Haüyne or prismatic azure spar is a transparent or translucent mineral, similar to lazurite, in composition sodium and calcium aluminosilicate with the ideal formula (Na,Ca) 4-8 Al 6 Si 6 (O,S) 24 (SO 4,Cl) 1-2 having a blue or blue color, sometimes with a greenish tint, [5] was also known among the azure spars.
Lapis lazuli (UK: / ˌ l æ p ɪ s ˈ l æ z (j) ʊ l i, ˈ l æ ʒ ʊ-,-ˌ l i /; US: / ˈ l æ z (j) ə l i, ˈ l æ ʒ ə-,-ˌ l i /), or lapis for short, is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color.
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.
