A meteor(陨星) that exploded over Russia’s Ural mountains and sent burning to earth has set off a rush to find fragments of the space rock which hunters hope could fetch thousands of dollars a piece.

Friday’s explosion and following shockwave shattered windows, injured almost 1200 people and caused about $33 million worth of damage, said local authorities.

It also started a “meteorite rush” around the industrial city of Chelyabinsk,where groups of people have started combing through the snow and ice.

“The price is hard to say yet… The fewer meteorites that are discovered, the higher their price is.” Said Dmitry Kachkalin, a member of the Russian Society of Amateur Meteorite Lovers.

Meteorites are parts of a meteor that have fallen to earth.

Scientists at the Urals Federal University were the first to announce a significant find-53 small, stony, black objects around Lake Chebarkul, near Chelyabinsk, which tests confirmed were small meteorites.

The fragments were only 0.5 to 1 cm across but the scientists said larger pieces may have crashed into the lake, where a crater in the ice about eight metres wide opened up after Friday’s explosion.

“We just completed tests and confirm that the pieces of matter found by our experts around Lake Chebarkul are really meteorites.” said Viktor Grokhovsky, a scientist with the Urals Federal University and the Russian Academy of Sciences.

Many other people were in the area just hoping to find a meteorite after what was described by scientists as a once-in-a-century event.

Residents of a village near Chelyabinsk searched the snowy streets, collecting stones they hoped prove to be the real thing. But not all were ready to sell.

“I will keep it. Why sell it? I didn’t have a rich lifestyle before, so why start now?” a woman in a woollen hat and winter jacket, clutching a small black pebble(小圆石), told state television.

The Internet was filled quickly with advertisements from eager hunters hoping to sell what they said were meteorites - some for as little as 1,000 roubles ($33.18).

One seller of a large, silver-hued rock wrote in an advertisement:” Selling an unusual rock. It may be a piece of meteorite. It may be a bit of a UFO. It may be a piece of a rocket!”
