F26RE8: Dissakisite-(Ce) on Dolomite
The mineralogical literature is not clear if we are dealing with Dissakisite-(Ce) or Allanite-(Ce). Both species are the end species of an isomorphic range and most of the samples from Trimouns present colored zones where the darker ones correspond with Allanite-(Ce) (as it is richer in iron) and the lighter areas are Dissakisite-(Ce) We have not analyzed this sample but the uniform color, and especially it lightness, indicate that it is poor in iron so we guess that it is Dissakisite-(Ce)

TC88AF7: Djurleite-Chalcocite intergrowth
A novelty at Tucson 2017. Parallel growth of very flattened and bright crystals. These samples were mined carefully over seven months in the Aït Ahmane area (it seems not in the same shafts that produced the famous Gersdorffites) and, due the sharpness of the crystals and their size, this find will contend for being the world's best for the species. We’ll send to the buyer a copy of the analysis that indicates an intimate intergrowth of Djurleite and Chalcocite.
