The article discusses a study on the refractive indices of quartz crystal under different light wavelengths. The study used the interferometrical measurement of refractive index on test crystals from the Maramures area exposed to three different wavelengths to calculate Cauchy coefficients with the ...
Crystal Quartz Since approximately 1970 most crystal quartz components have been produced from man-made cultured quartz, which has the same physical, optical and electronic properties as natural quartz. Cultured quartz stones exhibit all the faceting of natural quartz except that the longest dimension ...

manufacturer cultured quartz crystal are free of electrical and optical twinning, cracks, fractures and other gross imperfections in the useful volume of the crystal. The presence of such imperfections is detected by visual examination of a representative sampling of bars using a refractive index matchi...
elongated crystals that normally only have one terminating end. Diamonds form eight-sided crystals with approximately equal lengths and widths. Differences in density, refractive index, hardness and cleavage also differentiate quartz from diamond, although hardness and cleavage tests require damaging or des...
reflecting roughly equal bond strengths throughout the crystal structure. Breakage in such minerals is known asfracture. The termconchoidalis used to describe fracture with smooth, curved surfaces that resemble the interior of aseashell; it is commonly observed in quartz andglass.Splintery fracture is...
