【摘要】 翡翠的质量主要取决于它的颜色和结构，就颜色而言，主要取决于其中的矿物组成和化学成分。翡翠主要由辉石族矿物、闪石族矿物、长石族矿物等组成。其中辉石族的矿物如硬玉、霓石、钠铬辉石、钙铁辉石，它们的存在和数量的多少及化学成分的变化对翡翠的质量影响很大。另外，闪石族矿物使翡翠的颜色偏暗，部分飘蓝花，直接影响翡翠的质量。更多还原

【Abstract】 The quality of jadeite is decided by its color and texture. Its color depends on its mineral and chemical composition. Jadeite is made up of pyroxene, amphibole and feldspar group minerals, in which the existence,quantity and change of chemical composition of pyroxene group minerals, such as jadeite， aegirine,vryite and hedenbergite, largely influence the quality of jadeite. Besides these, amphibole group minerals can make jadeite a little more darker， influence the quality of jadeite.更多还原
