Lazurite and hauyne seem to have the same structure and both are sulfate-dominant minerals. [13] Lazurite is a pigment (opalescent) and has a bright blue streak (especially as a component of the semiprecious stone lapis lazuli). Many hauynes have a white or pale blue streak and are translucent.
Azure spar, sometimes azur-spar (German: Lazur spath, Blau spath) is a trivial and commercial, partly obsolete name for several of the most famous bright blue or blue-colored minerals, which also have similar names, most notably for lazurite and azurite, [1]: 14 and also for the less commonly used lazulite.
