Database of Raman spectroscopy, X-ray diffraction and chemistry of minerals

Important Update News

The RRUFF Project is being updated to improve its interface and content. The beta version of the update is accessible to the public at RRUFF.net. New data is only being added to the beta site. Please note that it is in development, and some components are not functional. Existing RRUFF.info links will resolve to the new site after RRUFF.net is officially released.

We are grateful to NASA for the funding of this effort.

We host articles and citations in collaboration with the Canadian , American , British , Japanese , French , Russian , and Italian mineral societies.
