CNN: Heart-shaped meteorite up for auction on Valentine's Day

Description

Sarah Crowther, from the University of Manchester's School of Earth and Environmental Sciences, told CNN that the specimen belongs to an uncommon group of iron meteorites known as IIAB. "There are currently 134 type IIAB iron meteorites, out of a total of over 60,000 known meteorites, so this type is fairly rare," Crowther said.

"The price does seem high for an iron meteorite," she added. Other fragments of the same meteorite retail for far less: "In the range of $1-$4 per gram," she said, "whereas even the lower end of the estimated price range for this is almost $30 per gram."

What's responsible for the high value of the meteorite? "The shape, the regmaglypts and the size of the sample," Crowther said.
