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.

An amazing specimen with several gorgeous minerals. The main mineral of note is the Redledgeite which occurs as black, needle-like crystals to 2mm. These are very large for the species. As like the type locality the Redledgeite also forms green hair-like crystals as seen in the photos.
In addition this specimen is covered with good sized crystals of beautiful green Uvarovite crystals to 2.5mm but are mostly 1mm or less. There is also a large chromium Titanite crystal to 1.7mm and purplish Amesite.

Redledgeite is a chromium - titanium oxide with barium. On this specimen are vivid green or yellowish green fibrous crystals. The Handbook of Mineralogy notes that when Redledgeite is low in iron it exhibits a vivid green internal color. This may be the case with this specimen. The fibrous crystals reach about 3mm with near total coverage but sharing the matrix with clinochlore(?). From what I am told maybe a dozen of these were found. This is the best one I have seen. It is yet, an undocumented locality, but the same locality as the Uvarovite and green chromium rich Titanite.
