In June 2015，a friend shared an experience with me: while tidying up at night, she accidentally dropped three crystals, shattering them on the floor. Her friend comforted her, saying it was "warding off disaster" for her, and that as long as she was unharmed, it was all that mattered. At first, she didn’t think much of it—after all, what danger could there be at home? Not long after, however, her usually gentle Ragdoll cat suddenly started growling at the front door, its low, warning sound oddly dog-like. Neither she nor her husband had ordered any takeout, yet at 9:30 PM, the doorbell rang, pressed by a stranger claiming to be a delivery person. Alarmed, they chose not to open the door. Checking the security camera, they saw the stranger holding no food or package. They immediately called the police.The crystals had shattered at 8:30 PM—exactly an hour earlier. In that moment, my friend suddenly understood: perhaps the crisp sound of breaking glass had truly been a warning, a protective sign. From then on, we’ve been committed to helping more people understand crystals, so that more can embrace the luck, happiness, and health that crystals can bring to everyone’s life!
