Lazurite, old name Azure spar [7]: 14 is a tectosilicate mineral with sulfate, sulfur and chloride with formula (Na,Ca) 8 [(S,Cl,SO 4,OH) 2 |(Al 6 Si 6 O 24)]. It is a feldspathoid and a member of the sodalite group. Lazurite crystallizes in the isometric system although well‐formed crystals are rare.
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.
In April 2021, the developers announced plans to launch a Kickstarter project later in the month to turn the demo into a full game.

Lazulite or Azure spar [6]: 14 is a transparent to semi-opaque, blue mineral that is a phosphate of magnesium, iron, and aluminium, with the chemical formula (Mg,Fe 2+)Al 2 (PO 4) 2 (OH) 2. [3]
The major component of lazurite is a complex sulfur-containing sodium-silicate (Na 8–10 Al 6 Si 6 O 24 S 2–4), which makes ultramarine the most complex of all mineral pigments. [10] Some chloride is often present in the crystal lattice as well. The blue color of the pigment is due to the S − 3 radical anion, which contains an unpaired ...
