diamant, corrupted, fr. L. adamas, the hardest iron, steel,

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.
