The name Diamond is an English word name derived from the precious gemstone of the same name. The word diamond comes from the ancient Greek word "adamas," which means "invincible" or "unbreakable." This likely refers to the hardness and durability of the diamond gemstone.

As a given name, Diamond is a relatively modern coinage, with its earliest usage dating back to the late 19th century. One of the earliest recorded individuals with the first name Diamond was Diamond Bessie Moore, an American criminal and saloon owner who lived from 1873 to 1959.

Another notable historical figure with the name Diamond was Diamond Jim Brady, an American businessman and jeweler known for his lavish lifestyle and love of diamonds. He lived from 1856 to 1917 and was famous for wearing extravagant diamond-studded jewelry.

In the 20th century, the name Diamond gained popularity as a unisex name, particularly among African American communities. One famous bearer of the name was Diamond Lil, a stage name used by American actress Mae West, who lived from 1893 to 1980.

Another notable Diamond was Diamond Teeth Mary, the nickname of Mary Smith, an African American woman who lived from 1904 to 1994 and was known for her diamond-studded teeth.

In more recent times, the name Diamond has been given to several high-profile individuals, including Diamond Dallas Page, an American professional wrestler and actor born in 1956, and Diamond Brown, an American singer and actress born in 1981.

While the name Diamond is not directly referenced in ancient texts or religious scriptures, its association with the precious gemstone and its connotations of strength, durability, and value have contributed to its appeal as a given name.
