What does amethyst mean?

Amethyst is a transparent purple gemstone.

It is a variety of quartz whose color can range from pale lilac to a deep purple with red or blue undertones.

Amethyst is considered a semiprecious gem, which is a label assigned to some gemstones that have a lesser value than those considered precious. The darkest varieties of amethyst are usually valued the highest. It is sometimes mistaken for more expensive precious stones, such as purple sapphire.

Amethyst is the birthstone for the month of February. It is associated with the zodiac signs Aquarius and Pisces.

The word amethyst is also sometimes used to refer to a purple color, like that of the stone.

Example: The brilliant purple amethyst really made the necklace stand out.

Where does amethyst come from?

What could a beautiful gemstone possibly have to do with hangover cures and antifreeze?

In terms of composition, amethyst is a type of silica mineral quartz. Its vibrant purple coloring can be attributed to the presence of iron oxide.

But the origin of the word indicates that it was once beloved for very different reasons than its purple color.

Amethyst entered English in the late 1200s from Latin amethystus, in turn from the Greek améthystos. Hazard a guess as to what améthystos literally meant in the ancient tongue of Plato and Aristotle? It meant “not intoxicating, not intoxicated.” (We’re not drunk, we promise!) Greek améthystos joins the prefix a-, meaning “not, without,” and a form of the verb methýein, “to intoxicate.”

Now, in ancient folklore, amethyst was believed to prevent people from getting drunk, and so imbibers wearing the stone could drink without feeling any of the consequences. It is important to note here that what the ancients called amethyst probably wasn’t the quartz variety we refer to today but maybe corundum or sapphire.

This superstition was already known to the ancients. Roman scholar Pliny the Elder even noted the amethyst myth in his encyclopedic Natural History. In one passage, Pliny described how magicians promised amethyst, in addition to its boozy benefits, would both ward off poisons and get face time with kings—if a person carved into it the names of the sun and the moon and wore the gem along with baboon hair and sparrow feathers. There was just something about wine-colored stones, apparently.

Amethyst continues to inspire modern myths, as it were. For instance, the popular animated TV show Steven Universe features a character named Amethyst, a magical sentient alien gemstone whose purple appearance reflects the color of the beautiful mineral. The acclaimed fantasy series, The Broken Earth Trilogy, by N.K. Jemisin features powerful obelisks made from minerals, including amethyst.

If we break down Greek methýein, “to intoxicate,” we can find that this verb is based on the noun methý, meaning, appropriately enough, “wine.” You may be more familiar with methý than you think (and we don’t mean, “it’s always five o’clock somewhere …”). Methý is related to the English word mead, “an alcoholic liquor made by fermenting honey and water”—the stuff those Anglo-Saxons guzzled down in their great halls in Beowulf.

And speaking of the word alcohol, you may have heard of methyl alcohol. This liquid (which you definitely shouldn’t drink) is used as solvent, a fuel, and an automobile antifreeze. Methyl alcohol is also called methanol. Both methyl and methanol derive in part from Greek methý, as do many other related words in chemistry, including methane, methamphetamine, and, lest we forget, hexamethylenetetramine.
