It is a basaltic shergottite. It was about 15 cm x 10 cm and weighed 2,015 grams. Analysis show these are indistinguishable from those of DaG 476 and all four meteorites are likely paired. The DaG 476 is less weathered than the DaG 489 or 670. All four have been determined to be Martian meteorites by comparing isotopic analyses of these meteorites with data gathered by the Viking probes which landed on Mars in the 1970's.
Martian meteorites are much rarer than diamonds however.
