Tut Jewel Formed By Asteroid Impact

The central jewel in King Tutankhamen's pectoral gear may have been literally out of this world—the result of an asteroid that exploded above the Sahara—according to Mark Boslough, a researcher at Sandia National Laboratories. In 1998 researchers elsewhere determined that Tut's jewel wasn't chalcedony but an unusual type of desert glass. Boslough, who was part of a team that created a computer simulation to predict what would happen when comet Shoemaker-Levy hit Jupiter, was later enlisted to figure out if the gem was meteoric in origin.

Boslough used Sandia's Red Storm supercomputer to ask what conditions would be required to melt Saharan sand into glass. The winning scenario: a 400-foot-wide stony asteroid that slammed into the air at 12 miles a second and exploded. For 20 seconds the resulting fireball would have been hot enough to melt quartz on the ground, creating glass that can still be found in the desert. Ancient Egyptians might have rightly recognized such ornaments as more precious than gold.
