Geological Facts

Also known as Dogtooth Amethyst due to its sharp 'teeth' like banding. It is one of the strongest versions of Amethyst because it combines the properties of quartz and amethyst in a dense, striped pattern.

Field Identification & Locations

Identify by the distinct white and purple 'V' shaped bands. Commonly found in Brazil, Zambia, and India. Collectors should look for high contrast between the deep purple and bright white layers.
