The processing time of round beads is long, the processing technology is difficult and the material cost is high. In contrast, except for the shape requirements, other standards and difficulties of straight-cut beads are not so high, and the shape does not need to be very precise. Even if there are some differences, the overall image has not been greatly affected.

There are many kinds of jewelry and jade carving themes, which can be said to be all-encompassing. Similarly, there are many kinds of beads. In addition to round beads, there are barrel beads, old beads, sliced beads, abacus beads, straight-cut beads, and some special-shaped beads such as bamboo beads, gourd beads and diamond beads.
