珠宝质检师谈人养玉,玉养人（Jewelry QC division talk about people keep jade, jade keep people） There is a long tradition of raising jade and keeping jade. Is there any scientific basis for such a statement? First, lets look at the mineral composition of jadeite jade. Jadeite jade is made of mainly contains kosmochlor, chromic jadeit, chromium jadeite, omphacite, albite, aegirine, amphiboles, chromite mineral composition of metamorphic rocks. Generally speaking, the mineral composition of jadeite jade is extremely complicated. But the content of mineral composition of jadeite jade colorless above 90%. Jadeite is a chain of sodium aluminum silicate minerals. Laboratory studies show that jadeite is a low temperature high pressure mineral. The 200-300 degree, 10000 jadeite formed under atmospheric pressure. Jadeite is a mineral that is his color, pure jadeite is colorless. Then where is the color of jade coming from? This is because the jadeite minerals in the Al3+, Cr3+, Na+, Fe2+, there are some isomorphous substitution of Fe3+. This alternative is limited. Otherwise it will destroy the crystal structure of jadeite. Research shows that in emerald green and from Fe2+. Jadeite under normal temperature and pressure is a stable mineral phase. The transformation of mineral phase does not occur at normal temperature and pressure. Secondly, lets look at the structure of the jade. The structure of jadeite jade is quite complex, and there are many kinds of fibers, such as fiber interweave structure and granular change crystal structure. Variable crystalline structure and so on. A well cultivated jade is usually a fibrous interwoven structure and a fine-grained structure. Jade with poor germplasm is usually of medium grain, crystalline structure, or coarse granular crystalline structure. Three the formation and preservation conditions of jadeite jade It is generally believed that jadeite deposit is formed in low temperature and high pressure environment. The formation of jadeite deposit in B
