Bugle beads with a rainbow finish, often called "iris" or "aurora borealis" (AB), are cylindrical glass beads that exhibit a multi-coloured, iridescent effect on their surface. This effect creates a shimmering, rainbow-like appearance, adding a vibrant and dynamic element to jewellery and craft projects. The beads are made of glass and come in various lengths and sizes, with the rainbow finish applied over different base colours or finishes.
