The difference between quartz Shi Yu and jadeite jade
Quartz jade and jadeite jade can be distinguished from four aspects: surface characteristics, structure, density and absorption spectrum.
Quartz stone is a kind of short board which is produced by the stone plate manufacturers at present. Because of the main content of quartz is more than 93%, it is called quartz stone.Quartz is a kind of physical and chemical properties of mineral resources are very stable, clear quartz stone use imported quartz particles as raw materials.The oxide mineral composition of silicon is SiO2. Mainly refers to the widely distributed three party system of low temperature quartz (alpha quartz). When the temperature is above 573 degrees Celsius, it becomes the high temperature quartz (beta quartz) of the six square system. A low temperature quartz crystal often having six pointed columns with pointed ends. There is a transverse line on the cylinder, and there is a difference between the left and the right. Twinning is common, the most common for the Dauphine twin and Brazil twins. Usually crystalline or granular or massive aggregates. Pure is colorless and transparent, but mostly because of containing trace pigment ions or subdivision of loose color wrapped, or because of the color center and various colors, and reduce transparency. Vitreous luster, fracture often oily luster. Mohs hardness 7, specific gravity 2.65. Shell fracture. With piezoelectricity and optical rotation.
Polished jade surface with orange peel effect, and quartz jade; jade is fiber weaving structure, the structure of granular quartz jade; jade density is 3.33, quartz jade jade density 2.65; absorption spectra of 437 absorption lines, quartz jade no 437 absorption lines.
