Adamant
Adamant and similar words are used to refer to any especially hard substance, whether composed of diamond, some other gemstone, or some type of metal. Both adamant and diamond derive from the Greek word αδαμαστος (adamastos), meaning "untameable". Adamantite and adamantium (a metallic name derived from the Neo-Latin ending -ium) are also common variants.

Famous quotes containing the word adamant:
“All things are flowing, even those that seem immovable. The adamant is always passing into smoke. The plants imbibe the materials which they want from the air and the ground. They burn, that is, exhale and decompose their own bodies into the air and earth again. The animal burns, or undergoes the like perpetual consumption. The earth burns, the mountains burn and decompose, slower, but incessantly.”
—Ralph Waldo Emerson (1803–1882)
“In a toddler’s mind, agreeing with you means that he is indistinguishable from you.... The adamant little tot is fighting hard to solidify a personal sense of Self. Selfhood sometimes requires great sacrifice and often precludes cooperation.”
—Lawrence Balter (20th century)
