About Pseudocubic QuartzHide

Formula:
SiO2
A variety of Quartz

Crystals with a (pseudo)cubic appearance that are dominated by a single rhombohedral form (usually r, { 1 0 -1 1 }). Since the angles of the rhombohedron differ only very little from that of a perfect cube (85.2° and 94.8°, respectively, instead of 90°), the crystals look like a slightly skewed cube.
