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