Ulmannite is a rare mineral discovered in California in 1893. It is named after the German chemist Fritz Ulmann. The word is pronounced as "uhl-muh-nahyt", with the first syllable pronounced as "uhl" in "hull" and the "-mannite" part pronounced as "mu-nahyt". The spelling follows the principles of English orthography, with the "u" vowel pronounced as "uh" and the double "n" indicating a nasal "n" sound. Ulmannite is a sulfide mineral that is highly prized among collectors for its beauty and scarcity.
An ore of nickel and antimony, found chiefly in the copper-mines of the Westerwald, of a bluish-grey colour.
