Jewish (Ashkenazic): from an Anglicized form of a metonymic occupational name for a diamond worker, derived from German Diamant, French and Dutch diamant ‘diamond’, or Yiddish dime(n)t, from medieval Latin diamas, genitive diamantis, and ultimately from Greek adamas ‘unconquerable’, genitive adamantos, a reference to the hardness of the stone.
English: from the rare Middle English female personal name Diamand, derived from Old French diamaunt, diamaund ‘diamond’, found in Middle English as diamound, deamaunt, and deamon. The name may alternatively be a variant of Daymon or a pet form of the Middle English personal name Day , to which the hypocoristic suffix -man has been added.
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 ).
