Copper Bronze Tones Pendant Necklace & Three Pendants

I think copper alloy. Possibly copper clay. I don’t know what the bead is. It contains small pits and I’ve tested and it’s not glass. It doesn’t register on my gem tester but it doesn’t look like acrylic. It could be turquoise. 🤷‍♀️ Measure approximately Pendant Necklace 23” Pendants / charms 3/4”, 1.5”, & 2.25” ☀️Bundle items from my closet to save on shipping & get a 25% discount☀️
