1 Fig. 5 Confirmation of the phyllosilicate phlogopite mineral found adjacent to lazurite particles using micro-Raman spectroscopy. Confirmation of the phyllosilicate phlogopite mineral found adjacent to lazurite particles using micro-Raman spectroscopy. Matching micro-Raman spectra of the colorless particle and a published reference spectrum of phlogopite (23), an accessory mineral that co-occurs with lazurite in natural lapis lazuli stone. Inset: Optical image of archaeological colorless particle. Raw data are provided in data file S3. Credit: A. Radini, E. Tong, R. Kröger. A. Radini et al.
