Amethyst is a high-quality form of quartz crystal, naturally found as clusters in a nodular stone. They are found sometimes in volcanic vugs or small cavities in rocks. The chemical name for Amethyst is Silicon Dioxide. Amethyst obtains its color through a combination of manganese impurities and iron.
The purple color comes from the presence of manganese, while the existence of iron in certain quantities controls the intensity of the color. Artificial heating treatments have been used on Amethyst to produce popular gems known as Citrine and Ametrine (400 and 500 degrees Celsius). Amethyst measures 7 on Mohs' hardness scale.
One of the largest cut amethysts in the world is 343 carats and is being displayed at the National History Museum in London. Very dark stones are sometimes heated to enhance color.
