What element is amethyst made of?

Amethyst is a purple variety of quartz (SiO2) 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.

What element is turquoise?

Turquoise is an opaque, blue-to-green mineral that is a hydrated phosphate of copper and aluminium, with the chemical formula CuAl6(PO4)4(OH)8·4H2O. It is rare and valuable in finer grades and has been prized as a gemstone and ornamental stone for thousands of years owing to its unique hue.

ruby, gemstone composed of transparent red corundum (q.v.), a mineral form of aluminum oxide, Al2O3. Its colour varies from deep cochineal to pale rose red, in some cases with a tinge of purple; the most valued is a pigeon-blood red.

What mineral is used for gems semiprecious?

Emeralds are formed of a mineral called beryl whose chemical formula is a complex mix of beryllium, aluminum, silicon, and oxygen. The color comes from additional traces of chromium and vanadium. Different trace elements can produce other colors, allowing beryl to form semiprecious stones such as aquamarine.

Are all gemstones minerals?

Although most gemstones are considered minerals, some are also non-mineral. Minerals occur naturally in the Earth’s crust and are defined as inorganic substances that have a characteristic chemical composition and crystalline structures. … All minerals can be gemstones, but not all gemstones can be minerals.
