Materials needed for the realization :

• Silver chain of your choice for the necklace (40-45cm recommended)
• Silver chain of your choice for the pendant (length of your choice).
• 2/3mm reconstituted turquoise beads
• 8mm reconstituted turquoise bead
• Silver wire* (optional)
• Silver open rings*.
• Silver lobster clasp
• Silver extension chain
• Silver flat head nail*.

*Choose diameters that will fit through the chain links

Tools for making :

• Round-tip pliers
• Flat head pliers
• Cutting pliers

Steps to follow:
Collar :

Cut the chain for the necklace into two pieces of equal length, Take the piece of silver wire and thread the 2/3mm turquoise beads onto it

Pass the end of the two pieces of necklace chain over the silver wire, And make the pigtail loop with the wire using the round nose pliers and thread the chains through the loop before closing the pigtail loop, Cut off the excess wire.

Then pass the free end of the necklace chain through an open ring, Do the same for the extension chain (in the same ring), Close the ring with the clamps

On the second end of the necklace chain, pass the chain through an open ring, And the clasp ring in the same open ring
Close the ring

Pendant:

Repeat the process on the other end of the silver wire, but with only one chain (pendant)

Then thread an 8mm turquoise bead onto a flat-headed nail/pin, Then thread the free end of the pendant chain 

Make the pigtail loop with the pin with the help of the round tip pliers, Thread the chain through the loop before closing the pig knot. Cut off the excess thread and then it's done.
