Inner diameter approximately 18cm. This is a Larimar bracelet with a gradation of approximately 10.5mm for the smaller Larimar beads and approximately 16mm for the larger ones. I purchased the beads individually and created an original design. This is part of my collection, which I am now selling, as I have only taken photos of it. Please note that as these are natural stones, there may be chips or cracks. I will not be using any cushioning material when shipping. Please consider carefully before purchasing if you are concerned. Also, please ask any questions you may have before purchasing (*^^*) I would be happy if it could find a home with someone who feels a connection to it (*^^*) #Larimar #DominicanRepublic #LarimarBracelet #Bracelet
