Amethyst is the name for the purple variety of quartz.

Nineteen48 amethyst is responsibly sourced from artisanal miners in Sri Lanka and Tanzania.

Quite often, large pieces of rough material is found which allows more innovative cuts in large sizes.

Nineteen48 amethyst is not treated in any way to affect the colour or clarity.
