Stylish necklace using rose quartz and hematite. The length is approximately 41cm and is not adjustable. I purchased this a long time ago through a connection at a jewelry store in Ginza, but I have never used it. The clasp opens and closes without any problems. You can use it as is, or you can disassemble it and use the materials. - Materials: Rose quartz, hematite - Design: Bead necklace - Colors: Pink, black Thank you for looking.
