The RRUFF™ Project is creating a complete set of high quality spectral data from well characterized minerals and is developing the technology to share this information with the world. Our collected data provides a standard for mineralogists, geoscientists, gemologists and the general public for the identification of minerals both on earth and for planetary exploration.
Taking out the guess work
Users of Raman instruments can compare their Raman patterns to those from our mineral samples with confidence.
X-ray diffraction analyses from powder and single crystal are used to identify and determine crystallographic properties unique to each mineral. Electron microprobe analysis is used to determine the chemistry of each mineral. The RRUFF™ Project also provides sample photos**, as well as references (in downloadable .pdf with permission from certain publishers). **Read more about RRUFF™ project photography.
Applications for the database
Raman professionals everywhere already have a need for comparative databases in their field. Growing demand for this type of comprehensive mineral database is due in part to the increase in the popularity of miniature Raman devices. An array of portable and hand-held instruments employing Raman technology is already available on the market, and the purchase price is steadily decreasing.

A note to gem and mineral collectors, dealers, and enthusiasts:
You can help! We need thumbnail samples of very rare minerals to complete the RRUFF™ library. If you are interested in getting involved with the project or donating samples:
Thanks to our Sponsor and contributors
We thank our generous sponsor Michael Scott, and the many individuals & corporations who have donated samples to the project. Additional funding has been provided by the National Science Foundation under Grant No. EAR-0622371 and by NASA/JPL through the Strategic University Research Partnership program.
