The Digital Rockhound’s Companion 2.0 is a database application that is the compilation of a lifetime’s interest in rock hounding. I designed this application for my personal use and I actively use the application to maintain my mineral collection.

The focus of the application is provide location information for mineral collecting sites and mines and cross-reference against reported mineral occurrences and also against specimens in your mineral collection. Having more specific information about a mineral location adds interest and value to a specimen.
