Decked out in their "Star 98 Diamond Dive" T-shirts, 40 wildly enthusiastic contestants pounced on a 6-foot-tall, 800-pound wedding cake to try to find a $2,000 diamond engagement ring that was baked inside.

They destroyed the cake in a matter of seconds as onlookers at the Grand Teton Mall in Idaho Falls, Idaho, this past Saturday watched in amazement. A video of the event shows the cake being enveloped by a sea of humanity.

The 2nd Annual Diamond Dive was sponsored by local radio station Star 98 in conjunction with a local baker, who designed the cake, and a local jeweler, who provided the jewelry. In all, 16 rings were hidden in the cake, 15 of which were non-precious and represented other prizes. The grand prize was a genuine .50-carat princess-cut diamond engagement ring.

In order to qualify for the Diamond Dive, listeners of Star 98 had to call the station at designated times, starting on April 18. Forty people were eventually selected to participate in the messy, no-holds-barred cake-diving event.

To make the massive cake, the baker's team had to use 165 cake mixes, 54 dozen eggs, 192 pounds of sugar, 72 pounds of shortening and a quart of cake flavoring.

As the excitement unfolded on Saturday, the only person who knew the exact location of the diamond ring was the baker.

As if describing an Olympic event, Star 98 program manager Preston Lee joked to Local News 8, "So these are dedicated people. They've been training. They've been warming up for the past few years. Now, all that training is coming together for one moment, for the diamond dive."

All 16 rings were found within 15 minutes, and emerging victorious with the genuine engagement ring was Nick Musetti, who admitted he didn't have a significant other.

"I'm thinking about selling it because I don't have anyone to give it to," he lamented.
