Raman test, etc. What is the value of jade? A: As the saying goes, "Gold is valuable for priceless jade", the average consumer is also afraid to buy his favorite jade products because of the lack of knowledge of jade. Some unscrupulous merchants also raise the price of jade, which causes the jade market to be mixed. Mixed with fish and dragons. However, we believe that jade is not only valuable, but her value is still valid. Species (4 levels in total) The species refers to the texture of jadeite, and is also the most basic description of a jadeite product. In the market, the old species, new species, glass species, ice species, egg whites, bean seeds, oil greens, blue Flowers, blue water, clear water, etc. are customary business names, but because these business names do not have a clear definition of standards, they cannot be used as our grading standards. In fact, the size of the crystal particles of jadeite and the relationship between these particles are the main reasons for determining the commercial varieties of jadeite, and the following grading standards have been developed: Level, division criteria The first-order structure is fine and compact, and there are no mineral particles and composite primary cracks under the magnifying glass of 10 times. The particle size is less than 0.1mm. Class 2 structure is dense, 10 times magnifying glass sees mineral particles and few small composite primary cracks, particle size is 0.1~1mm The 3-level structure is not dense enough. Under the magnifying glass of 10 times, the mineral particles and the local fine composite primary cracks are seen. The particle size is 1~3mm. The 4th grade structure is loose, the particle size is very large, and the particle size is above 3mm. Water (5 levels in total) "Water" is an important factor in the evaluation of jadeite. It is commonly known as "water head" in the industry. The high transparency is the water head. This kind of jade is crystal clear and translucent, giving people a feeling of water, and the poor transparency of the jade is dry and dull. With a dry feeling, it is the head difference and the water is insufficient. The transparency of jade can be roughly divided into transparent, transparent, translucent, micro-transparent and opaque. The more transparent the jade, the higher its value: Level transparency, sunny penetration, common commercial varieties Level 1 transparent 10mm or more pure colorless old glass Level 2 is more transparent 6~10mm small amount of old glass grade special grade Grade 3 translucent 3~6mm old glass, ice special grade Grade 4 micro-transparent 1~3mm color thick, coarse grain, new and old species Level 5 opaque sunlight does not enter color, base, new species Bottom (total 4 levels) The bottom refers to the extent of jade flocs (also known as cotton), dark spots, and other stains. Because jadeite is a collection of various minerals, its structure is mostly fibrous structure and granular structure, and the degree of impurities will inevitably affect the value of jadeite. Level division standard 1 grade 10 times magnifying glass does not see any splitting, grayish black silk, occasionally individual white cotton, small black spots in the inconspicuous place 2 grade 10 times magnifying glass, no cracks, see a small amount of fine white cotton, black spots, gray black silk Grade 3 has no cleft palate, a small amount of cleft palate under a magnifying glass of 10 times, a small amount of white cotton, black spots and a small amount of ice residue visible to the naked eye. 4th grade, see a small amount of cleft palate and more white cotton, black spots, gray silk and ice residue Color (6 levels) The common colors of jade are green, white, red, purple, yellow, etc. Among them, green is the best variety. If a jade has both green and red and violet, it is also a very rare jade. . For green jade (such as the ring face), there are traditionally "rich", "positive", "yang", "and". The so-called "concentrate" means green is full and heavy; "positive" means green is pure and contains no variegated color; "positive" means green is bright and bright; "and" means green is even and soft. The color of the jadeite is illuminated under the illumination of a continuous light source with a color temperature of 5000K: Level of purity, uniformity, degree of darkness Level 1 pure green, emerald, emerald green, etc. are extremely uniform and not thick, not faint and bright Level 2 is green, apple green, yellow scorpion green, etc. There are thick bands on the whole, and the plaques and spots are not thick, not bright and bright. Level 3 positive green, apple green, yellow scorpion green, etc. The overall unevenness is not bright and bright. Level 4 slightly blue-green (including bright yellow and violet in yellow and green) is not thick, not light and bright Level 5 blue green is not thick, not light and bright Grade 6 gray-blue (including yellowish green, light red, light violet) evenly and elegantly bright Workers (4 levels in total) In this grading standard, “work†refers to the shape, workmanship, and weight of a jadeite product. It should be pointed out that due to differences in the designer, craftsmanship, cultural connotation, production age, and volume of jadeite products. Each piece has its own characteristics, and detailed grading is impossible. Some websites are so divided: Level shape work weight Level 1 is suitable, full of generous masters, and more than 5 carats Level 2 is suitable, full and generous, natural and smooth, unique and more than 5 carats The 3rd grade is suitable, full and generous, and it is smooth and smooth. Level 4 is suitable for production and generally requires no Cotton Single Jersey Fabric,Stripe Jersey Fabric,Sweater Single Jersey Fabric,Single Jersey Nylon Fabric Shaoxing Chunyi Modern Textile Co.,Ltd , https://www.chunyibd.com
