The agate beads in Yuan Dynasty were transparent and exquisite in craftsmanship. In ancient times, old agate objects were generally processed by hand, leaving artificial traces on the objects. If it is drilled manually, the holes of the old agate beads will be trumpet-shaped, while the modern agate jade carving process is mostly done mechanically, and the drilled holes will be smooth.
