The crystal chemical composition and nature :

The chemical formula SiO2. Pure colorless transparent quartz crystal is a variant. Chemical composition containing Si-46.7%, O-53.3%. Because of the mixed with different objects or machinery which was mixed with a variety of colors. Purple and green iron (Fe2 +) ion induced color, purple also be titanium (Ti4 +) - induced, other colors from the color color caused by heart. The crystal contains sandy, debris-goethite, and hematite, rutile, magnetite, garnet and chlorite such inclusions; the crystal was found visible to the naked eye like hair-like needle-like mineral inclusions formed. Iron and manganese were said Damien; Iron (golden yellow or colored) yellow crystal; manganese and titanium was claimed in rose quartz Rosa; color claimed tobacco smoke crystal; brown claimed Chajing; black who called MO Jing-transparent; The green color were called Stone pulp.

Crystal crystal structure and morphology :

An trigonal system. Crystal Prism was to bring hexagon-cone, cylinder with stripes and Damien were often Horn ribbon. In nature, crystal appearing DRUSE output and the shape of beauty.

Crystal of the physical nature :

Crystal was colorless, purple, yellow, green and tobacco color, luster glass, transparent to translucent, hardness 7, sexual crisp, the proportion of 2.65, no cleavage, melt fracture, but also a good equal ridge chevron fracture. Damien is a clear two colors, yellow crystal and weak tea with the crystal Dichroism. Luminescence crystal with a strong sexual phosphorescence. Placer gold with green crystal in a long, a short-wave ultraviolet radiation under a gray green fluorescence. With Cat, iridovirus and gold effects. With piezoelectric crystal.
