Strands of natural pearls
 Golden metal beads
 Silk thread
 Beads to crush
 Clasp and extension chain

To begin, separate your natural pearl strand in half to easily obtain the pearls corresponding to the two sides of the necklace. This will make stringing easier. 

Take the silk thread and thread a squeeze bead and your clasp, before passing through the squeeze bead again. Pull the thread back to bring the clasp to the end of the thread, keeping a piece of about 5cm.

Flatten the bead to be crushed, then tie two knots. to the edge of the bead with the threads to secure the threading.

Start stringing the beads...

Here we've alternated series of 6 beads and 9 natural beads (to give rhythm to the whole) with a cube bead between each series.

For the last series, we replaced the cube bead with a small cross loop. 

In the center of the necklace we placed a cube bead, a faceted bead, 15 4mm washers, a spinning top and again 15 washers, a faceted bead and a cube bead.

Then use symmetry to assemble the other part of the necklace.

At the end of the thread, place the bead to be crushed, an extension chain (approx. 3cm) and then thread back through the bead to be crushed.

Before tightening the bead, place the curved necklace in its final shape, keeping it flexible. Tie 2 knots at the edge of the bead to be crushed, then cut the wires flush.

There you go! Beautiful creation!
