A wishing stone is a stone that has a white line going completely around it. Legend has it that if you make a wish for yourself with the rock, it is said to come true, but if you make a with for someone else with it, their wish and all of yours are said to come true.
Several years ago a friend sent me a wishing stone. I fell in love with it. I now offer them in my shop. You can find them in my 'Beach Stone and River Rock Jewelry' collection: https://wearyourwild.com/collections/beach-stones-and-river-rock-jewelry
I'm always looking for more so check back often to see what's new to wish upon.
