Jewelry, Gems, & Minerals/Aulmauracite?


Hi there.. Do you have any idea what exactly this mineral is that is being sold as a 'wonder' rock (called Aulmauracite) on certain new age websites?

Aulmauracite is not an approved mineral name and is not part of any mineralogical databases. From the few pictures and vague reference to geochemical assays that float around on the internet and in books, the "wonder mineral" is most likely specular hematite (Fe2O3). A simple test would be to drag the aulmauracite specimen across a unglazed porcelain plate (back of a bathroom tile for example). It should leave a reddish brown line indicating the presence of hematite. If you have a sample and would like it tested or assayed, we would do it for free as part of our Metropolitan State University of Denver community outreach. For details please see:

I can answer questions concerning minerals, mineralogy, gems, metals, and anything that has to do with geology. However, I am NOT a jeweler. Questions about values, settings, gem stone cuts and appraisals are best directed to other experts on this site. I can however aide in the identification of unknown mineral materials. As a public service and part as training for new geoscientists, our university department provides FREE mineral identification for individuals. Please contact me for details or go to for details..
