This meteorite was discovered, buried, about 100 kilometers north-east of Laayoune (Western Sahara), at a place called Chouichiyat (which can also be written Chwichia).

NWA 7831 is a bit like the meteorite of Tatahouine in structure with its yellow-green crystals of orthopyroxene except the fact that they are not opaque. It is extremely brittle and must be handled with delicacy.
