I will be listing items little by little to organize my collection. * To prevent any problems, please ask any questions you may have regarding the size of the beads, inner diameter, etc., before purchasing. Please be aware that you will not be able to confirm these details through images after purchase. * There may be small chips, cracks, and scratches. Thank you for your understanding. #NaturalStone #NaturalStoneBracelet #WhiteGarden
