Unique - handmade pendants. Many contain wire wrapped cabachons (undrilled gemstones) from around the world. Wire types include oxidized or bare copper, silver-filled copper or pewter, or gold filled/plated copper or pewter.
Bare copper wire is frequently left untreated as a design element. The copper will oxidize naturally over time to produce an antiqued patina. The copper can be maintained to keep a shiny surface if so desired.
