Aquarium worker Michael Whyte said after advertising official Bob Pirrmann lost his wedding ring while diving in the tourist site's 200,000-gallon Giant Ocean Tank, the beloved item became a veritable "needle in a haystack," The Boston Globe said Thursday.
"It was one of those things where I thought, 'It's got to be here someplace,'" Whyte said.
Despite the odds of finding the tiny piece of jewelry in the large display tank, Whyte located Pirrmann's ring on a piece of finger coral Sunday.
Whyte said the ring was returned to Pirrmann, who lost it in July while diving in the four-story tank.
Though unusual, it was not the oddest discovery in the open-topped tank to date.
"We have drawerfuls of sunglasses," he told the Globe. "One time, a baby spit a pacifier, and when I went down to get it, a porcupine fish had it in its mouth."
