These are millefiori beads made in Venice, shaped like go stones. They resemble go stones, but have holes drilled through them. The last photo is an example brooch and is not included in the product. They are intricately made with a 6-layer chevron pattern thinly sliced and inlaid as a design. There are also egg-shaped ones with a similar design. This is a set of 10. If you need one or more, please contact me in the comments section. The discount rate increases with the number of items. The diameter is about 22mm, and the thickness is about 7mm. The hole diameter is about 2mm, so only thin string like fishing line can be passed through.
