The beads are around 5mm measured from hole to hole, and around 9mm in diameter.
A photo of the beads next to a penny is included to help give an idea of scale. The penny is not included with your purchase :)
Made on 1/16" mandrils (this is an approximation of the hole size)
Italian art glass (Moretti/Effetre)
All of my beads are carefully annealed in a digitally controlled kiln for durability. They are created by myself (Self Representing Artist #H27), in my home studio on beautiful Vancouver Island on the West Coast of British Columbia.
