Fig. 6: UV/Vis/NIR reflectance spectra of a reference lapis lazuli (lazurite mineral) and unknown blue paint samples from the Enkleistra. The identification of lapis lazuli in the blue paints was determined by its distinctive electronic spectrum displaying a strong and broad absorption around 600 nm in the visible caused by the S3 paramagnetic radical anion in lapis lazuli.
