Large Native Style Turquoise Oval Statement Necklace Charm Unique Chunky Silver

I wish I knew if this was real turquoise or lab created or just some other similar stone, but this is not my area of expertise, so I am pricing in the middle, comms range anywhere from 35 for faux to 350 for real. Silver toned. No markings. The charm is heavy, the chain is lightweight and poorer quality. Thanks for viewing! Open to offers!
