ifuckingloveminerals:HemimorphiteSa Duchessa Mine, Oridda, Domusnovas, Carbonia-Iglesias Province, Sardinia, ItalyHemimorphite is a zinc silicate mineral with OH groups in its structure. It’s generally colorless although occasionally is this spectacular blue color. Even after a bit of searching I can’t tell what chemical creates the color, wonder if anyone knows. Most deep colors in minerals are produced by minor components that, when put in the structure, interact with visible light in very strong ways. -- source link
