If you're going to propose, you might as well make it as unique an experience as possible. One man from England did just that recently when he decided to bury his engagement ring on the grounds of an old castle in England.
Jamille Swainson hid the sapphire and diamond studded engagement ring in the ground before taking his girlfriend, Harriet Haseler, on an "activities day," which included using metal detectors. It seems Harriet grew up doing such activities with her grandmother. Only this time she came across a metal box shaped like a military drum. When she opened it, there was a hessian sack inside where the ring was being hidden.
Harriet said they had been finding all sorts of things that day with the metal detector and thought she had just found an old box with some old jewelry in it. That is, until she realized he was down on his knee asking her to marry him. She said yes and there in the midst of planning their special day.
