Well it's kinda easy 'cos there are hardly any rocks that are purple other than amethyst. Firstly amethyst is violet, secondly it's usually transparent and sometimes has white parts, and lastly amethyst occurs in a hexagonal prism naturally. Oh, and you wouldn't find a polished amethyst crystal on the ground, trust me.

The value of a purple crystal rock, such as amethyst or another type of purple gemstone, can vary significantly based on factors like size, quality, and clarity. A large, high-quality amethyst may be worth anywhere from $20 to $100 per carat, or even more for exceptional specimens.

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.
