What is an amethyst's chemical composition?
Mainly SiO2 with traces of Fe and Al to give it its purple colour.
How does amethysts form?
Silicon dioxide (SiO2) is the chemical composition of amethyst. It is a mineral which is formed like anyother mineral under the earths crust due to heat and pressure.
Is amethyst fluorescent?
Fluorescence is a term that is used to describe a gems' (especially a rubies) capabilities to glow on its own. In fact, the stone is reflects ultraviolet light. Amethyst is a variety of quartz which does not normally exhibit fluorescence.
When water evaporates its chemical composition?
The chemical composition remain unchanged.
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.
Is a amethyst metallic?
No, amethyst is not metallic; it is a variety of quartz that is known for its purple color. Its composition is primarily silicon dioxide (SiO2), and it exhibits a glassy luster rather than a metallic one. Amethyst is valued for its beauty and is often used in jewelry and decorative items.
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.

Are rocks a chemical makeup?
Yes, the composition of the rocks is as a result of the distinct chemical composition.
How is amethyst formed by nature?
Amethyst crystals are actually quartz (SiO2) crystals with a purplish hue derived from impurities of iron and aluminum. The crystalline structure forms from the latticework arrangement of silicon and oxygen atoms unique to quartz. Quartz crystals like amethyst can develop from silica saturated solutions or even from molten silica solutions.
Does melting ice changes the chemical composition of water?
The chemical composition of water remain unchanged.
