These silver ceramic spacer beads are my top sellers as they are so useful and work particularly well with artisan lampwork beads. I also have them in bronze, copper, patinated copper and antique silver, plus they are available in 40 colours, so you are almost bound to find the right colour to complement your design. Don't forget they come in 6mm, 13mm, 16mm and 20mm as well.
Let me know if you want a particular listing made for you.
Size: 8 - 8.5mm x 2 - 3mm
The hole will take 1.8mm cord. i have used a micrometer to take these measurements.
