MinMax Database
MinMax is a database of minerals and worldwide collecting locations. The main aspect is a online database of mineral sites including their location, the mineral list, mineral descriptions, collectors information, pictures, links, shows and more. Every page and area is available in english or german!

mindat.org
an online mineralogical reference and locality resource for collectors and mineralogy students worldwide

Mineral Data
thousands of pages with information, photos and spectra. This is the ever growing list of physical, chemical (more than 3650 minerals) and optical data (600 minerals), photos (more than 60,000 colour photos of around 1900 minerals, thin sections, more than 100 scanning electron microscope images of more than 50 minerals and transmission electron microscope images) and vibrational spectra of the minerals available in this database. The original spectra are available for selected minerals on request. Data are on the web only available as images of the spectra.

Catalog Mineralov
This mineral database contains more than 1000 individual mineral species descriptions (in Russian) with mineral specimen images

WWW-MinCryst
is a Crystal Structure DataBase for Minerals containing 4600 entries (2260 unique names, 2340 varieties on composition, structure and T-, P-conditions of synthesis). Information Card includes: Name, Specification, Crystal Chemical Formula, Space Group, Z, Unit Cell Parameters, Coordinates of Atomic Position, References, etc. Search on chemical composition and crystal chemical characteristics are realized. Special search regime allows to identify your sample on set of experimental d(hkl) in view of chemical composition. Calculated X-ray Powder Diffraction Standards (CPDS) and Patterns in full and short forms, as well as Images of Crystal Structure Model and X-ray Powder Diffraction Line Diagram can be displayed.
