Jewelry stores sell them, but there is no rope when they sell them. After you buy it, the clerk can help you braid the rope, generally about 1 gram each, and about 270 grams of gold per gram. If the brand is good, for example, Chow Tai Fook now has more than 320 grams per gram, and generally odd-numbered beads will look better. It is suggested to use 65,438+0 or 3, and it is best not to engrave on beads. If you really want to carve, choose full light or full light.
