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.
What is the specific gravity of magnetite?
There is no such thing as a specific gravity for any element.
How does specific gravity effect head pressure?
Head pressure=specific gravity*1000*gravity*height. Therefore if specific gravity is increased head pressure will increase.
What fluid has the biggest specific gravity?
Oil has the highest specific gravity. Water has the second.

Is Lt amethyst a kind of pearl?
Light amethyst is a color. A pearl can be that color, but it is not a specific kind of pearl.
