Study On Gemmological And Petrological Characteristics Of Colorless Series Of Albite Jade

China is jade country, China jade culture broad and profound, in Chinese culturalhistory, jade culture occupies a very important position, especiallyunder the influenceof Confucianism, the sages, the characteristics of men of literature and writing on thejade itself has to be moral analogy and extension, make its and character combinationup. A gentleman without reason, jade go; I think the gentleman, Wen Ruyu. In thefeudal society,jade is a symbol of the wearer’s social status, the different rank, TitleRankstrictly according to certain standard with its status.Along with the people to the jade mining and deepening understanding,jade,Hetian jade and jade have occupied the mainstream society at that time the king ofjade or jade position. Today, jade has already walked intothousands of households,from God jade, jade jade officer developmentpeople, people love or collection of jadeis not limited to a single jade, jade market increasingly diversified development.The jade market, jadeite jade quality, the price certainly occupies the highestpoint, but with the further depletion of jade resources and irrationalprice increases,people have started to pay attention to similar jadevarieties or alternative varieties ofjade. These jade varieties or in theoutput and the emerald has have all kinds ofconnections with relationship,or in appearance and jade indistinguishable. The albitejade as a substitute for the most successful, no matter in production or in the physicalproperties, chemical composition and appearance features and jade has not a smallrelationship.The albite jade first appeared in the Yunnan Ruili jewelry market, commonlyknown as "water mist". This paper focuses on the research of the albite jadein thecolorless variety series. Brief introduction of the albite jade basic properties, includingmaterial properties, the albite jade occurrence and classification, and put forwarddifferent schemes of classification to the albite jade. The physical property ofcolorless series of albite jade, test thecolorless series of albite jade samples usingconventional gemmologicalinstruments, including optical and mechanical propertiesetc.. The sodiumfeldspar framework silicate structure and its forming temperatureenvironment limits the isomorphism occurs, resulting in the albite jade colorseries monotonous. The colorless series of albite jade mineral composition and structure,analysis of the albite jade from the view of petrology, the samples were observed bypolarized light microscope slices, structurepreliminary master colorless series of albitejade mineral composition information and judge the colorless series Na Chang Shiyu,and illustrates the influence of albite jade mineral composition and structure the albitejadequality. The colorless series of albite jade in "gone with the wind to determine theflower" minerals, except that amphibole mineral, andpyroxene group mineralsparticipation; albite jade in the white translucent or opaque spots and pyroxene; notfound in a fibrillar structure in the colorlessseries of albite, explain the reasons of itshigh transparency is mainly caused by mylonitic structure, also does not have thefibrous structure issodium Chang Shiyu bracelet jade bracelets on a main muffled.Chemical composition by electron probe of colorless series of albite jade sampletesting and analysis of the data obtained quantitatively minor minerals albite jade in,and to determine the mineral species. Which caused "gone with the wind flower" ofpyroxene diopside, including Lv Huishi and jadeite. When the content of Cr2O3injadeite is not enough to reach the green jadeite, there was patchy white opaque ortranslucent in albite jade, which constitute the albite jade in the "foam". In thedifferential diagnosis of albite jade andsimilar jade, jadeite identification mainlyintroduces, quartz and albite jadejade, gemmological and differential methodsincluding infrared spectroscopyroutine test, and combined with the quartz jade"structure of mineral composition and structure of Ying" samples of the albite jade"jade like stone" mechanism, the jade "scattering Ying" phenomena and light, andrefraction rate, jade itself color, transparency, cut and mineral compositionof structure.Finally, discusses the naming and quality evaluation of the albite jade hand, whereinthe albite jade named combined with similaritychanges on the definition and jadeitealbite jade and jadeite output in therelationship and the appearance of the nationalstandard, it should be classified as a member of the emerald family, and named asalbite qualityjade, corresponding to the jadeite jade, jadeite omphacitic jade, sodiumchromium omphacitic jade and jadeite minerals sodium feldspar in accordance withdifferent. As for the evaluation of colorless series of albitejade is briefly presentedfrom transparency, clarity, variegated ("floating flower" and "foam" part) to evaluateseveral aspects of morphology.
