CANTON — The St. Lawrence County Rock & Mineral Club's 42nd annual show Saturday and Sunday brought together an intergalactic world at the Canton Sportsmen's Club.

Meteorites dug up in Argentina weighed down the table of Jack A. LaCroix, Malone, with their dense content of iron nickel.

The Campo del Cielo meteorites, priced from $15 to $10,000, were the result of a single fall 4,000 to 6,000 years ago that was first noted in 1576.

"I buy them by the kilo," Mr. LaCroix said. "Ninety-nine percent of what I sell is on the Internet. I sell more out of the country than in."

Mr. LaCroix, a former car dealer, became interested in rocks and crystals in 2003 when his grandson, David J., cajoled him into going to the Herkimer diamond mines and Schroon Lake caverns to hunt for minerals.

"I got hooked. It was supposed to be a hobby and it just mushroomed," Mr. LaCroix said. "How many people can make money with their hobby? We're like kids when the shipments come in and we start going through them."

Club President William F. deLorraine was excited to see the meteorites.

"I got one myself," he said. "I've been fascinated by them since I was a kid."

Max M. Impoyi brought free-form polished malachite and other gems mined in his native country of the Democratic Republic of the Congo.

"We mine it and we carve it in the workshop," Mr. Impoyi said. "We sell to different shows and we ship some to dealers. They use it for many things."

Mr. Impoyi came to the Canton show for the first time last year after meeting Schuyler W. Alverson, one of the club's founders, at a show in Arizona. With a booth at the New York State Fair, it was easy to set up a second stall at the county show.

New this year was Jacek P. Tomasik, a native of Germany and resident of New York City, who brought Baltic amber.

"My parents do this usually but I'm helping them out. They travel to shows in Maine, Detroit, Cincinnati. They didn't know about this show before," he said. "The Russians dig the amber and it's manufactured in Poland or Lithuania. We import it."

Janet L. Rowe, Canton, makes an annual pilgrimage to the show.

"My nephew used to be a vendor, so we got hooked on it," she said. "I like the tumbled stones, obsidian, all the pretty things."

Mr. LaCroix pointed to a nondescript rock on his table.

"This is the strangest stuff we sell, dinosaur crap," he said.

Coprolite is fossilized dung.

"I've got a shirt that says, 'coprolite happens,'" the younger Mr. LaCroix said.
