Orthorhombic

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.

Aragonite, Materials

Entity-backed identity for the material classification this material already carries as an enum fact, pointing at the class subcategory of the same name. The enum fact itself stays on the entity unchanged.
