Larimar Approximately 7.9mm Inner circumference approximately 16cm (size cannot be changed as it is a ready-made product). To prevent color transfer, the blue nylon elastic cord used at the time of purchase has been replaced with a white nylon elastic cord and strung loosely. It looks like ice larimar (white larimar). It includes beads with color unevenness, black parts, and flat parts instead of perfect spheres. The stones have small scratches, dents, color unevenness, and chips near the stringing holes. Please refrain from purchasing if you are looking for perfection. 10243
