A large flat ivory bead of irregular shape (2 pcs)
Presumably, an initial cylindrical shape of the blank was made with a push-plane. The bead plate-blanks were cutted with a knife which was used as a saw. There are some traces of cutting on the planes, and some traces on push-plane work are on the ends. The hole is made with a reamer and was drilled from both sides.
Use-wear traces are not found.
Diameter - 15,2-14 mm
Thickness - 2,1-2,2 mm
Diameter of the hole - 1,23 mm
