510,10 $
NWA 12731 is a rare and fresh rumuruti type R5 weighing only 29 grams.
The R chondrite group does not clearly belong to any of the major chondrite classes (ordinary, carbonaceous, enstatite); R chondrites have sub-solar Mg/Si and refractory/Si ratios, oxygen isotopic compositions that are above the terrestrial fractionation line and ordinary chondrites, and strongly oxidized mineralogy.
The first R chondrite, Carlisle Lakes, was found in Australia in 1977.
The main mass (19.5 g) of this meteorite is for sale, the rest was used to make the classification.
