Amethyst is actually a purple variety of quartz and its colour is caused by iron (Fe4+) impurities in the 10s to 100s parts per million range. If this violet gem stone is heated, amethyst turns yellow-orange, yellow-brown, or dark brownish, and thus resembles the quartz variety citrine. Amethyst has also historical and cultural significance as in the ancient Egypt it was largely employed in antiquities. The Greeks believed amethyst gems could prevent intoxication, while medieval European soldiers wore amethyst amulets as protection in battle in the belief that amethysts heal people and keep them cool-headed.

Anyone wishing to protect a drunkard from delirium mixed some pulverized amethyst into the person’s drink.
