As the stone's properties suggest, it seems like it will bring peace and a gentle heart. Natural stones: Amethyst, round 6mm Rose Quartz Metal fittings: 14KGF Length: Approximately 19cm (including clasp). It has a hook, making it easy to remove. It's a bit longer than others. 14KGF is resistant to discoloration and lasts a long time, and it is also suitable for those with allergies, but it may not be suitable for everyone. After use, wiping it gently with a soft cloth will make it last even longer. We make it with care, paying attention to the materials. Thank you for looking.
