Color

Amethyst is given its purple color from impurities of iron or manganese. The color amethyst refers to the color of the mineral. Amethyst is sometimes heated to deepen its color, or turn into Citrine.

Streak

The streak of Amethyst is white, along with quartz and all of its derivatives.

Crystal Form

The crystals are usually striated horizontally. They're also of hexagonal formation.

Cleavage/Fracture

Where Amethyst is Located and Mined

It's commonly found in Canada in Ontario and Nova Scotia. The largest Amethyst mine in North America is in Ontario.


Bulldozers and excavators are used to strip, excavate and expose the amethyst veins. The veins are then mined selectively by pick and shovel. The lower grade amethyst is stockpiled to provide bulk feed for the washing plant.
