AmethystGalleries.com
Amethyst Galleries.com describes over 600 mineral species (and varieties) and more than 5000 specimens, together with several ways of accessing these descriptions. The descriptions include searchable mineralogical data, plus other information of interest to students and rock hounds. Galleries.com was the first rock shop on the Internet, going live (with a numeric IP) in the fall of 1994, and under the domain galleries.com in the spring of 1995.

Mindat.org
MinDat.org is the largest mineral database and mineralogical reference website on the internet. This site contains worldwide data on minerals, mineral localities and other mineralogical information.

RRUFF.info
The RRUFF™ Project is an integrated study of the chemistry, crystallography, Raman and infrared spectroscopy of minerals. 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. The 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.

Webmineral.com
The Webmineral.com site contains mineral data on individual species that are linked to mineral tables by crystallography, X-Ray powder diffraction, chemical composition, physical and optical properties, Dana's New classification, Strunz classification, mineral specimen images, and alphabetical listings of mineral species. There are extensive links to other sources of mineral data and information.
