I purchased this power stone bracelet from STAR MOON in Miyajima a few years ago. It's for career luck. I collected several and kept them in a collection case, only trying them on occasionally. I would occasionally cleanse them by bathing them in moonlight on the full moon. There are some areas with cracks, which are characteristic of natural stones.
