You know you're in a niche market when your inventory has to survive a 160,000-mph entry through the Earth's outer atmosphere.
"It's interesting how you price meteorites," said James Hyslop, a specialist at Christie's London who has organized an April 20 sale of 76 meteorites. Among the factors that affect prices, he noted, are meteorites' scarcity and the fact that available stock is only occasionally replenished. (A meteor explosion over Siberia in 2013 added significantly to available material.) "It can really be quite difficult."
Historically, meteorites were valued by gram, Hyslop said. The heavier they were, the more expensive. Recently, however, collectors have begun to take both aesthetic and historic aspects into consideration. "The diamond industry uses the four C's," Hyslop said. "We use the four S's: size, shape, science and story."
Size is obvious: more meteorite, more money; shape, less so.
"When most meteorites fall to earth, they tumble chaotically," Hyslop explained. "You don't have them plowing straight down." On the rare occasion that a meteorite does head straight down, its surface heats, then melts, and "you get this wonderful heat shield that has a perfect parabola to it." Parabola-shaped meteorites, in turn, are much more expensive than others.
The scientific aspect of meteorite valuation is more complicated and is often combined with its story.
"Some of the most-sought-after ones are the pallasite slices and spheres that have peridot," Hyslop said, referring to pieces of a certain type of meteorite embedded with the greenish gemstone. "Others, like the lunar meteorite, are always incredibly popular." Hyslop was referring to a piece of the moon that was blown off the satellite by the impact of a very large meteorite, floated through space for possibly millions of years and then collided with the Earth. There are even a couple of meteorites from Mars.
Estimates for the meteorite lots range from $355 to more than $1.1 million for the world's largest "oriented" meteorite (which means it has that parabolic shape) embedded with extraterrestrial gemstones.
"If you were to cut a slice through it, you'd see this iron matrix of olivine crystals, some of which are so high-quality they're technically gemstones," Hyslop said.
Many of the meteorites come from long-standing private collections, while others are being sold by museums that exchanged slivers of their own specimens for new, "incredibly rare" meteorites, Hyslop said. One collector at the Christie's sale will be able to buy a piece of the Willamette meteorite, currently on display at New York's American Museum of Natural History (estimate: $99,470 to $142,100).
