I would agree with Jim Gibb, but place it slightly earlier. I think in looks to me like a pendant inspired by the primitivism of artists like Picasso. Not his drawings, but his work on ceramic inspired by Don Quixote. I'd ask an art historian interested in design history of the past century. Either way, I wouldn't use the work 'fake' to describe it. It's a real pendant.
Best,
Tim
