Begin by working with the lock charm. Use 2 pair of jewelry pliers–one on each side of the jump ring–to open jump ring at top. Remove clasp from gem and lock portion, as shown.
Now working with the clock pendant, use pliers to open the headpin. Remove bead and chain portion, as shown — save for a future project.
Using the jump ring on the clasp (from Step 1), attach clasp to top of clock pendant. Then use a new 6mm jump ring to attach gem and lock portion to bottom of clock, as shown.
Working with key charm, adhere one large gemstone to the center of key. Adhere another on the back.
Use jump rings to attach key charm and pearl bead charms to the connector loop on the gem piece, as shown.
