| About the name | From Greek "a-methystos", meaning "not drunk". In ancient times, it was believed that amethyst warded off drunkenness. Drinking cups were sometimes carved from amethyst. At the same time, the colour of the red wine drunk from these cups is said to have been approximately the same colour as the cups. Therefore, the wine could be diluted with water without the drinker noticing, thinking it was the material of the cup itself that warded off drunkenness. |
