♒︎ The lucky stone of Aquarius: amethyst
Colour: violet. Also named: aquamarine, rock crystal.
The amethyst is violet, and this colour of the unusual suits Aquarius. Its name means 'not drunk' in Greek, and tradition gives it a clear mind.
The lucky star of Aquarius in the real sky: Sadalsuud.
The assignment of stones is tradition, and the lists differ. It is not medicine.
