What is the crystal shape of the gem Amethyst?
Amethyst is a form of quartz. Quartz belongs to the trigonal crystal system. The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end.
How are smoky quartz and rose quartz alike?
Amethyst is a variety of quartz. It has a composition [chemical make-up] of SiO2 [silicon dioxide], as all varieties of quartz do. Pure Quartz with no inclusions or pigmentation [coloring] is called rock crystal. But amethyst is principally colored by traces of iron.Amethyst belongs to the geological group named silicates-tectosilicates and has a trigonal or hexagonal crystal system. The color of amethyst is purple, and it bears a hardness of 7 on the moh's scale of hardness.When streaked, amethyst appears white, and it bears a conchoidal fracture. Amethyst is 2.7 times heavier than water [has a specific gravity of 2.7] and can be turned into citrine with heat treatment.So in summary, the composition, geological group, hardness, streak and specific gravity is the same as all quartz are. After all, amethyst is a variety of Quartz.
