I've recently started branching out from meteorites (to the alarm of my husband!) to semi-precious gemstones. I prefer the obscure ones, and thought I'd found a winner when I came across "mawsitsit", a chromium-rich relative of jade from Burma. The advertising copy on the website says that the mineral components of mawsitsit are found in some meteorites and also goes by the trade name of "Kosmochlor". Has anyone ever heard of this? I don't doubt that traces of the mineral might occur in meteorites, but not in useable quantities, i.e, make gems out of it. The only "green" meteorites I know of are Tatahouine and Bluff (b), and of course everyone's favorite, the "emerald" meteorite!
Chemical composition of the stone is NaCrSi2O6 (Ureyite) and NaAlSi3O8 (Albite) mixed together. The ureyite is what is supposed to be in meteorites, as a very dark green, almost black, mineral.
