Greyish to purple, excellent crystal. Crystals such as this one must be very rare. There is probably work to be done on this specimen as Dunn's description was a work-in-progress. This may be a pseudomorph. Nonetheless a very interesting piece with associated bright yellow crystal grain of Kombatite to 1mm.

Museum quality specimen of opaque greenish yellow super-sized crystals of Saleeite. The largest crystal is 1.7cm. Many of the other crystals are tabular and stacked like pages in a book fanned out. Formerly in the Colorado School of Mines collection. See prov. tab for older labels. Ex. Barbara Cureton collection.
The color match is most like the first photo. I had to "tweek" the color in the remainder of the photos since, as usual, the digital process washes the true color out.
This specimen is remarkably similiar to the one in the second edition of Encyclopedia of Minerals by Roberts & Campbell.
