Editing Lazurite (section)

== Structure ==
Lazurite and [[hauyne]] seem to have the same structure and both are sulfate-dominant minerals.<ref>{{Cite journal |author1=Moore, T.P. |author2=Woodside, R. W. M. |year=2014 |title=The Sar-e-Sang Lapis Mines |journal=Mineralogical Record |volume=45 |issue=3 |pages=281–336}}</ref> 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 difference might be a consequence of the [[Redox potential|redox state]] (sulfate to sulfide ratio).<ref name=Sapozhnikov/><ref>{{Cite journal |vauthors=Hettmann K, Wenzel T, Marks M, Markl G |year=2012 |title=The sulfur speciation in S-bearing minerals: New constraints by a combination of electron microprobe analysis and DFT calculations with special reference to sodalite-group minerals |journal=American Mineralogist |volume=97 |issue=10 |pages=1653–1661|doi=10.2138/am.2012.4031 |bibcode=2012AmMin..97.1653H |s2cid=54921328 }}</ref>
