This is a costume jewelry. The stones are plastic and very lightweight, but have an excellent color and look fantastic on, which mean that this piece is a wonderful addition for your jewelry box adding color and flexibility to your jewelry choices. This necklace is perfect to wear with summer outfits, but also goes very nicely with a turtleneck sweater for all year round use. The turquoise and gold combination along with the black silk-like rope chain are a lovely combination and are very complimentary. This necklace is 20" long and has only been previously worn twice.
