Granitic pegmatite vein intruded into biotite-gneisis along gentle inclined joint. Divided 3-5 texturezones in the vein. Water-bubble aquamarine occurs in geodes of massive microcline and amethyst in geodes ofmassive smoky guartz or massive microcline. The geodes has a diameter from least 1cm to 80cm. All amethystcrystals are parall intergrowth. The parall intergrowth is diffrent with 3 types (coneretion shape
crystal balland comb shape )that Holden has pointed. This paper points out that 3 types of mineral coexisting in a vein aremineralogy mark of aguamarine and amethyst. They are strong greasy luster smoky guartz
green wedge muscovite great crystaline and beryl minerals. These not only raise using Value of ore diposit oneself
but also unfold a huge prospect that is rich in natural gem resources in Altai.
