Funky Festival Necklace

I found this standout piece at a music festival in Milwaukee, WI many years ago. Sadly, I don't remember who the original artist is. My best guess at the materials: - shimmery, brown & gold, rectangular resin base for the pendant - glued on burlap, opalescent shapes - mixed beads (stone, glass, wood, metal) - metal wire - translucent, acrylic string - sturdy, metal clasp
