QEMSCAN is a fully automated, non-destructive, micro-analysis system that provides rapid, statistically reliable and repeatable, mineralogical, petrographic and metallurgical data, from virtually any inorganic, and some organic, materials.

RocKeeper is software designed to curate your collection the way it was meant to be curated. No awkward spreadsheets, no cumbersome forms adapted from other software. Just a nice, clean tool designed from the ground up to really showcase your rock collect

Dakota Matrix was founded in 1996 and has offered systematic and rare mineral specimens online since 1998.
