Redledgeite is a very rare mineral chromium-titanium oxide of the Hollandite group and is found in only three localities worldwide. This locality is perhaps the best. This specimen is extremely rich with thick patches of pistachio green acicular crystaks to about 1mm. The purple mineral is Shuiskite.

This occurence has been confirmed, and this is one of the better specimens I found in Tucson. My sources tell me that maybe 12-15 Redledgeites were found. This is of course hard to verify. The cluster of the Redledgeite is 10x18mm and there are other smaller clusters. The matrix is a dark green Clinochlore or a purple Diaspor and or Amesite. In-hand it is dark green. This is most likely the best occurence in the world out of the three reported. This occurence is the fourth and has not been documented. These crystals are a metallic green and reach about 6mm. It is a very rich specimen.
