about 6.5 degrees, yellow, brown, brown purple, blue, blue, green, blue and other colors, for the orientation of their densely packed fibers, the appearance like wood structures, with a silk gloss and shiny glass, transparent or slightly opaque. Alexandrite dense fine quality wood can be carved * good, ugg Classic Patent Paisley boots, jade is a mid-range of raw materials, can be used to make jewelry, crafts. Luodian wood alexandrite produced in the body of diabase and sedimentary rocks of the contact metamorphic zone, further explanation is SiO2 alkali solution * amphibole asbestos products. Diabase intrusion in the Lower Permian Maokou and Qixia composed of a siliceous carbonate strata. Luodian wood is wood alexandrite alexandrite cat eye, mostly gray-green, glassy luster, density 2.65g/cm3, refractive index 1.54, mineral composition of quartz, amphibole asbestos, fibrous structure, after processing into the arc-type a cat eye effect. Characteristics of wood alexandrite (Wood alexandrite) is to retain the fibrous structure of asbestos quartz aggregates, because of its color and texture very similar to its name with the trees. Alexandrite is a dense wood arranged in straight fibrous quartz aggregates. Change the color of wood stone often brown, tan, blue and blue-gray, the color is asbestos in the precipitation of iron precipitation in the middle of fibrous quartz particles caused by porosity, fine fiber is very obvious. Change the texture of fine stone wood, with a strong silky luster, burberry watch, opaque. According to the arrangement of color and fiber state is divided into Tiger Eye stone and wood change (tiger eye stone). Tiger Eye stone and wood change (Tiger eye) is actually a kind of “silicified asbestos”, which is the rock fibrous asbestos blue or green veins, the hot aqueous acidic account of asbestos in the precipitation of iron and magnesium, and change become a pure SiO2 aggregates formed. If this becomes a jade silicified asbestos material, the wood becomes known as the broad stone. Wood become stone two main varieties: Tiger Eye and Hawk-eye, which becomes brown wood stone called tiger eye stone, blue wooden eagle-eye alexandrite said. Tiger Eye and Hawk-eye are variants of wood become stone. Tiger Eye is brown, brown wood alexandrite stones after wondering into the arc-type, has the cat eye effect is named.

Wood wood alexandrite cat eye alexandrite Department of asbestos, alkaline amphibole (riebeckite, magnesium riebeckite, arfvedsonite magnesium, manganese amphibole) asbestos product of silicification, silicification also known as asbestos. In the appropriate geological environment (chemical, physical), Si02 colloid solution constantly, gradually crystallized, account of asbestos (serpentine type of asbestos), blue asbestos (blue asbestos is the trade name alkaline amphibole asbestos) the formation of silicide asbestos, wedding dresses with sleeves, silicified serpentine, jade alkaline amphibole asbestos reach targets when also known as wood become stone. Wood alexandrite with his main form of granular aggregates of quartz, granite tablets with changes ranging from crystal structure, because metasomatism strength of different retained in quartz aggregates under the serpentine, the fibrous structure of alkali amphibole and residual crystal, when the fibers are arranged parallel to ring when you can figure out the curved surface generated cat eye effect, when the distribution of fiber when you can make the best use messy to figure out other crafts Identification of Tiger Eye stone and wood identification variable. Tiger Eye stone and wood become a special color, brown yellow, blue brown, there is a clear and bright fine structure of silk fiber luster, which is the nature of jade does not have any. Tiger Eye stone and wood the color change more deeply, to make it more beautiful, more than before in the production of finished billets soaked for half an hour into the oxalic acid, dissolve a portion of iron, so that the color lighter. It should be noted, however, do not wear a good product into hydrochloric acid, otherwise it will affect the gloss intensity. Evaluation and purchase of wood become stone Tiger Eye is a mid-range jade material, generally used as necklaces and jade carving material. The basis for evaluation and purchase: the texture is delicate, elegant colors and block size. Yellow, red, blue, fine texture, no voids, no impurities, weighing 10 kg or more for a product. Wood and stone tiger eye stone becomes the difference between wood alexandrite (Wood alexandrite) is to retain the fibrous structure of asbestos quartz aggregates, because of its color and texture very similar to its name with the trees. According to the arrangement of color and fiber state is divided into wood and tiger eye stone alexandrite. Tiger eye stone and wood become stone (Tiger eye) is actually a kind of “silicified asbestos”, which is the rock fibrous asbestos blue or green veins, the hot aqueous acidic account of asbestos in the precipitation of iron and magnesium, and change become a pure SiO2 aggregates formed. If this becomes a jade silicified asbestos material, paul smith shop, then called the broad wooden alexandrite. Wood become stone two main varieties: tiger eye stone and eagle eye stone, ugg Ultra Short Boots, in which brown stone called Tiger wood becomes clear stones, blue wooden eagle-eye alexandrite said. Precisely, wood and tiger eye stone alexandrite (Hawk-eye) are retained asbestos fiber structure of quartz aggregates. Tiger eye stone and wood become stone identification.

Wood become stone, produced in Qiannan Buyi and Miao Autonomous Prefecture of Guizhou Province Luodian, Bijie Zhijin County and other places. The stone to dense and tough, the hardness of wood become stone
SiO2 formed aggregates of cryptocrystalline quartz, but it retains the fibrous structure of asbestos, because of their appearance like wood and is known as “wood alexandrite. ” Crocidolite hardness of 5, a density of 3.02 ~ 3.42g/cm3. After the account is SiO2, wood changed into stone, the hardness increased to 7, the density decreased to 2.64 ~ 2.71g/cm3, explanation is not complete, its hardness and density values ??in between. Become common as wood stone brown, brown and red brown, blue and gray-blue is also more common, in addition to visible gold, purple and variegated brown and so on. Fine texture tough, micro-fibrous structure is very obvious, with a strong silky luster, cat eye effect is remarkable. These features are not available other jade products, and thus easily distinguished from other types of jade.
