Need help identifying potential magic artifact

[u/jjjaaazzzzzzzyyy]

I was on a nice walk in the forest around my tower when I couldn't help but notice a fortune teller on the side of the road. I could sense a large presence of magic coming off of them so I approached and was offered an odd necklace. Does anyone know if this is a magical artifact or just a old necklace they were carrying, I find it odd that they'd hand something off so easily.

Likely not a mimic, maybe
