a ball chain
 3 natural stone tube beads
 6 golden rondelle beads
 3 eye pins
 3mm rings
 an extension chain
 a lobster clasp
 jewelry creation pliers

This jewelry is very simple to make, for this mount the natural stone tube beads, surrounded by 2 golden rondelle beads, on eye pins.

Form a loop similar to the one on the pin. A small loop will be more discreet and will give a nicer finish to your creation.

Be careful for a nice fall, make the loop perpendicular to the existing loop. Thus, once the beads are connected together, they will sit perfectly in a chain.

Assemble the 3 bead assemblies together by connecting the loops.

Here we have made a choker of 42cm (without the extension chain value) so that the beads sit at the level of the collarbones, but you can adjust the size to your liking.

Remove 6cm (size of the bead assembly) from your measurement. For example, 42cm - 6cm = 36cm

Then divide the obtained measurement by 2. So 36cm : 2 = 18cm

Now cut 2 ball link chains to size.

Widen the links at the ends of the chains with a reamer. This will make it easier to pass the rings through the links.

Now connect the chains on each side of the beads directly to the loops of the pin.

To finish, place the clasp and 3cm of extension chain at the ends of the chain with 3mm rings.

And there you go! Beautiful achievement!
