macramé jewelry thread in 0.5mm
 natural beads 6mm
 metal beads of different sizes and shapes
 a board and a clamp
 a lighter or a candle
 a wire cutter or scissors

This method is quite simple, we will first make a series of knots diagonally as shown in the video below. Then at the center of the necklace, we insert metal beads and a nice natural bead in the center.

To start, cut 5 threads of about 1.5 meters each. Plan for a good length because you won't be able to make connections during assembly at the risk of having to start all over again!

Start the knots by coming from about the center, it will be easier to adjust the length of the necklace.

In this technique, the outer thread will be the weft thread, it goes over the others. Then each thread will make 2 knots on the weft thread. When you want to place beads, you will need to thread them before making the knots.

Make a first series of knots diagonally, then insert a metal bead on the weft thread (that's the one that goes diagonally, the one on which we make knots with the other threads) then make the knots with the 3 threads. 

Before making knots with the last thread, thread the small metal beads. Here we have put 1 cube bead 2mm, 2 beads 3mm, a pendant, and again, 2 beads 3mm and 1 cube bead 2mm. Then secure the row of beads by making the 2 knots.

Go back in the opposite diagonal while making knots with the threads.

Then repeat the operation with the beads, but this time on the 3rd thread you will thread a 6mm bead. Continue symmetrically...

Then create as much weaving as you want, and to finish the necklace, braid the remaining threads into a 3-strand braid (gather the outer threads in pairs and leave the central thread alone).

To give you another visualization of the technique, you can check out the video of the bracelet.

And there you go! Beautiful achievement!
