1. Drill the hole.
Using a dremel and a diamond bit shaped like a BB, drill a hole in one end of the jade.
It can take a while, since jade is very hard, but in the end it should look like this.
Take a length of 1mm leather cord and crease it in half. Push the crease through the
hole like so.
3. Tightening & Clasping
Push the free end through the loop and pull tight. Attach ends and clasp like so.
Ends, clasps, and leather can be purchased at Michael's, A.C. Moore, and other craft
