Twisted link chain
 Miyuki Delica 11/0 beads
 Brass wire
 A carabiner clasp
 Crystal Quartz beads
 4mm rings
 Metal teardrop beads

To start, cut 2 pieces of chain. The first about 7cm and the second about 8.5cm. With this chain, you can attach the carabiner directly to the links, allowing you to easily adjust your bracelet without adding an extension chain.

Then cut a piece of brass wire about 20cm. Form a loop at one end of the wire while keeping about 1.5cm of wire.

String the link of the chain through the loop then wrap the small wire (1.5cm) at the bottom of the loop for 2 turns. Cut the excess flush.

String a Miyuki bead, a teardrop bead, the Quartz bead, then symmetrically, the teardrop and the Miyuki bead. 

Then form a loop 1mm from the last bead strung and then form a loop. String the other chain then wrap the wire at the edge of the loop for 2 turns. This allows for a very strong attachment!

Next, to decorate the Quartz bead, take a piece of brass wire, wrap one end of the wire around 1 turn between the teardrop bead and the Quartz bead. Cross the wire over the bead then pass behind the other teardrop. Cross the wire over the bead again then pass behind the teardrop. Go straight down towards the other teardrop, pass behind then go straight up towards the teardrop. Wrap the wire once then cut flush.

You should get an X on the bead and 2 straight wires on the edges of the X. 

To finish, connect the carabiner to the shortest chain with a 4mm ring.

And there you go! Beautiful creation!
