The SiOSi bond linking two tetrahedra is not straight (180°), but forms an angle of 144° in quartz (). As a result, the overall crystal structure of quartz is quite complex. In other silica modifiions this angle is different, while the angles inside the SiO 4 tetrahedra (defined by the OSiO bond) remain basically the same. The following table lists angles and distances for a few ...

Additionally, Some minerals come in many different colors. Quartz, for example, may be clear, white, gray, brown, yellow, pink, red, or orange. So color can help, but do not rely on color as the determining property. Figure 3 shows one sample of quartz that is colorless and another quartz that is purple. A tiny amount of iron makes the quartz ...
