I'm decluttering my collection of bracelets. Although they are new and unused, they have been opened for photography. Size: Approximately 8.6mm Inner Diameter: Approximately 15cm This is a power stone believed to guide the owner and give them courage and confidence when facing a crossroads in life and needing to make a decision. It is also said to have the effect of making you feel positive. If you have trouble breaking off a bad relationship, try wearing kyanite. You will gradually lose your attachment to the other person, and it will show you the path you should take. *Please understand that although these are new and unused, they have been handled by a person once before purchasing. They have been stored at home (no smoking, no pets). Please refrain from purchasing if you are concerned about minor details. *Regarding the size, please consider it as a guide only, and please understand that there may be slight errors due to amateur measurements. *They are also listed on other apps, so they may be deleted. *Also, please note that we do not accept returns or refunds.
