I had this custom-made at a power stone specialty shop last year, but I've never used it, so I'm offering it for sale. The diameter of each bead is 1.2 cm. The color is gorgeous. Since it's a new power stone, you can remove the string and adjust the size if it doesn't fit you perfectly ❤︎ Power Stone Overall diameter: 7 cm Inner diameter: 5 cm I will wrap it in bubble wrap before shipping. Price negotiations are not possible. Immediate purchase is OK.
