I can't. The positioning buckle can't reach the jewelry line. Usage of locating buckle:

1. First, tie the knot as usual (more than twice), but be sure to tighten it a little, and finally hide the thread.

2. Secondly, take a locating buckle, and both the left and right wires pass through the locating buckle.

3. Finally, clamp the locating buckle with pliers.
