    FINE SLICE OF THE ASTEROID "VESTA"
    NWA 4664 - Achondrite (Diogenite, polymict brecchia)
    Algeria
    First discovered in 2006, this is a complete slice from a fall comprising a number of separate stones but amassing only 20 kg in total were recovered. It has been classified as a diogenite, a specific type of achondrite meteorite originating deep within the crust of the asteroid 4 Vesta. They are named after Diogenes of Appolonia, the fifth century BC Greek philosopher who was the first to identify the extraterrestrial origin of meteorites. The present slice retains a complete rind of pale rough fusion crust, and displays on both sides the lovely speckled patterning of the stone's interior. The NWA 4664 is an unusual diogenite in that it contains characteristic broken pyroxene crystals along with countless small clasts of very dark magnesium-rich olivine and plagioclase feldspar. This wonderful natural composition is displayed to best advantage with a flat finish on one side and a glossy polished finish on the other with a lovely spacey blue-green tinge, of roughly triangular form, approximately 4 1/4 x 3 5/8 x 1/8 inches and weighing 64.32 grams.
