The Sandstone Gem is the key item for completing Silver Beach. Legend says that it used to belond to the sea, until some fishermen caught it on his rod. The second the Gem became lifted out of the water, a big storm erupted, and has beem stormy ever since. the fishermen who caught it ran to his house, putting it in a hidden Chest before the rain made the house collapse. Nobody knows if this legend is true, because they searched all over the place, but no chest was found. They abandoned the project, and believed that it was a myth, and such a item could never exist.
