Throughout the ages, amethyst has been coined the true essence of the colour purple, which is often associated with ideas of royalty, luxury and power.
Amethyst colours range from light to dark purple; the transparent deep purple colours are the most highly regarded. The hue of the Amethyst depends on its mining origin – in some parts of the world where amethyst is found, for example Uruguay and Arizona (USA), amethyst has a deep purplish tone with strong hints of blue. In other locations, like Russia, the typical purple amethyst has more of a reddish hue as well as subtle blue aspects.
Amethyst holds the potential to change colour when it is heated, either naturally or in a lab. Prasiolite is the name given to amethyst which turns green when reacting to heat. Citrine is another variety of amethyst produced by heat and is golden yellow in colour.
Amethyst is the birthstone for February and the gemstone for the 6th and 17th wedding anniversaries.
