Crystal system groups minerals by the internal atomic pattern their crystals repeat. Wikipedia notes that "quartz exists in two forms, the normal alpha-quartz and the high-temperature beta-quartz, both of which are chiral," each with its own geometric structure. This dimension lets a visitor compare minerals that share the same underlying crystal geometry.
