Jewish (Ashkenazic): Americanized form of a Jewish surname,
spelled in various ways, derived from modern German Diamant,
Demant ‘diamond’, or Yiddish dime(n)t, going back to
Middle High German diemant (via Latin from Greek
adamas ‘unconquerable’, genitive adamantos, a reference
to the hardness of the stone). The name is mostly ornamental, one of
the many Ashkenazic surnames based on mineral names, though in some
cases it may have been adopted by a jeweler.
English:
variant of Dayman (see Day). Forms with the excrescent
d are not found before the 17th century; they are at least in
part the result of folk etymology.
Irish: Anglicized form of
Gaelic Ó Diamáin ‘descendant of Diamán’,
earlier Díomá or Déamán, a diminutive of
Díoma, itself a pet form of Diarmaid (see
McDermott).
