    CH-UNGR (Ungrouped Chondrite) Subtype 3.05
    Western Sahara
    Covered in fusion crust on the reverse, this is the 5717th meteorite recovered and classified from the North West African grid of the Sahara Desert.

    Of the tens of thousands of chondritic meteorites known to exist (meteorites which contain silica-rich spherules), it is also one of just 14 that are unclassifiable and designated as being ungrouped (CH-UNGR). NWA 5717 is also the only meteorite within this select group that is a member of an even more select group: it features a 3.05 subtype which makes it among the most primitive planetary matter known. Specifically, unlike 99.9% of all meteorites, the constituents of this meteorite are unchanged since their origins in the early solar nebula. As a result of it being unique, scientists concluded that NWA 5717 originates from a previously unknown parent body. Only six pounds of similarly primitive planetary material was known to exist prior to NWA 5717's discovery. States researcher Dr. Anthony Irving of Washington University, "There will most certainly be a great deal of research done on 5717 in years to come." Devoutly sought-after by scientists, unmetamorphosed meteorites like NWA 5717 are the raw ingredients from which our solar system formed. More than half of the NWA 5717 mass will be placed in museums and institutions and scant material will be available to the collecting community. For the sophisticated collector, this specimen features two lithologies packed with a galaxy of chondrules which are observable from three cut and polished faces with crust enshrouding the reverse. From the Macovich Collection, this offering is accompanied by the 2010 Lunar and Planetary Science Conference abstract entitled "The Extra-Ordinary Chondrite: NWA 5717." 35 x 33 x 39 mm (1.33 x 1.33 x 1.5 inches) and 76.3 grams.
