To find treasure in your backyard isn't something you'd expect.

Well, Sean Pratchler found a gold plated necklace while working in his backyard.

"The mulcher itself had dug up this root, I didn't think anything of it, I thought I'd cut the rest off when I come back to it, in the meantime, i believe that necklace was wrapped around the root the whole time but it was so muddy and dirty."

Pratchler attempted to find the true owner of the necklace.

low and behold, Deb Haryett says she lost the necklace while playing in the backyard as a child.

"I would have lost it playing in the yard because of course, you'd wear it. Because we're kids, we are not going to keep these forever."

The necklace has been underground for more than 50 years.

The Pratchler family gladly returned to the necklace to Deb Haryett yesterday.
