Small sample, about 3 mm across, of a Khatyrkite-bearing meteorite discovered in the mineral collection at the Museo di Storia Naturale in Florence, Italy. On January 1, 2009, Paul Steinhardt's Princeton lab identified the signature diffraction pattern of a quasicrystal embedded next to the khatyrkite and other minerals, thereby establishing evidence of the first natural quasicrystal. The sample is mounted on a pyramid-shaped piece of clay next to a 5 cent (euro) coin to illustrate its size. Mineral

FOV 2.4 x 2.9 mm. Found August 1997. MOB coll. This specimen was confirmed at the Canadian Museum of Nature. See http://www.mindat.org/photo-166788.html for more information. The color is more orange than red. But it is impossible to visually distinguish khomyakovite from manganokhomyakovite, ferrokentbrooksite or other eudialyte group members at MSH. The environment is igneous breccia rather than a miarolitic cavity. From: Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada. Mineral
