For those interested or who purchased some of this, I got an email from Tony Irving with more detailed info on the NWA 6291 angrite.
"NWA 6291 Achondrite (angrite, metal-rich) Annealed breccia composed of Al-Ti-diopside (Fs10.8+/-0.05Wo53.0+/-0.05, FeO/MnO = 114, Al2O3 = 7.7-7.9 wt.%, TiO2 = 1.3 wt.%), calcic olivine (Fa40.9+/-0.05, FeO/MnO = 94-95, CaO = 1.3-1.5 wt.%), pure anorthite, Cr pleonaste spinel, altered kamacite (~8 vol.%) and troilite. Anorthite occurs as large (up to 3 mm) angular clasts and also as thin coronas around spinel grains. Secondary terrestrial weathering products include iron hyroxides (in veinlets) and minor calcite. This specimen is paired with NWA 2999 (and other stones)" Many thanks go out to Tony Irving, he is a great guy to work with!
