Semiprecious Gem Goldtone Statement Necklace

Gorgeous semiprecious gemstone statement necklace. I think the stones are moss agate? The stones are peaceful shades of green with natural dark green inclusions in the crystals. Iridescent light blue crystal accents. The stones each measure between 1.5” to 2”. Goldtone chain is substantial and an interesting link. Excellent condition. Never worn.
