MORE ABOUT DIAMOND
What does diamond mean?
A diamond is a clear gemstone known for its use in jewelry and its high price.
The word diamond can also refer to the material, which is one of the hardest known substances. It has many practical and industrial applications, including for grinding and polishing—many drill bits have diamond tips, for example.
Diamonds are perhaps the most popular gemstone used in jewelry. They are classified as precious gems, meaning that they have a high commercial value. They are often rated based on four main qualities: cut, color, clarity, and carat weight. Many cut diamonds are crystal clear, but sometimes they come in other transparent colors, including pink, yellow, and blue (like the famous Hope diamond). Some diamonds are synthetic—they’re manufactured in laboratories.
The word diamond is also used to refer to a shape (♦), like the one that’s used as one of the four “suits” on playing cards. Sometimes, it refers to a shape that looks like a cut diamond gem. This is how the word is used in baseball diamond.
Diamond can be used as an adjective to describe things that include diamonds (as in a diamond necklace), are made of diamond (as in a diamond drill bit tip), or are diamond-shaped or diamond-patterned, among other things.
The word diamond is sometimes used to describe a 75-year anniversary, as in It’s my grandparents’ diamond anniversary this year—I can’t believe they’ve been married for 75 years!
Example: Look at her ring—that must be the biggest diamond I’ve ever seen!
Where does diamond come from?
Etymologically speaking, the word diamond comes from the Latin adamas, meaning “hard metal” or “diamond.” It ultimately comes from Greek work that perhaps meant “unconquerable”—a reference to its famed hardness—from the prefix a-, meaning “not,” and damân, meaning “to tame” or “conquer.” The first records of the word diamond come from the late 1200s.
Naturally speaking, diamond is the purest form of carbon. Diamonds are formed under conditions of extreme temperature and pressure. They are most commonly found in volcanic rock. Only a small percentage of diamonds are suitable for cutting into gemstones. Poorly formed ones are used in abrasives and in industrial cutting tools.
The modern popularity of diamonds is often traced in part to a 1950s marketing campaign to associate them with engagement rings. Despite diamonds’ popularity, price, and reputation for rareness, many other precious gems are just as rare or even rarer.

How is diamond used in real life?
Due to their popularity in expensive jewelry, diamonds are associated with wealth and luxury. However, because diamond mining has a history that’s associated with exploitation of workers in war-torn areas, some people avoid diamonds or only purchase ones that are classified as “conflict-free.”
