Amethyst is the purple variety of the quartz mineral species. It’s the gem that’s most commonly associated with the colour purple, even though there are other purple gems such as sapphire and tanzanite. Its purple colour can be cool and bluish, or a reddish purple that’s sometimes referred to as “raspberry”.

Amethyst’s purple colour can range from a light lilac to a deep, intense royal purple, and from brownish to vivid. Amethyst also commonly shows what is called colour zoning, which, in the case of amethyst, usually consists of angular zones of darker to lighter colour.
