What does peridot mean?

Peridot (pronounced PAIR-i-doh or PAIR-i-dot) is a transparent gemstone that ranges in color from light green to bright green to dark green.

Peridot is a variety of the mineral olivine and is sometimes called precious olivine. It’s considered a semiprecious gem, which is a label applied to a class of gems that have a commercial value that’s less than that of stones labeled precious, such as diamonds.

Peridot is one of the birthstones for the month of August. It is associated with the zodiac signs Leo and Virgo.

Example: Since I was born in August, I sometimes get peridot jewelry as a birthday gift.

Where does peridot come from?

The first records of the word peridot come from the 1300s. It comes from the Latin pæderot-. It may also come from the Arabic faridat, which means “gem.”

Peridot is a variety of olivine, a magnesium-rich, rock-forming mineral that occurs in Earth’s upper mantel and in metamorphic rock. Olivine is named for its green coloring (like an olive), which can naturally vary from a yellow-tinted green to deep green. Peridot was prized by the ancient Egyptians.
