Lazulite

Lazulite, or AZURITE, a mineral long confounded with Lapis Lazuli (q.v.), but, although somewhat similar in colour, very different in composition; consisting chiefly of phosphoric acid and alumina, with magnesia and protoxide of iron. It occurs imbedded in quartz, or in fissures in clay-slate, in Styria, North Carolina, Brazil, &c.
