Jade can be punched by ultrasonic waves, and the high-frequency vibration generated by ultrasonic waves makes the small needle drill move up and down at high speed to drive the abrasive to punch holes. You can also drill holes on both sides, drilling holes from both sides of the jade, just hitting the middle of the object.

Find a beverage bottle, drill a small hole in the outer edge of the bottom of the bottle with a needle or drill, and then fill the beverage bottle with water; When the beverage bottle filled with water is suspended, a small water column will flow out of the small hole, and the cooling device will be completed.

Use sewing needles. Tie the rope to be strung on the jade pendant to the sewing needle, then let the sewing needle pass through the hole with the rope and untie the sewing needle. Make the hole bigger.

Rub the thin thread, and rub the rope end into a thin thread, which can easily pass through the small hole of jadeite. The hole of the jade pendant is too small, so some tools can be used to help thread the rope. For example, you can prepare basic tools first, such as lighters, ropes, and preferably pliers with pointed ends.

If there is no hole, you can consider gold plating, making a base inlay, or weaving a knot to wrap the edge. Of course, you can call again. Generally, non-porous jade ornaments are usually smaller and thinner, and it is better to choose gold-plated ones.
