An Australian woman was surprised to learn that her boyfriend had tricked her into carrying around her engagement ring in her necklace for more than a year.

Anna and Terry, a couple in Tasmania, Australia, had been dating for one year when she received the necklace as a gift.

"I had always loved the idea of giving someone a gift where they didn't know its true value until years later," Terry told ABC News.

Terry gifted Anna what he described as a "spiral shell" necklace made from Huon Pine.
