DEPUTATSKOYE, Russia — Ever since the meteor exploded somewhere over this impoverished Siberian town, Larisa V. Briyukova wondered what to do with the fist-size stone she found under a hole in the roof tiles of her woodshed.

On Monday, a stranger knocked on her door, offering about $60, Ms. Briyukova said. After some haggling, they settled on a price of $230. A few hours later, another man pulled up, looked at the hole in the roof and offered $1,300.

“Now I regret selling it,” said Ms. Briyukova, a 43-year-old homemaker. “But then, who knows? The police might have come and taken it away anyway.”

On Friday, terror rained from the skies, blowing out windows and scaring people over an enormous swath of Siberia. But by Monday, for many people what fell from the sky had turned to pure gold, and it touched off a rush to retrieve the fragments, many buried in deep February snows.
