Amethyst
amethystos — “not drunken”
The Greeks drank from amethyst cups, trusting the stone to keep the head sober while the wine did its work — amethystos, “not drunken.” For most of history it ranked beside ruby and emerald, the purple of bishops and empresses, until Brazil’s great finds handed it to everyone. The color is iron and natural radiation, worked over geological time.
