Jewelry with waste

A couple of simple examples of how waste can be used for jewelry design.
These are the outcomes of some of iop's free time last summer.

Necklace made out of discarded guitar and bass strings plus some beads from a broken bead-belt. All the pendants (except the central one) are the ball ends of the strings.

 Brooch made from a bass string (external one), discarded electric cable (blue one) and a guitar string.
