Usage

What does emerald mean? An emerald is a rare, transparent, deep-green gemstone. Emeralds are a rare green variety of the mineral beryl. They are classified as precious gems, meaning that they have a high commercial value. Emeralds can be very expensive. The value of emeralds is often based on how dark they are, with darker ones being priced higher. The emerald is the traditional birthstone for the month of May. It’s associated with the zodiac signs Taurus and Cancer. The word emerald can also be used to refer to a deep color of green, sometimes called emerald green, or to describe things that are this color. Example: My grandmother gave me this emerald ring to remember where our family immigrated came from—Ireland, the “Emerald Isle.”

Etymology

Origin of emerald

First recorded in 1250–1300; Middle English emeraude, emeralde, from Anglo-French, Old French esmeraude, esmeralde, esmeragde, from Latin smaragdus, from Greek smáragdos; probably ultimately from Semitic b-r-q “to shine,” also the ultimate source of Sanskrit marakata “emerald”

Explanation

Emerald is a green gemstone. It's also the name of this particular shade of green. On St. Patrick's Day, you'll see the color emerald everywhere — in cupcake icing and maybe even in your beer. Green things are called emerald because of the emerald itself, which is a green, transparent form of beryl and a precious gemstone. Gemstones are found in many forms of jewelry, and they're especially loved in Ireland, which is also known as the Emerald Isle. Like many gemstone names, emerald has a long pedigree in many languages: most immediately French, Latin, and Greek.
