This heavy 22K and 14K gold piece can be worn as an enhancer, a brooch, or a necklace. It is the ultimate transformer. The peridot is large, bright and kicky, AAA quality. I believe the Ammolite is untreated. Ammolite is opalized Ammonite fossil from Southern Alberta, Ca. The bezels are 22k Gold and the underbezels and connectors are 14K gold. The beads included are Peridot and apatite with seed pearl accents. You can wear the pendant and the beads independantly for maximun versitility.
