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.

Lazurite and hauyne seem to have the same structure and both are sulfate-dominant minerals. [14] 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.
The color azure ultimately takes its name from the vivid-blue gemstone lapis lazuli, a metamorphic rock. Lapis is the Latin word for "stone" and lāzulī is the genitive form of the Medieval Latin lāzulum , which is taken from the Arabic لازورد lāzaward [laːzwrd] ( listen ⓘ ), itself from the Persian لاژورد lāžaward , which ...

Persian blue: made by grinding up the mineral Lapis lazuli. The most important mineral component of lapis lazuli is lazurite (25% to 40%), a feldspathoid silicate mineral with the formula (Na,Ca) 8 (AlSiO 4) 6 (S,SO 4,Cl) 1–2. Cobalt pigments. Cobalt blue (PB28): cobalt(II) aluminate. Cerulean blue (PB35): cobalt(II) stannate. Cerium uranium ...
It may be confused with lazurite, lapis lazuli or azurite. The type locality is in Freßnitzgraben in Krieglach, it's also found in Salzburg, Austria; Zermatt, Switzerland; Minas Gerais, Brazil; Lincoln County, Georgia; Inyo County, California; the Yukon in Canada; and elsewhere. It was first described in 1795 for deposits in Styria, Austria. [3]
