The Mineral scorzalite
Scorzalite is an uncommon deep-blue mineral that forms a series with Lazulite. Lazulite is the magnesium-rich end member of the series, and Scorzalite is the iron-rich end-member. Scorzalite was first identified in 1947, and is named after the Brazilian mineralogist Evaristo Penna Scorza (1899-1969).
