diamond

diamond: [13] Diamond is an alteration of adamant, a rather archaic term which nowadays refers to hard substances in general, but formerly was also used specifically for ‘diamond’. The alteration appears to have come about in Latin of post-classical times: adamant- (stem of Latin adamas) evidently became Vulgar Latin *adimant- (source of French aimant ‘magnet’), which appears to have opened the way to confusion, or at least association, with words beginning dia-. The result was medieval Latin diamant-, which passed into English via Old French diamant.

diamond (n.)

early 14c., from Old French diamant, from Medieval Latin diamantem (nominative diamas), from Vulgar Latin *adiamantem (altered by influence of the many Greek words in dia-), from Latin adamantem (nominative adamans) "the hardest metal," later, "diamond" (see adamant). Playing card suit is from 1590s; Sense in baseball is American English, 1875.
