Level division of jade knowledge "species"
The name of the "species" of jade in the market today is really letting people fall into the fog of the clouds and can't touch them. What kind of glass, ice, golden silk, Guanyin, peas, hibiscus, horses, thunder, etc., I’m dizzy, I don’t know what to see. In which category of things to go. What's more, there is a saying that it is better to buy a kind of colorless ones and don't buy colored ones. I would like to ask you to buy an old pit glass of colorless jade jewelry worn on your body, you said it is boring! ? I know that you bought a piece of jade without color, I don’t know if you think this stuff is a piece of glass! In addition, when I came across a very green color, the jade of poor texture, the green stuffy inside did not come out and was commonly called "sad suffocation". I don't think everyone would consider buying it, because it looks like a piece. Green stone, not like a piece of jade. So, in this case, the species and the color and the water are to be combined. It is not a scientific analysis problem. The first thing to do is to figure out what is "species"! In fact, the so-called "species" is to say the texture of jade. Anyway, my consciousness has always been to classify the texture of jade according to the old name. When I hear the fresh title, I need to listen to the English, first translate the name. understanding. 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 standard 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. SUSAN GIFTS CO.,LIMITED , https://www.susangifts.com
