I Spy...

This ornate bronze pendant is double-sided.  One side holds a picture of an eye and the opposite side

 holds what the eye is spying - resin and inclusions of a small key, a pearl, a piece of text that says "for the lovers", three small "diamond" rhinestones, ribbon, a tiny shell bead, and several glass shards.  The pendant is attached to a sterling silver bail which holds a coil of wrapped iron wire and a disk of  eye shaped bronze.  A lovely large faceted aventurine teardrop dangles at the bottom of the pendant.

  I've placed it on a sterling silver chain with a toggle and clasp.
