What you find when scratch a mineral over an unglazed tile?
What you are referring to is called a streak test. It's used as an aid to mineral identification. As a mineral is drawn over the unglazed tile surface, it is reduced to a streak of dust which reveals the true color of the mineral. If no color is revealed, the streak color is called white. An amethyst crystal which appears purplish will actually have a white streak, because the streak color of the constituent quartz is white. The purplish color of amethyst is due to other reasons.

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.
