Diamond found in Wisconsin well - WKOW 27: Madison, WI Breaking News, Weather and Sports

ST. CROIX COUNTY (WKOW) -- A Wisconsin man says he found a 1.22-carat diamond in his friend's well.

The Pierce County Herald reports on its web site that Dan Fagnan, of St. Croix County, was recently allowed to pan through a wet pile of rocks and sand pulled from 120 feet below ground and spotted a tiny transparent rock that he first thought was a piece of glass.

"Everyone thinks I'm a fruit loop for panning for gold," he said with a laugh.

They may not think that anymore.

Fagnan says a nearby jeweler determined the stone was a diamond. That jeweler told the newspaper the stone likely pushed southward from Canadian volcanic activity and was left in Wisconsin after the Ice Age.

Fagnan plans to place the stone in a necklace for his soon-to-be-born child.
