The Mineral Spectroscopy Server

On-line information on the absorption spectra and color of minerals.

• Information on the origin of color in minerals and gems
• Data files available as ASCII (wavelength, absorbance) pairs [more than a thousand files]
• Images of selected mineral spectra
• Extensive references to mineral optical spectroscopy  [more than 600 references] 

  PLUS

• information on manganese dendrites [They are not pyrolusite!]
• information of desert varnish
• information on ametrine [amethyst - citrine bicolored quartz]
• information on painite [ formerly one of the rarest minerals]
