I saw this horror film in the late 80s or early 90s. All I remember was the desert and a necklace or pendant being found. It was given to a girl. The pendant/necklace was evil and I think it made the girl possessed. I think it was found by an archaeologist who was the father to the girl. It was definitely moreof a B movie, not a big hit.
Manhatten Baby?
“Manhattan Baby”(1982). Spelled it incorrectly.
