Stephen Walker, an Andover specialist in Celtic jewelry, said Mark Rubinstein of Coral Springs was out hunting pythons earlier this year when he discovered the partially-melted gold, sapphire, and diamond jewel among some debris, ABC News reported Tuesday.
"The backstory is a mystery, because where he found it is in a debris field of one plane crash, a 1972 crash, and only a few hundred yards from where a ValuJet went down in 1996," Walker said.
Walker said he is trying to help Rubinstein find the rightful owner of the piece, but the effort may prove difficult as it does not bear any marks signifying its owner.
"The jewelers were all, what is it, what culture is it from, talking about the diamond surviving the heat, and I'm thinking, I'm sort of an expert on Celtic jewelry, Celtic crosses, and I weighed in and actually don't think it's Celtic. I think it's more Middle Eastern, Greek or Russian," he said.
Walker said he is hoping someone will recognize the jewel.
"We're thinking we've got to get this where people can see it so someone can say, 'Oh that belonged to my aunt' or something," he said.
