Webster's 1828 Dictionary

DIAMOND, n. Dimond. [L., Gr. See Adamant.]
1. A mineral, gem or precious stone, of the most valuable kind, remarkable for its hardness, as it scratches all other minerals. When pure, the diamond is usually clear and transparent, but it is sometimes colored. In its rough state, it is commonly in the form of a roundish pebble, or of octahedral crystals. It consists of carbon, and when heated to 14 degrees Wedgewood, and exposed to a current of air, it is gradually, but completely combustible. When pure and transparent, it is said to be of the first water.
2. A very small printing letter.
3. A figure, otherwise called a rhombus.
DIAMOND, a. Resembling a diamond, as a diamond color; or consisting of diamonds, as a diamond chain.

Diamond Di"a*mond (?; 277), n. [OE. diamaund, diamaunt, F. diamant, corrupted, fr. L. adamas, the hardest iron, steel, diamond, Gr. ?. Perh. the corruption is due to the influence of Gr. ? transparent. See Adamant, Tame.] 1. A precious stone or gem excelling in brilliancy and beautiful play of prismatic colors, and remarkable for extreme hardness. Note: The diamond is native carbon in isometric crystals, often octahedrons with rounded edges. It is usually colorless, but some are yellow, green, blue, and even black. It is the hardest substance known. The diamond as found in nature (called a rough diamond) is cut, for use in jewelry, into various forms with many reflecting faces, or facets, by which its brilliancy is much increased. See Brilliant, Rose. Diamonds are said to be of the first water when very transparent, and of the second or third water as the transparency decreases. 2.
