diamond  (d-mnd)
A form of pure carbon that occurs naturally as a clear, cubic crystal and is the hardest of all known minerals. It often occurs as octahedrons with rounded edges and curved surfaces. Diamond forms under conditions of extreme temperature and pressure and is most commonly found in volcanic breccias and in alluvial deposits. Poorly formed diamonds are used in abrasives and in industrial cutting tools.

A similar superstition was once prevalent, as I have heard, in ancient Greece and Rome; not applying, however (as in India), to a diamond devoted to the service of a god, but to a semi-transparent stone of the inferior order of gems, supposed to be affected by the lunar influences--the moon, in this latter case also, giving the name by which the stone is still known to collectors in our own time.
"That is but right," said the unknown, after a long silence, "but as I have no more money, as you have seen, and as I yet must retain the apartments, you must either sell this diamond in the city, or hold it in pledge.
And as a proof of what I say she commanded me to show you this diamond, which she thinks you know.
