This design is made by Pia and is one of a kind. The listing is for the disc bead you see in the photos, in gray and beige tones, with little organic craters and fungi, organic shape, approx. 53mm across, hole is 3 to 4 mm. Made of ceramic, fired in our kiln at 1150degrees Celsius
Please take a look at all the pictures to get a better idea, there's a photo with a ruler to help you with sizing, and closeups to check the quality you can expect.
Measurements are approximate as the beads are shaped by hand, one by one.
