These beautiful Czech glass beads measure 17mm and are 3mm deep. They are laser etched on both sides with an iridescent or chrome clock face design. Now available in three colours: Matte black with iridescent faces, Black (shiny) with iridescent faces or black with chrome faces. The iridescent faces come in a mix of blue/green/yellow finishes which is random. Some have both colours on the different faces as per the photo, and some are more one tone that others. If you would like a particular colour over another please leave a note in the comments box at checkout and I will try to select one to suit where possible.
