4mm Heishi beads
 24K Gold metal beads
 4mm golden rondelles 24K
 A 24K Gold pendant
 A 24K Gold bail
 Silk thread
 Crimp beads
 A clasp
 From the extension chain

Take your silk thread and thread a crimp bead. Pass through the clasp ring and then back through the crimp bead. Flatten it with flat pliers after bringing it to the edge of the clasp. To secure the closure, you can make a double knot at the edge of the bead. Thread a metal bead at the edge of the crimp bead. 

Start threading the Heishi beads by alternating the colors. At desired spots, you can place a round bead or golden rondelle beads.

To add contrast, play with the colors and shapes of the beads!

Once you reach the center of the necklace, about 20cm in, place the bail mounted on the pendant and then go back symmetrically to finish the other part of the necklace.

Next, thread a crimp bead and an extension chain of about 3cm. Go back through the crimp bead.

Make sure to keep some flexibility in the necklace before flattening the bead. Make a double knot at the edge of the bead and then cut the thread.

To bring your creation to life, I recommend using at least 2 colors of Heishi beads and playing with the shapes of metal beads.

And there you go! Beautiful creation!
