What atom is Amethyst?
It is composed of the elements silicon and oxygen and in its pure state is colorless. Small amounts of various impurity atoms can produce a range of colors in quartz. Amethyst, the most valuable gem variety of quartz, is purple. Just a few atoms of iron replacing some of the silicon will cause the purple color.
Is Amethyst a rock?
Amethyst is actually classified as a mineral. Most rocks are made of minerals. Amethyst can be found in igneous and metamorphic rock and sometimes even in sedimentary rock. Amethyst is made up of mainly quartz, a silicon ore, which is a naturally occurring inorganic solid with a crystalline structure.
What is amethyst fluorite?
Purple Fluorite forms cubic crystals and has a vitreous luster. Amethyst has conchoidal fracture faces and hexagonal crystal shape. Basically, Fluorite has a lot of right angles, and Amethyst forms hexagonal points (similar to Clear Quartz). Another thing you can do is place your raw specimen in the light.

Amethyst is a variety of quartz and its chemical makeup is composed of silicon dioxide. Quartz is formed in lava, specifically when gas bubbles become trapped, allowing crystals to form inside the cavities created by the bubbles.

Amethyst is a purple variety of quartz (SiO 2) and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions. The hardness of the mineral is the same as quartz, thus making it suitable for use in jewelry.
