Flat ring / donut shape. Size: total diameter is about 20mm, inner hole diameter is about 10-12mm
Pierced, can be stranded or sewed on. Pierced hole is drilled parallel to the flat sides, so when stranded the beads will be lined side to side as seen on photos
White / light ivory colour
Please note: as they are made of natural material (shell), there are some minor variations in colour, texture, shape and size, but overall they are well made, with smooth surfaces
I also have other similar mother of pearl beads listed in other colours and shapes
